The 2017 World Baseball Classic (WBC) was an international professional baseball competition, composed of 16 competing nations, held from March 6 to March 22, 2017. It was the fourth iteration of the World Baseball Classic. The first-round hosts were Seoul, Tokyo, Miami and Zapopan. The second-round hosts were Tokyo and San Diego, and the championship round was played in Los Angeles.


2017 World Baseball Classic
Twelve of the sixteen competing nations qualified based on their performance during the first round of the 2013 tournament; the remaining four nations are the winners of four qualification tournaments that took place in February, March and September 2016. Two of the four qualifiers, Colombia and Israel, each made their first appearance in the WBC, and both have secured their positions for the 2021 World Baseball Classic.


2017 World Baseball Classic

2017 World Baseball Classic, Qualification
The top three teams from each pool of the first round of the 2013 World Baseball Classic automatically qualified.


2017 World Baseball Classic, Format
The first and second rounds of the tournament were played in round-robin format, with each team playing each other team in their pool once, as was the case in 2006. However, in an effort to reduce the likelihood that a team would be eliminated on statistical tiebreakers, the tournament schedule allowed for a seventh game at each pool-play site.


2017 World Baseball Classic, Format
In either of the latter cases, the statistics used to rank the tied teams were:

2017 World Baseball Classic, First round, Pool A
Pool A of the First Round of the 2017 World Baseball Classic was held at Gocheok Sky Dome, Seoul, South Korea from March 6 to 10, 2017, between Team Israel, the Netherlands, South Korea, and Taiwan. Pool A was a round-robin tournament. Prior to the start of the tournament, ESPN considered Team Israel, ranked 41st in the world, to be the biggest underdog in the tournament, referring to them as the "Jamaican bobsled team of the WBC".


2017 World Baseball Classic, First round, Pool A
Team Israel (3–0) and Team Netherlands (2–1) qualified for the second round, in Japan. Israel became the first baseball team to go undefeated in the first round of the WBC's main draw after entering the main draw by winning in a qualifying round. In what NBC reported was thought to be the tallest batter-pitcher matchup in baseball history, the Dutch team's 7-foot-1-inch (2.16 m) Loek van Mil walked Israel's 6-foot-8-inch (2.03 m) Nate Freiman. Israel's catcher, Ryan Lavarnway, was named Pool A MVP, after going 5-for-9 (.556/.692/.889), with four walks, a home run, and three RBIs.

Two-time champion Japan concluded Pool B with a 3–0 record. Cuba defeated Australia to advance to the second round. In the first round, after batting .364, Japanese outfielder Yoshitomo Tsutsugoh was named the Pool B MVP.

2017 World Baseball Classic, First round, Pool C
After falling behind 5–0 in the sixth inning, Dominican Republic rallied to defeat the U.S. 7–5 in their second game. On the last day of the pool, Colombia tied their game against Dominican Republic 3–3 in the eighth on a Jorge Alfaro home run, and had a chance to win in the ninth inning, but Oscar Mercado was called out at home trying to score on a sacrifice fly. The game continued into extra innings, where Dominican Republic scored 7 runs in the 11th to win and finish the pool undefeated. The U.S. then took an early lead on Canada, winning 8–0 to claim the second berth in San Diego. Manny Machado of the Dominican Republic was named MVP for the first-round Pool C bracket of the WBC, after batting .357.

2017 World Baseball Classic, First round, Pool D
While Puerto Rico cruised in all three of its games, the fight for the other three places was extremely tight. Italy scored 5 runs in the bottom of the 9th inning to shock Mexico in the first game, then lost an extra-inning slugfest against Venezuela. In the final game, Mexico defeated Venezuela in another slugfest and thought they had scored enough runs to advance on tiebreakers, though this turned out not to be the case.


2017 World Baseball Classic, First round, Pool D
The first tiebreaker criterion is fewest runs allowed per defensive inning played (RA/IPD) in the games among the tied teams. Although Mexico allowed the fewest runs in those games (19, to Italy's 20, and Venezuela's 21), Mexico played fewer defensive innings (17, while the other two teams had 19) and thus had the highest average RA/IPD (1.117, to Italy's 1.053 and Venezuela's 1.105). This occurred for two reasons: the Italy-Venezuela game went 10 innings, and Mexico was the road team while losing to Italy.


2017 World Baseball Classic, First round, Pool D
In fact, the Mexico-Italy game did go into the bottom of the 9th, in which Italy scored runs that were charged against Mexico but Mexico failed to record an out. There was confusion during and after the Mexico-Venezuela game, with an initial calculation showing that Mexico had advanced. Mexico filed a formal protest of its elimination, but the protest was denied.


2017 World Baseball Classic, First round, Pool D
As specified in the rules, Mexico was eliminated by the tiebreaker calculation and a tiebreaker game was played between Italy and Venezuela, which Venezuela won with a 9th-inning rally.


2017 World Baseball Classic, First round, Pool D
According to the rules as announced at the time, Mexico's last-place finish would have required it to participate in a qualifying tournament in order to re-qualify for the 2021 World Baseball Classic. However, MLB announced in 2020 that the field of teams for the 2021 WBC would be expanded, with all 2017 WBC participants qualifying automatically and four new teams coming from qualifying tournaments.

Undefeated Japan (3–0) and the Netherlands (2–1) advanced to the semi-final round, as Israel (1–2) came in third, and Cuba (0–3) fourth.

2017 World Baseball Classic, Second round, Pool F
Pool F started with Puerto Rico handing the Dominican Republic its first loss since the 2009 World Baseball Classic. Puerto Rico ended Pool F still undefeated and Venezuela was eliminated, going 0–3. The final game of the pool was a rematch between the United States and Dominican Republic to advance to the championship round. The DR took an early 2–0 lead in the first inning, but the United States came back to win 6–3 to eliminate the defending champions.

In the final standings, ties were to be broken in the following order of priority:


2017 World Baseball Classic, Final standings
When the 2017 WBC was played, it was assumed that the field for the following 2021 WBC would remain 16 teams. Under the qualification format in use at the time, the bottom four finishers from 2017 (Canada, China, Mexico, and Chinese Taipei) would've been forced to re-qualify for 2021. However, in January 2020, MLB announced it was expanding the field for the 2021 WBC from 16 teams to 20 and that all 16 participants from 2017 would receive automatic bids for 2021, thus sparing the bottom four nations from relegation to the qualifiers.

The first tiebreaker criteria is fewest runs allowed per defensive inning played in the games between the tied teams. Mexico allowed 19 runs, Italy allowed 20 runs, and Venezuela allowed 21 runs. Italy and Venezuela played 19 innings each in the two matches, therefore their RA/IPD were 1.053 and 1.105. Mexico played 18 innings, but they recorded no outs in the ninth inning of their game versus Italy, therefore the inning did not count towards their RA/IPD of 1.117.

2017 World Baseball Classic qualification
The Qualifying Round of the 2017 World Baseball Classic was held from February 11 to September 25, 2016. Teams which participated at the 2013 World Baseball Classic were automatically qualified for the 2017 tournament except the four nations which ended up last in their respective groups: Australia, Brazil, Mexico, and Spain had to play in the qualifiers along with 12 other national teams. 16 teams participated, divided into four groups of four teams each. The winners of each of the four groups qualified for the 2017 World Baseball Classic.


2017 World Baseball Classic qualification
The qualifiers were organized as four independent modified double-elimination tournaments featuring four teams each. The final game was winner-take-all, even if won by the team emerging from the loser's bracket. That is, the team emerging from the winner's bracket might be eliminated despite losing only one game.


2017 World Baseball Classic qualification
Australia, Mexico, Colombia, and Israel won their qualifiers and participated in the 2017 tournament. In their respective brackets, both Australia and Mexico were top seed (signified by home-field advantage) as well as the team that had competed in the 2013 tournament. However, Colombia defeated top seed Panama as well as 2013 participant Spain to advance, while top seed Israel defeated 2013 participant Brazil.


2017 World Baseball Classic qualification, Players, Minor league players
Qualifier 1 featured 16 players who were affiliated with Major League clubs. Nine MLB-affiliated players were on the Australia roster, three on the South Africa roster, two on the New Zealand roster, and two on the Philippines roster.


2017 World Baseball Classic qualification, Players, Minor league players

2017 World Baseball Classic qualification, Players, Experienced Major League players
Only a few experienced Major Leaguers participated in the spring qualifiers. These included relief pitcher Peter Moylan of Australia, first baseman Adrián González and pitcher Óliver Pérez, both of Mexico, and catcher Carlos Ruiz of Panama.


2017 World Baseball Classic qualification, Players, Experienced Major League players
Qualifier 4 took place in September, after the end of the minor league season but during the Major League season, and thus no active Major League players participated. Although Brazil had a few young Major League players, Israel was the team most likely to be adversely affected by this circumstance. In 2013, Israel also was placed in a qualifier that took place during the Major League season and thus was unable to include a number of Major League players of Jewish descent who had expressed interest in playing for Israel. Without these players, Israel narrowly lost its 2013 qualifier to Spain.


2017 World Baseball Classic qualification, Players, Experienced Major League players
Israel's roster included eight former Major Leaguers: catcher Ryan Lavarnway, infielders Ike Davis, Cody Decker, Nate Freiman and Josh Satin, and pitchers Josh Zeid, Jason Marquis and Craig Breslow. On the other hand, infielder Ty Kelly, one of Israel's twenty minor leaguers, had to withdraw from the qualifier after he was called up to the New York Mets.

A mercy rule came into effect when one team led by either fifteen runs after five innings, or ten runs after seven innings.


2017 World Baseball Classic qualification, Additional rules
An alternative version of the IBAF's extra inning rule was also used. If after 10 innings the score is still tied, each half inning thereafter starts with runners on second and first base. The runners are the eighth and ninth hitters due in that inning respectively. For example, if the number five hitter is due to lead off the inning, the number three hitter is on second base, and the number four hitter on first base.


2017 World Baseball Classic qualification, Additional rules
For the first time in the World Baseball Classic, this rule was actually employed in this year's qualifiers, as the Qualifier 2 game between Nicaragua and the Czech Republic went into the 11th inning. Nicaragua scored three runs in the top of the inning, the Czech Republic only two in the bottom, so Nicaragua went on to the final game of the bracket.

2017 World Championships in Athletics – Men's 10,000 metres
The men's 10,000 metres at the 2017 World Championships in Athletics was held at the London Olympic Stadium on 4 August. This was billed to be the final 10,000 metres race of two-time champion Mo Farah. Farah won the race, ahead of Joshua Cheptegei from Uganda with Paul Tanui of Kenya finishing third. The win was Farah's third consecutive World 10,000 metres title, and his fifth consecutive major (Olympic or world) 10,000 metres title.


2017 World Championships in Athletics – Men's 10,000 metres, Summary
Joshua Cheptegei, Geoffrey Kipsang Kamworor and Moses Kurong formed an early breakaway, Kurong taking the lead for a few laps before Cheptegei went back to the front, and nine laps into the race, Kamworor, and then Paul Tanui, took the lead. By 6,000 metres, there was a lead group of 14 runners at the front, but this group gradually got smaller. Farah hit the front just before four laps to go. He let Abadi Hadis resume the lead, and at one point Kamworor had his heels caught by Farah as he cut across in front. Just before two laps to go, Farah went back into the lead.


2017 World Championships in Athletics – Men's 10,000 metres, Summary
During the penultimate turn, Tanui clipped the back of Farah's heels causing him to briefly lose his stride. Tanui sprinted through the final turn trying to get even with Farah at the head of the final straight.

2017 World Championships in Athletics – Men's 10,000 metres, Results
The final took place on 4 August at 21:20. The results were as follows ():


2017 World Championships in Athletics – Men's 100 metres
The men's 100 metres at the 2017 World Championships in Athletics was held at the London Olympic Stadium on 4−5 August. This meet was announced as the last competition for Usain Bolt. The race was won by Justin Gatlin of the United States, ahead of Gatlin's team-mate Christian Coleman, with Usain Bolt finishing third.


2017 World Championships in Athletics – Men's 100 metres, Background
Billed as his last individual race, world record holder and reigning world and Olympic champion Usain Bolt hoped to bow out of individual competition with one last gold medal. He originally planned to retire after the Summer Olympics in Rio De Janeiro the previous year, but decided to return due to his love for the London crowds. However, his season was hampered by his reoccurring hamstring injuries, as well as the death of his friend Germaine Mason. Coming into the championships, Bolt was only ranked 7th with 9.95 seconds.


2017 World Championships in Athletics – Men's 100 metres, Background
Meanwhile, young American Christian Coleman burst onto the athletics scene as the new favorite to dethrone Bolt, clocking a world-leading 9.82 seconds at the NCAA Championships and going on to win the 100-200 double. His only defeat came at the US Championships, where fellow Tennessee Vol and 2004 Olympic champion Justin Gatlin overtook the inexperienced Coleman, who overstrided towards the finish. The win came as a surprise for many, as the 35-year old veteran and 2005 world champion had an unusually rocky season despite being Bolt's biggest rival for the previous 4 years.


2017 World Championships in Athletics – Men's 100 metres, Background
Andre De Grasse of Canada also announced his intentions to defeat Bolt before his retirement; the triple medallist at the Rio Olympics proved he had the talent and confidence to stay calm against Bolt, especially when he rushed to the Jamaican's shoulder during the 200m semifinals. Despite not having gone under 10 seconds before the championships, many knew that De Grasse was a championship performer and would clock much faster times in London.


2017 World Championships in Athletics – Men's 100 metres, Background
Meanwhile, Bolt's training partner and  2011 World Champion Yohan Blake, continued his injury comeback by winning the Jamaican 100m title in 9.90, the second fastest time of the year. Julian Forte and Senoj-Jay Givans, two sub-10 runners, filled out the Jamaican squad. Akani Simbine of South Africa was ranked 3rd in the year with 9.92, and won at the Doha Diamond League in May, though many believed he peaked too early as South African runners began their seasons in February.


2017 World Championships in Athletics – Men's 100 metres, Background
Christopher Belcher, the NCAA bronze medallist behind Coleman and ranked 4th in the year with 9.93, joined Coleman and Gatlin on the US squad. CJ Ujah of Great Britain appeared to be in top form, winning 3 Diamond League races in Rome, London, and Rabat, the latter in 9.98 seconds. In his absence, the incredibly fast-finishing Reece Prescod beat out former European Champion James Dasaolu at the British Championships. Other key players included co-European record holder and 3-time global finalist Jimmy Vicaut of France, 7th-ranked Thando Roto of South Africa, and Rio finalist Ben Youssef Meite of the Ivory Coast

Just days before the championships, De Grasse pulled out with a hamstring injury and was forced to miss his final chance to defeat Bolt.


2017 World Championships in Athletics – Men's 100 metres, Summary
Coleman won his heat with ease in 10.01. Japanese runner Abdul Hakim Sani Brown placed himself as a favorite and surprised many by beating Blake in the second heat. Julian Forte of Jamaica was the fastest in the round, clocking 9.99 seconds in the third heat; Simbine finished 4th and qualified for the semis as a fastest loser, almost confirming claims he had already peaked earlier in the season. In the final heat, Bolt won with his slowest time of the season; his terrible start showed signs that he was, indeed, retiring at the right time.


2017 World Championships in Athletics – Men's 100 metres, Summary
In the first semi-final, Justin Gatlin qualified but seemed to struggle, losing to Akani Simbine of South Africa. Both were favorites to dethrone Bolt. In the second semi-final, Yohan Blake barely held off the hometown favorite Reece Prescod, who had a sudden surge of speed in the last ten metres to take the automatic qualifying spot from Su Bingtian of China. Run into slight headwinds, the first two semis were unimpressive, slower than ten seconds.


2017 World Championships in Athletics – Men's 100 metres, Summary
In the third semi-final, Christian Coleman surprised the world by beating Bolt with 9.97 to his 9.98, despite it being a semi-final; in doing so, he became the first man in four years to beat Bolt, the last being Gatlin by the same margin (0.01) in an IAAF Diamond League event in Rome. Coleman rocketed out of the start, while Bolt lumbered. Bolt tried to make up the gap, but sensing he couldn't catch him, eased up at the finish. Bolt's time was still the second fastest in the semis.


2017 World Championships in Athletics – Men's 100 metres, Summary
In the final, Bolt was lined up in lane four, right next to his young rival Coleman. Gatlin lined up in lane eight, with Blake right next to him. At the gun, Coleman got the quickest reaction time, of 0.123, and Bolt with the second slowest in 0.183. Coleman continued with his usual fast start, with Bolt next to him lumbering behind by a metre in fourth expecting to make up ground on Jimmy Vicaut of France and Su Bingtian inside him.


2017 World Championships in Athletics – Men's 100 metres, Summary
Meanwhile, the other half of the field seemed to struggle in the first 40 metres, but began to catch up with the pack afterwards. At that mark, Bolt began making up ground, first on Su, then on Vicaut. With every step, Bolt gained on his young rival, but as he got closer he began to tense up. Suddenly, with 15 metres to go, Gatlin in lane eight came out of nowhere and surged ahead of the two, securing his  first world title since 2005 by 0.02 seconds.


2017 World Championships in Athletics – Men's 100 metres, Summary
Gatlin's winning time of 9.92 seconds was the slowest World Championship winning time in the 100 metres since  2003, but was a new Masters world record, beating Kim Collins' 9.93 that he set the previous year. Coleman finished second in 9.94 seconds, while Bolt was third in 9.95 seconds, equaling his seasonal best that he set in Monaco.

From the gun in the final, the Kenyan team took charge as Elijah Manangoi from the inside and Timothy Cheruiyot from the outside squeezed the pack behind their wall. The third Kenyan, Asbel Kiprop went to his typical position marking the back of the pack. After a moderate lap, controlling the pace, Kiprop moved forward and the two leaders accelerated to a quick five metre breakaway. In the next half lap, that break expanded to 10 metres with only Kiprop able to bridge the gap.


2017 World Championships in Athletics – Men's 1500 metres, Summary
Through the next half lap, three men, led by Filip Ingebrigtsen (NOR), followed by Adel Mechaal (ESP) and Sadik Mikhou (BHR) were able to bridge the gap, with Ingebrigtsen able to reach the trailing Kiprop on the inside at the bell. Ingebrigtsen was able to hold the inside, making Kiprop run to the outside through the penultimate turn. Down the backstretch Mechaal was also able to pass Kiprop, who was struggling. The sweep was broken but Cheruiyot and Manangoi were still in front, Cheruiyot holding the leading inside position.


2017 World Championships in Athletics – Men's 1500 metres, Summary
Coming off the turn, Manangoi displayed some of his reputed 46 second (400) speed, running past his teammate and on to a 2 metre victory. Three metres behind, Mechaal made a serious move to try to get ahead of Ingebrigtsen, trying to pass in the narrow space on the inside. He got his shoulders as far as Ingebrigtsen's 10 metres prior to the finish but couldn't get by, both men struggling and falling toward the finish line. Ingebrigtsen leaned for the bronze medal position while Mechaal put his hand out onto Ingebrigtsen's back.

2017 World Championships in Athletics – Men's 20 kilometres walk, Summary

2017 World Championships in Athletics – Men's 4 × 100 metres relay, Summary

Their main challenger was expected to be USA which put their 2015 anchor, Mike Rodgers on leadoff, and scheduled the fastest starter in the championships, Christian Coleman to run against Bolt on anchor. Earlier in the day, Bolt did anchor the team to qualify, minus McLeod.


2017 World Championships in Athletics – Men's 4 × 100 metres relay, Summary
Out of the blocks, USA and Jamaica were out about even, making up the stagger on Stuart Dutamby for France to their outside. Great Britain with Chijindu Ujah and on the far outside, Shuhei Tada for Japan were also out with them. A good British handoff to Adam Gemili  had them passing China on their outside, while USA's 100 metre champion Justin Gatlin gained a step on Julian Forte for Jamaica. Into the third leg around the turn, USA's Jaylen Bacon maintained the lead against Jamaica's Yohan Blake, with Britain's Danny Talbot  also ahead of Jamaica.


2017 World Championships in Athletics – Men's 4 × 100 metres relay, Summary
Britain made a smooth blind handoff to Nethaneel Mitchell-Blake while Coleman took the baton off Bacon, Britain leaving the zone with a slight advantage, while Bolt had two metres to make up for Jamaica. Such a gain was expected to be within Bolt's ability but four steps into the straightaway, Bolt flinched in pain, hopping then somersaulting to the track. Mitchell-Blake and Coleman raced almost even until the last 20 metres when Mitchell-Blake pulled ahead and dipped at the finish line for an unexpected British win on home soil. 8 metres back, Japan came home with bronze, backing up their Olympic silver.


2017 World Championships in Athletics – Men's 4 × 100 metres relay, Summary
Medical aid with a wheelchair and his Jamaican teammates surrounded Bolt on the ground. While the British men's and women's relay teams celebrated together, Bolt lay on the ground in pain for a couple of minutes then refused the wheelchair and was helped to his feet by his teammates. With them by his side he limped across the finish line for the final time then went back to the ground wincing in pain. 100 Metre Champion Justin Gatlin blamed Bolt's injury on the poor planning and the teams being sent out forty-five minutes late.


2017 World Championships in Athletics – Men's 4 × 100 metres relay, Summary

2017 World Championships in Athletics – Men's 4 × 400 metres relay, Summary

Through most of the lap, Cherry held a five-metre lead while Cowan was challenging Cedenio. Cedenio held off Cowan then on the homestretch he separated, making a run at Cherry. USA passed to Fred Kerley barely a metre ahead of TTO's pass to Lalonde Gordon.

2017 World Championships in Athletics – Men's 50 kilometres walk, Summary
Four days before the event, three time World Championship medallist, Australia's Jared Tallent was forced to withdraw from the event due to a hamstring injury.


2017 World Championships in Athletics – Men's 50 kilometres walk, Summary
From the start, world record holder, 39 year old Yohann Diniz (FRA) walked with a sense of purpose. Save a silver medal in 2007, the World Championships had resulted in disqualifications and failure for him as had the Olympics. On this course in 2012, Diniz became disoriented and was left by the lead pack lying on the ground after he tripped over a barricade.


2017 World Championships in Athletics – Men's 50 kilometres walk, Summary
From the gun, Diniz walked at his own pace at the front of the pack. He had to make a quick, unplanned pit stop before the 5k mark which brought him back to the pack of some 20 competitors, but really only Horacio Nava (MEX) was able to stay with him for a short while. Again Diniz set sail solo and continued building his lead. 41 seconds at 10k, 1:32 at 15k, 2:10 at 20k, 2:59 by halfway. Reminiscent of last year's Olympics, would his huge lead evaporate into another catastrophe?


2017 World Championships in Athletics – Men's 50 kilometres walk, Summary
Chasing Diniz was a pack of podium suitors that stayed together with individuals falling off the back. By half way it was down to seven, with two Ecudorians; Claudio Villanueva and Andrés Chocho; two Japanese Hirooki Arai and Kai Kobayashi; Aleksi Ojala (FIN); Evan Dunfee (CAN); and Yu Wei (CHN). That group stayed together past 35k, where Diniz had a 4:21 lead. At 36k, the two Japanese teammates took off on their own. In the next 4k, they put 27 seconds on the next challenger Dunfee, while Chocho was disqualified for form violation and asked off the course.


2017 World Championships in Athletics – Men's 50 kilometres walk, Summary
Diniz did not suffer a catastrophe. By the last 2k loop, he had lapped everybody except four walkers. Like his world record three years earlier, Diniz spent the last lap celebrating; tying a French flag around his neck like a bandana, slapping hands with the spectators in the front row. He held the French flag above his head as he crossed the finish line. The two Japanese worked together to keep up the pace, the more experienced Arai finally taking a slight lead for silver, 8:05 behind Diniz. It was the second fastest 50k racewalk of all time, only behind Diniz' world record and the largest margin of victory in World Championship history.

This race was announced as the last track race of Mo Farah's career as he intends to focus on marathon running and road racing. Farah had been in every final since 2007, winning three straight since 2011.


2017 World Championships in Athletics – Men's 5000 metres, Summary
In the final, Farah (GBR) started faster than normal, after the pack congealed landing in second place behind Paul Chelimo (USA) who ran around the crowd to get to the front. Chelimo took the field through an aggressive 62 second lap. The second lap was a decidedly more relaxed 71 seconds, bringing Andrew Butchart (GBR) to the front, to look at Chelimo then take the point with his teammate Farah in tow. But Butchart didn't increase the pace, instead it slowed slightly to 72 seconds. Muktar Edris (ETH) came forward.


2017 World Championships in Athletics – Men's 5000 metres, Summary
After running shoulder to shoulder with Farah for 200 metres, Edris went out into the lead, but the pace didn't quicken.

Barega increased the pace opening up several metres on Farah at the head of the pack with a 65 second lap, then he slowed again an Ethiopian leaving Farah exposed on the front of the pack.

With five laps to go Patrick Tiernan ran around the field to take the lead. Tiernan moved the pace up to 64 seconds but the rest of the field didn't chase, letting him break away to a 10 metre lead. The next lap was under 63 seconds, with Yomif Kejelcha (ETH) coming to the front of the pack but leaving Farah to lead the group. Into the last two laps, a time when Farah does not like to get passed, he stayed ahead of Kejelcha, the overall quicken pace overtaking Tiernan with 600 metres to go.

Shortly after passing Tiernan, Butchart rushed forward to get on Farah's shoulder to form a British wall similar to the ending stages of the Olympics. Through the turn, Kejelcha fought his way around the outside of the wall and onto the homestretch to take the lead going into the bell with the rest of the Ethiopian team, Edris and Barega lining up on the outside, next to Farah, Mohammed Ahmed (CAN), and Chelimo on the inside. At the bell, Edris was shoulder to shoulder with Farah.

Through the penultimate turn, Edris got ahead of Farah and onto the back of Kejelcha. The two Ethiopians opened up a 2 metre lead on Farah on the backstretch, leaving Farah in the unfamiliar position of having to sprint to catch up. But Chelimo had more speed, catching Farah from behind and moving to his outside shoulder as they gained on the Ethiopian duo, effectively leaving Farah boxed in on the curb. Coming off the final turn, Farah was looking for running room, which suddenly materialized in front of him as Kejelcha drifted out.

Edris sprinted away from his teammate while Farah was still weaving his way past Kejelcha, with Chelimo going the outside route, both two metres behind Edris. Farah's race was for second place, with Edris expanding his lead to the finish. Farah was able to barely hold off Chelimo for silver. Unlike the spring in his step following his previous string of victories, it was Farah lying exhausted on the track.

As the final began, the runner with the fastest personal best, =#3 all time Nigel Amos (Botswana) ran a fast turn and was attempting to take the tangent from the break line in his lane 5, but Brandon McBride (Canada), ran a faster turn and cut more sharply from lane 7, effectively interrupting Amos from taking control of the early pace. Looking for running room Amos also cut in, tangling elbows with Kipyegon Bett (Kenya), then bouncing to the side, getting caught also behind Thiago André (Brazil). McBride held the lead with André in his shadow.

He went wider on the backstretch, running in lane 3 past the field, including the battling leaders, taking the lead unencumbered as they entered the final turn.
