For the third time in the history of the rivalry (the previous two were 1930 and 1992), both teams had new managers to start the 2018 season. The Yankees hired Aaron Boone and the Red Sox hired Alex Cora, both former players of their respective teams. During an early-season game, a brawl erupted between both benches after Yankees first baseman Tyler Austin charged Red Sox pitcher Joe Kelly for throwing at him twice in response to Austin's slide at second base earlier in the game. It became a trending topic on Twitter and the MLB's YouTube channel video of the incident became one of the most viewed, and social media commentators saw the brawl as a spark of a reignited rivalry between the two teams. By the end of the 2018 regular season, both teams qualified for the postseason and both reached the 100-win mark. It was the first time that both teams won at least 100 games in the same season and, along with the Houston Astros, the first time the American League had three 100-game winners. Following the Yankees' victory in the AL Wild Card Game, the two faced each other in the 2018 ALDS. The Red Sox won the series 3–1, taking Games 3 and 4 in Yankee Stadium by a combined score of 20-4. Just like in the April brawl, this series became a Twitter trending topic.
