Holliday gained his second NL Player of the Week selection of the season and fourth of his career on September 16, after hitting six home runs, driving in 11, batting .407 with a .500 on-base percentage, and leading the NL each with a 1.148 slugging percentage, 11 runs scored, and 31 total bases. In a 12-game span from September 9–20, he hit 11 home runs; only Alex Rodríguez matched that feat in 2007. One of the home runs was the 100th of his career and his 200th hit of the season, occurring on September 19 in a 9–8 victory over the Dodgers. His September totals included a .367 batting average, 29 runs scored, six doubles, 12 home runs, 30 RBI, and .796 slugging percentage, prompting MLB to award him NL Player of the Month honors as the Rockies won 13 of their 14 final scheduled games. He garnered copious attention for the Most Valuable Player (MVP) award throughout the season, which increased even more that September.
