2018 Colorado Rockies season

The 2018 Colorado Rockies season was the franchise's 26th in Major League Baseball and the 24th season the Rockies played their home games at Coors Field. Bud Black returned for his second consecutive season as manager. They won 91 games during the regular season, which was the second-highest mark in franchise history and just one win behind the franchise record set in 2009. They finished the season with a record of 91–71 after losing to the Los Angeles Dodgers in the NL West tie-breaker and subsequently opened the postseason by defeating the Chicago Cubs in the NLWC Game. Their season ended when they were swept by the Milwaukee Brewers in the NLDS.

The Rockies became the first team since the 1922 Philadelphia Phillies to play in four cities against four teams in five days, including the 162nd game of the regular season, NL West tie-breaker, NLWC Game and NLDS Game 1. They also finished with the best road record in franchise history, going 44-38 away from Coors Field.
