The 2019 Arizona Diamondbacks season was the franchise's 21st season in Major League Baseball and their 21st season at Chase Field in Phoenix, Arizona as members of the National League West. They were managed by Torey Lovullo in his third season with the franchise.
The 2019 Diamondbacks were the first team in Major League history to have their road opener against one reigning pennant winner (Dodgers) and their home opener against the other (Red Sox) in the same season. Despite improving upon their 82–80 record from last season, the Diamondbacks were eliminated from postseason contention for the second consecutive year after a loss to the Cardinals on September 23.
The 2019 Diamondbacks were by one measure the "most average team" in baseball history. For 60 games, the Diamondbacks were within two games of .500 (plus or minus), an MLB record that surpassed a 56-game streak by the 2007 Oakland Athletics. The stretch lasted from June 18, when the Diamondbacks lost to the Colorado Rockies to fall to 38–36, through August 30, when they beat the Los Angeles Dodgers to improve to 69–66.
The Diamondbacks broke a league record alongside the Philadelphia Phillies this season for most home runs in one game, smashing a franchise record 8 home runs out of 13 total in a 13–8 win on June 10.Real or not? This home run thing has gotten out of hand Additionally, the Diamondbacks set a franchise record on September 24/25, when their game against the Cardinals lasted 19 innings, the longest game by innings played in Diamondbacks' history and, at 6 hours and 53 minutes from start to finish, the longest game ever played at Chase Field. Having used 30 players in this game, the Diamondbacks set another franchise record in that respect, and, with 25 strikeouts by Diamondbacks pitchers and 21 by Cardinals pitchers, both teams tied a Major League Baseball record for most strikeouts in a single game at 46, the game also marking only the second time in baseball history that two teams struck out 21 or more opponents in the same game. The Diamondbacks won the game, 3–2. To date, this is the most recent “two for one” 18+ inning game in regular season MLB play.
