2021 Arizona Diamondbacks season
The 2021 Arizona Diamondbacks season was their 23rd season in Major League Baseball and also 23rd season at Chase Field in Phoenix, Arizona as members of the National League West. They were managed by Torey Lovullo in his fifth season with the franchise.
The Diamondbacks suffered a massive losing skid over 45 games from the 29th game against the Marlins to the 73rd game against the Dodgers that saw them only win 5 games that plunged their record from a 15–13 start to a 20–53 record including a franchise record 17-game losing streak. On June 17, 2021, with a 10–3 loss to the Giants, the team broke a dubious record of most consecutive road losses in the modern era, with 23. The MLB record was previously held by the 1943 Philadelphia Athletics and the 1963 New York Mets. One day later, they set a franchise record with their fifteenth consecutive loss, home or away. That streak would end at 17.
On August 14, 2021, Tyler Gilbert threw the third no-hitter in Diamondbacks history. This was his first Major League start, and the second no-hitter thrown at Chase Field. The Diamondbacks finished the 2021 season in fifth place in the National League West, with a 52–110 record, one game shy of tying their franchise-worst 2004 season, 51–111.
