The Diamondbacks used 41 different pitchers this year. That far and away blows past the previous high of 30, set in 2018, and is more than twice the number used in four seasons, most recently 2008 with twenty. Indeed, this would have been a new all-time record for the National League, as the most through the end of 2020 was 37. That was most recently achieved by the Marlins in that 2020 campaign - yep, despite there being only sixty games played that year. But this season, a full 40% of the National League, six teams, used 38 or more pitchers.
