Arizona Diamondbacks have put emphasis on the bullpen.
In 2022, one of the biggest issues the Diamondbacks had was with the depth of the bullpen. Arizona struggled to find quality guys who could come in and get outs. Because of that, they relied on starters to go deep into games, and often times would throw a starter out there one inning too long.
This season, Arizona has a plethora of young arms who can man the bullpen as they work their way into starting roles in the future. It is one thing to dominate minor league batters, getting major league batters out, is a whole nother story.
