The Arizona bullpen has been an Achilles’ heel for almost as long as Mike Hazen has been in charge. We’ve previously documented where Arizona’s relievers ranked in various areas: the team has been below major-league average, regardless of whether you look at ERA, FIP, xFIP or fWAR, every season since 2019. Last year, the team was in the bottom third by all four metrics. Given how narrowly they missed the post-season, it’s no exaggeration to say the bullpen cost the team a playoff spot last year. Nothing shows this more clearly than a 59% save percentage. That ranked the D-backs equal 26th: three of the four teams below them had the worst three records in the majors for 2024 (Rockies, Marlins and White Sox).
