Bummer had one of his worst statistical seasons over his seven-year career in 2023. His 6.79 ERA was highest in the league among qualified relievers, while his 1.53 WHIP was 12th-worst. This is mostly due to an elevated 13.5% walk rate (his worst since his rookie season), high BABIP (.340) and poor 55.4% left-on-base percentage. However, Bummer's inflated ERA was far worse than his 3.58 xERA, suggesting he should rebound in that category. The veteran is still one of the best in the league at inducing ground balls, but Bummer threw fewer sinkers (45% pitch usage) last season in favor of more sweepers (38%). This adjustment yielded a career-high 78 strikeouts, which speaks to the upside the southpaw possesses. Bummer was recently traded to Atlanta, where he could emerge as one of the team's top setup options in 2024. Read Past Outlooks
