2024 Fantasy Outlook
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
Nabs win Monday
Bummer (1-1) was credited with the win Monday against the Astros, giving up one hit in a scoreless two-thirds of an inning.
ANALYSIS
The left-hander got the final out of the fifth inning after relieving Darius Vines, and the official scorer elected to give Bummer the win. It's the earliest in a game he's pitched so far this season, but Bummer has been deployed anywhere from the fifth to the ninth inning as a utility arm in the Atlanta bullpen. Through six innings and seven appearances, he's posted a 4.50 ERA, 1.67 WHIP and 5:2 K:BB with zero holds or saves.

Latest Fantasy Rumors
Staying put
Bummer won't be traded at this year's deadline, Bob Nightengale of USA Today reports.
ANALYSIS
Teams keep asking about Dylan Cease and Bummer, but the White Sox will be keeping both pitchers in the fold. With Kendall Graveman and Reynaldo Lopez out of the picture and Keynan Middleton also likely to be dealt, it will be Bummer and Gregory Santos handling the high-leverage work while closer Liam Hendriks is on the shelf with an elbow issue.

Past Fantasy Outlooks

2022
2021
2020
2019
2018
Bummer required two IL stints in 2022, first a minimum stay early in the season for a sore knee, then a more lengthy 3-month absence due to a shoulder/lat injury. This limited the southpaw to only 26.2 innings last season. Injuries appear to be part of the package for the 29-year-old, who has now missed time on the IL during each of the past three years. When healthy, Bummer is adept at inducing ground balls, as his career rate is 67.6%, which is roughly 25% above league average. He walks about four batters per nine innings, though, and the frequent grounders could lead to some BABIP and ratio instability. However, Bummer's role as one of the White Sox primary setup men appears secure, so expect him to provide holds as long as he's healthy.
