Rest-of-Season Projections
2023 Fantasy Outlook
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. Read Past Outlooks

Scheduled to pitch Friday
Bummer (lat) is scheduled to appear in Friday's Cactus League game against the Athletics, Scott Merkin of MLB.com reports.
ANALYSIS
Bummer will be making his Cactus League debut against Oakland after missing the start of spring training with soreness in his right lat. The right-hander isn't a lock to make the Opening Day roster because of how much time he'll have missed, but his stint on the injured list would likely be short if he isn't available for the start of the season. Bummer could be in line for save chances for the White Sox at some point in 2023 with no defined closer for Chicago to begin the campaign.

2018
Bummer proved that his small-sample spike in strikeouts in 2020 wasn't a fluke, as he was once again able to top a 30 K% in 2021 across 56.1 innings. Even better was that he didn't sacrifice his primary identity as a groundball pitcher by turning in his third consecutive season with a groundball rate over 65%. Unsurprisingly, that has helped him limit home runs, and he's been able to limit hitters to 0.6 HR/9 across 187 career innings. In most cases, that combination of skills would lead to a pitcher receiving a look as closer, though Bummer has largely been limited to a setup role throughout his career. That isn't likely to change in 2022, as the White Sox boast a tremendous trio in the back of their bullpen in Liam Hendriks, Craig Kimbrel and Kendall Graveman. While we expect Kimbrel to get dealt at some point later in the offseason, Bummer's value is still likely tied to his strong ratios and plenty of strikeouts.
