White Sox right-hander Matt Foster underwent Tommy John surgery this week, per Scott Merkin of MLB.com. The righty was placed on the 15-day injured list at the start of the season due to a forearm strain and was transferred to the 60-day last week.

Foster, 28, has spent his entire career with the White Sox thus far, having been selected by them in the 20th round of the 2016 draft. He worked his way up to the majors and debuted in 2020, showing promise that year by posting a 2.20 ERA in 28 2/3 innings. He struck out 28.4% of batters faced while walking 8.3% of them and got grounders on 35.8% of balls in play. He wasn’t quite able to maintain that pace in the two subsequent seasons, however, registering a combined 5.14 ERA in 84 innings with a diminished strikeout rate of 22.3%.

Foster will now be out of action for the remainder of this year and part of 2024 as well, given the typical Tommy John recovery time of 14 to 18 months. He’ll accrue a full year of service time while on the IL all season, which will get him beyond the three-year plateau and qualify him for arbitration for the first time in the coming offseason.
