White Sox right-hander Miguel Gonzalez underwent right shoulder surgery and will require a recovery period of nine to 12 months, the team announced tonight. Per the announcement, doctors “performed a labral repair and debridement” on Gonzalez.

It’s a tough blow for the 34-year-old Gonzalez, who made just three starts and totaled just 12 1/3 innings in what is now an injury-ruined season. He’d performed nicely with the Sox in 45 starts from 2016-17, pitching to a 4.02 ERA with 6.0 K/9 against 2.8 BB/9 in 268 2/3 innings before being traded over to the Rangers at the end of August. Gonzalez’s time with Texas didn’t go well, and he ultimately returned to the ChiSox on a one-year pact this offseason.

Gonzalez now, in a best-case scenario, wouldn’t be ready until mid-April of 2019, though the operation could effectively wipe out the first half of the 2019 season for the veteran right-hander as well. He’ll likely generate some minor league offers if not over the winter than early in the ’19 season as teams look to add veteran depth options to their organizations. In 883 2/3 innings between the O’s, White Sox and Rangers, Gonzalez has a 4.06 ERA with 6.3 K/9 against 2.9 BB/9.
