The Chicago White Sox are already heading into the beginning of the 2022 MLB season with injuries. Most recently, Garrett Crochet suffered a season-ending elbow injury. According to a preliminary MRI reading, he is expected to need Tommy John surgery.

MLB columnist Bob Nightengale tweeted the news Friday afternoon.

The serious injury more than likely requires Tommy John surgery that will cost him the entire season. The procedure, also known as ulnar collateral ligament reconstruction, is performed by replacing a torn UCL with another tendon in the body (per Johns Hopkins Medicine).

This is a huge blow for the White Sox, a team already reworking its bullpen ahead of the regular season. Earlier Friday afternoon, news broke that the White Sox traded Craig Kimbrel to the Los Angeles Dodgers. In exchange, Chicago received outfielder AJ Pollock.

Although Pollock is a great addition to any MLB roster, he can’t fill the vacancy left behind by two pitchers.

Kimbrel joined the White Sox in July of 2021 and played less than a season for Chicago. In 63 games, Kimbrel pitched for 59.2 innings. He had an ERA of 2.26 with 100 strikeouts during his short stint in Chicago.

Meanwhile, Crochet was the White Sox’s 11th overall pick in the 2020 MLB Draft. The 22-year-old pitched in 54 games for a total of 54.1 innings last season. Crochet had an ERA of 2.82 and recorded 65 strikeouts in the regular season. He pitched five games in this year’s spring training preseason before suffering the injury.
