Padres left-handed reliever Jose Castillo will undergo Tommy John surgery, Kevin Acee of the San Diego Union-Tribune reports. This isn’t surprising news, as Castillo exited a sim game Tuesday with forearm tightness.
The 2021 campaign will go down as another injury-ruined season for Castillo, who threw only two-thirds of an inning in 2019 while dealing with a teres major strain and didn’t pitch in 2020 because of a flexor strain and a torn ligament in his hand. Considering the time it takes to recover from TJ procedures, the 25-year-old Castillo won’t take a major league mound again until sometime in 2022, and that’s if he doesn’t suffer any setbacks. He’ll be eligible for arbitration for the first time next winter.
While the Padres look like one of the majors’ best teams heading into this season, the loss of Castillo is at least a blow to their bullpen depth. A healthy Castillo could have made the team all the more formidable, as he recorded excellent numbers during his rookie year in 2018. He threw 38 1/3 innings then and put up a 3.29 ERA/2.53 SIERA with an eye-popping 34.7 percent strikeout rate.
