Kopech (shoulder) underwent surgery on his right knee Thursday, James Fegan of The Athletic reports.
Kopech was already likely to miss the rest of the 2022 season due to a shoulder injury. That's now official, and he'll end the campaign with a 3.54 ERA, 1.19 WHIP and 105:57 K:BB across 119.1 frames. Kopech is expected to overcome both issues in time to pitch without limitations for the beginning of spring training in 2023.
