Baez has been diagnosed with a torn elbow ligament and will require Tommy John surgery, freelance writer Francys Romero reports.
Baez had recently been sidelined with arm fatigue and made only three appearances this spring, allowing four runs (three earned) and posting a 5:4 K:BB over 3.1 innings. He'll miss the entirety of the 2021 campaign and is likely to be out for part of 2022 as well.
