DeGrom (shoulder) was diagnosed with a stress reaction in his right scapula and will be shut down from throwing for four weeks, Anthony DiComo of MLB.com reports.

EDGE Analysis

The right-hander will obviously miss Opening Day and is set to be re-evaluated after a month. DeGrom appeared to enter spring training healthy after battling elbow issues last season, but the stress reaction will instead cost him a significant portion of the 2022 campaign. Even if the 33-year-old starts throwing again immediately after the four-week shutdown, he'll likely be sidelined for at least another month as he builds up his arm strength. Tylor Megill should be the favorite for the vacant rotation spot to begin the season, though David Peterson figures to also be in the mix.
