What It Means:

According to Derrick Goold of the St. Louis Post-Dispatch, it will be determined at the time of the procedure whether Schafer needs Tommy John surgery. He was forced to exit Sunday's game due to tightness in his forearm, which wound up being a significant injury. The 30-year-old left-hander had been in camp with the Cardinals as both a pitcher and outfielder.

Schafer made his first attempt on the mound in 2016, recording a 3.15 ERA, 1.45 WHIP and 25.6 strikeout percentage across 40 innings (31 games) for Double-A Tulsa (Dodgers).
