The New York Yankees may have a major concern with the health of their ace, reigning AL Cy Young award winner Gerrit Cole.

Manager Aaron Boone told reporters Monday morning that Cole has had trouble recovering from his starts this spring and will need to get an MRI on his pitching elbow.

Many pitchers will go through what's called a "dead arm" period during spring training, which is typically a result of ramping up the process of regaining stamina to get ready for the regular season.

However, Boone's comments seem to indicate there might be more to Cole's situation.

Cole, 33, went 15-4 with a 2.63 ERA and 222 strikeouts last season for the Yankees in winning his first Cy Young award.
