MLB.com beat reporter Jenifer Langosch has the update, which can be considered promising news for the Cardinals and their ace …
Adam Wainwright, who disclosed after his Tuesday night start that he has been battling tendinitis for the past few weeks, returned to St. Louis on Wednesday to have an MRI on his right elbow.
The exam showed that the soreness is not the result of damage to the ligament, which was already replaced when Wainwright underwent Tommy John surgery in 2011. Instead, the Cardinals are describing the issue as similar to that of tennis elbow, a condition that can be caused by overuse and overextension of the elbow.
Wainwright was given a cortisone injection to help with the elbow discomfort. He has not been scratched yet from his next scheduled start — Monday night against the Mets — because the Cardinals’ medical staff wants to see his right elbow responds to the cortisone. A decision will be made Friday or Saturday.
Wainwright, 32, owns a 2.15 ERA and 0.927 WHIP through 14 starts this season for St. Louis.
He threw a whopping 276 2/3 innings last year between the regular season and playoffs.
