NJ.com is reporting that an MRI revealed a partially-torn ulnar collateral ligament, per a source, and that the results were sent to notable surgeon Dr. James Andrews in Alabama. The Mets have only said Pelfrey is dealing with joint swelling and Pelrey told reporters Tuesday that his arm felt great. He was placed on the 15-day DL for the first time in his career on Tuesday.
If Pelfrey does have a badly-torn UCL, it could require Tommy John surgery, but the hope is that the swelling will go down and he can avoid surgery. Tommy John surgery would sideline Pelfrey for more than a year.
Pelrey has been a bright spot early in the season for the Mets. He has given up five earned runs on 24 hits over 19 2/3 innings. The Mets were 2-1 in his starts, although he didn't record a decision.
