The Mets just announced they placed Mike Pelfrey on the DL after a MRI showed swelling in his elbow (retroactive to April 22). Taking his place on the roster is left-handed pitcher Robert Carson from Double-A Binghamton.
ESPN reported Pelfrey has a partial tear of the ulnar collateral ligament in his right elbow and could undergo season-ending surgery.
Pelfrey is expected to get a second opinion. Pelfrey was rocked in his first start, but pitched well in his last two.
Carson, 23, is 0-0 with a 3.18 ERA in five games at Binghamton.
