Right-hand pitcher Bobby Parnell has chosen to undergo Tommy John surgery after being diagnosed with a partially torn medial collateral ligament in his elbow, the New York Mets have confirmed.
The 29-year-old pitched for one inning on Opening Day, allowing one run and blowing the save for the Mets. He clearly didn't look right after many of his fastballs were classified as changeups.
Originally, Parnell had planned to enter rehab to treat the injury but the team have subsequently changed their mind.
It will be the second time Parnell has gone under the knife in under six months after being treated for a herniated disc in his neck back in December - something that held him back from spring training.
Parnell pitched 50 innings in 49 games last season and achieved stats of 2.16 ERA (166 ERA+) with a 3.67 K/BB, saving 22 games in the process.
Jose Valverde is the favourite to take over as the closer for the Mets.
