New York Mets closer Bobby Parnell has decided to undergo Tommy John surgery, the team announced Sunday night. The team said he would undergo the surgery Tuesday, at the Hospital for Special Surgery in New York. Mets Medical Director Dr. David Altchek will perform the procedure, the team said.

Parnell complained about tightness in his right forearm after the Mets' home opener last Monday, during which he blew a one-run Mets lead in the ninth inning. He underwent an MRI, and was diagnosed with a partially torn medial collateral ligament in his elbow. After placing Parnell on the disabled list, the Mets originally said he would rest for two weeks before a decision was made on surgery.

With Parnell out, 36-year-old Jose Valverde is expected to take over the bulk of the closer duties. In 3.1 innings so far this season, Valverde hasn't allowed a run and has struck out six. He earned a save in the Mets' 4-3 win over the Cincinnati Reds on Friday.

Parnell's appearance last Monday was his first since July 30, and his first game back after undergoing surgery late last year to treat a herniated disc. Parnell had a 2.16 ERA, 1.00 WHIP and 44 strikeouts in 50 innings last season. He converted 22 saves in 26 appearances before being placed on the DL.
