Report: Mets' Herrera facing elbow surgery

New York Mets left-handed relief pitcher Daniel Herrera reportedly will undergo Tommy John surgery.

The team's doctors found a tear in Herrera's left elbow, ESPNNewYork.com reported Friday.

Herrera, 27, has not pitched in the majors this season, throwing in three games for Triple-A Buffalo with a 1.50 ERA. He pitched in 16 games for the Mets last season after he was the play-to-be-named in the Francisco Rodriguez trade with the Milwaukee Brewers.
