New York Mets pitcher Johan Santana could miss the entire 2013 season after an MRI revealed a probable re-tear of his pitching shoulder, general manager Sandy Alderson told reporters on a conference call Thursday.

Santana already had surgery on the same shoulder in September 2010, and Alderson told reporters that a second surgery is a "strong possibility," according to ESPN New York's Adam Rubin.

Santana missed the entire 2011 season after undergoing the first procedure. He returned last season and had success in the first half of the year, including when he pitched the first no-hitter in Mets history last June. But he faded down the stretch, going 0-5 in July and August and putting up a 16.33 ERA after the All-Star break before he was placed on the disabled list.
