Mike Adams has likely thrown his last pitch of 2013.

An examination Tuesday revealed three tears in his shoulder — two in his labrum and one in his rotator cuff — that could require surgery. Adams said he has not yet decided to undergo the procedure or attempt a non-surgical route, but either way, the injuries will probably end his season.

"It's not good," Adams said.

Adams, 34, was signed by the Phillies to a two-year, $12 million deal last winter. He was hailed as a cure for the team's eighth-inning woes in 2012. He posted a 3.96 ERA in 28 games and pitched through back and shoulder injuries.

He underwent rib surgery last winter to correct thoracic outlet syndrome, which caused numbness in his right arm and shoulder. Adams has a history of shoulder problems; he tore his labrum in 2008. Adams was examined by Neal ElAttrache, the Los Angeles Dodgers physician.
