Mets Right-Hander Shaun Marcum Faces Season-Ending Surgery

New York Mets right-hander Shaun Marcum faces season-ending surgery on a blocked artery that is impeding blood flow to his hand, Assistant General Manager John Ricco said.

Marcum was diagnosed with thoracic outlet syndrome after he complained of tingling and numbness in his right hand. He will have surgery July 15.

“It involves an artery that’s blocking circulation,” Ricco said on the team’s website. “They go in and do a procedure that frees up the blood flow.”

Ricco said Marcum, who is 1-10 with a 5.29 earned-run average, may be ready to throw again in early September.

“I don’t think there would be enough time for him to get back to the big leagues,” Ricco said.

Right-handed reliever Gonzalez Germen from Triple-A Las Vegas was activated for last night’s game against the San Francisco Giants, taking Marcum’s roster spot.
