The Mets released Marcum on Tuesday after receiving confirmation that Marcum was unlikely to pitch again this season.
Mets starter Shaun Marcum began the 2013 season with what was diagnosed as right shoulder impingement syndrome, and his season ended this week with another type of impingement — that of the Thoracic Outlet.
Mets assistant general manager John Ricco said Marcum was diagnosed with Thoracic Outlet syndrome, a condition that involves the compression of nerves near the neck.
John Ricco said before Monday night’s game in San Francisco that Jonathon Niese has been cleared to start throwing again. Shaun Marcum, however, had his right hand examined by a specialist in St. Louis and will miss his next scheduled start Saturday.
Andrew Brown hit a two-run single with two outs in the 13th inning and the Mets put together a pair of late rallies to hand the NL West-leading Diamondbacks their fourth straight loss, 5-4 on Monday.

David Wright has taken over the lead in the voting to be the starting third baseman for the National League All-Star team. Wright has also been hot at the plate, going 4-for-5 with two doubles, a triple and a home run in the Mets’ 8-0 win over the Phillies on Sunday.
