Gee was hospitalized Tuesday with numbness in the fingers of his right hand, and a subsequent angiogram revealed a clot in a right shoulder artery. With uncertainty surrounding Gee and his availability going forward, Edgin's big league debut could serve somewhat as an audition for a bullpen spot in the second half.
Edgin, 25, wasn't selected until the 30th round of the 2010 First-Year Player Draft, but he quickly impressed with an organizational-best 27 saves in 2011. He entered this season as the Mets' 20th ranked prospect according to MLB.com and wasted no time jumping from Double-A Binghamton to Buffalo.
The southpaw converted two saves and posted a 1.42 ERA in six games with Binghamton and was 3-2 with a 3.89 ERA in 35 appearances with Buffalo. He also notched 40 strikeouts in 37 innings of work at the Triple-A level.
Edgin, a 2011 South Atlantic League All-Star while with Class A Savannah, tossed 10 1/3 scoreless innings for the Mets during Spring Training this season, but he didn't break camp with the team. The southpaw didn't factor into a decision during the Grapefruit League, but he recorded two saves while striking out 13 and walking three.
