Edgin, a 25-year old lefty, has yet to make his major league debut after being drafted by the Atlanta Braves in the 50th round of the 2009 MLB Amateur Draft. He is 3-2 with a 3.89 ERA and 40 strikeouts in 37 innings over 35 appearances in Triple-A Buffalo this season.
Gee will undergo surgery Friday in St. Louis to replace a portion of damaged artery, and is expected to miss the remainder of the season. He was released from the hospital on Wednesday after being admitted for a blood clot in his right (pitching) shoulder. The surgery is designed to keep Gee from getting another similar blood clot in the future.
