Knuckleballer Gamboa suspended 50 games


BALTIMORE -- Triple-A knuckleballer Eddie Gamboa received a 50-game suspension without pay on Friday after testing positive for exogenous testosterone, a performance-enhancing substance in violation of the Minor League Drug Prevention and Treatment Program.

"There's a lot of sidebars to this stuff," said manager Buck Showalter. "Still is what it is, a violation of the policy set down by baseball. Obviously I know a lot more about [the suspension]. Gamby was on the radar here, so it's unfortunate."

Gamboa, who was slated to pitch for Norfolk on Friday, will serve the suspension immediately. The O's also released knuckleballer Zach Clark, who -- like Gamboa -- converted to a knuckleball last season. Clark appeared in one game for the Orioles in 2013.

Gamboa, 29, is 4-5 with a 4.06 ERA in 14 games (12 starts) this season. He was second in the International League with 74 strikeouts in 77 2/3 innings.
