ATHENS, Greece - Two players on the Greek Olympic baseball team tested positive for banned substances and were thrown off the team.

Andrew James Brack and Derek Nicholson, both U.S.-born Greek citizens, tested positive in samples taken Aug. 5, the Greek Olympic Committee said Monday.

“That we are talking about doping is very sad,” said Yiannis Papadoyiannakis, head of the Greek team.

Brack tested positive for the steroid stanozolol, while Nicholson, an alternate on the team, tested positive for diuretics, officials said.

Nicholson was a center fielder last season for the Toledo Mud Hens, the Detroit Tigers’ Triple-A team. Brack used to play in the independent Northeast League.
