Orioles place Bud Norris on DL with groin injury
The move is retroactive to June 22.
Norris left his start last Saturday, a 6-1 win over the New York Yankees, after five innings when he felt tightness in his groin after throwing a fastball.
After throwing a bullpen session on Wednesday, Norris was scratched from his scheduled Friday start.
Norris (7-5) has won his last four starts, and has a 3.62 ERA to go along with 60 strikeouts and a 1.16 WHIP this season for the Orioles, who come into this weekend's series against the Tampa Bay Rays two games behind the Toronto Blue Jays in the American League East.
