The Minnesota Twins have placed starter Kevin Slowey and reliever Ron Mahay on the disabled list after both were injured on Saturday against the Los Angeles Angels.

Slowey the 9-3 loss after three innings because of discomfort in his right triceps.

The Twins say Slowey will be further examined by doctors Monday. He gave up four runs on seven hits in three innings and said he felt a twinge in the muscle during the last hitter he faced.

Slowey needed 69 pitches to get through the three innings, one start after pitching seven no-hit innings against Oakland. Manager Ron Gardenhire pulled him from that game as a safety precaution because Slowey has had elbow tendinitis this season.

The lefty Mahay left the game in the sixth when he stumbled off the mound trying to field a dribbler form Erick Aybar. He says he strained his right shoulder while coming off the mound, then hurt it more when he fell to the ground.

The Twins recalled starter Nick Blackburn and reliever Anthony Slama from AAA Rochester to fill in. Gardenhire says it has yet to be determined when Blackburn will start next.

Minnesota entered play Saturday atop the American League Central standings with a 4 1/2-game lead over the Chicago White Sox.
