Minnesota Twins left-handed reliever Ron Mahay is out for the rest of the season with a torn right rotator cuff.

The Twins got better news on right-handed starter Kevin Slowey, out with a mild muscle strain in his right triceps.

An MRI revealed no significant damage, and manager Ron Gardenhire said Slowey would be back in the rotation in a couple of weeks.

Both pitchers were injured during Saturday's 9-3 loss to the Los Angeles Angels and were placed on the 15-day disabled list after the game.

Mahay was trying to field a ground ball in the sixth inning, but stumbled and fell awkwardly on his right shoulder.

The AL Central-leading Twins opened a four-game series against the Texas Rangers on Monday night.
