Right-handed reliever Stephen Pryor has been placed on the 15-day disabled list by the Seattle Mariners after he suffered a tear in a muscle in his back.
Seattle made the move on Monday, the Mariners' first off day of the season. Seattle said a corresponding roster move would be made on Tuesday prior to the opening of a series against Detroit.
Pryor left Sunday's game against Texas with two outs in the eighth inning. He was preliminarily diagnosed with discomfort in the muscle, but was reevaluated on Monday when the tear was discovered. It's another injury hit for the Mariners who already have put starting outfielder Michael Saunders on the disabled list and had injuries problems with Michael Morse and Franklin Gutierrez.
Pryor had appeared in seven of 14 games this season and not allowed a run in 7 1-3 innings pitched.
