BOSTON (AP)- The Boston Red Sox placed right-handed reliever Vicente Padilla on the 15-day disabled list with arm tightness and promoted right-hander Clayton Mortensen from Triple-A Pawtucket before their game against Texas on Wednesday.
Padilla, who has provided a valuable late-inning set up role, is 4-1 with a 4.62 ERA in 41 games.
Mortensen returns to Boston for the fifth time. He's 1-0 with a 1.17 ERA in 10 games.
