CLEVELAND — Indians closer Joe Borowski was placed on the 15-day disabled list today, a day after blowing a save and giving up a two-run homer in the ninth inning to Boston's Manny Ramirez in a 6-4 loss to the Red Sox.

The club said Borowski, who led the AL with 45 saves last season, has a strained triceps. He had been puzzled and frustrated by a significant loss in his velocity.

The club recalled right-hander Tom Mastny from Triple-A Buffalo.

With Borowski out, Indians manager Eric Wedge likely will turn to Rafael Betancourt as his new closer. Betancourt was one of baseball's top set-up men last season. He had three saves last season and has 12 career saves.
