CLEVELAND — The Indians couldn't wait any longer for RHP Justin Masterson to fix his pitching problems.
The Indians placed Masterson on the 15-day disabled list with inflammation in his right knee Tuesday. Masterson, the team's opening day starter, is 4-6 with a 5.51 ERA.
Manager Terry Francona talked with Masterson on Monday after he allowed five runs and six hits in two-plus innings against the Yankees.
"Masty's first inclination was wanting to pitch through it, which we respect," Francona said. "The way it was going, though, we thought we'd DL him and get him some treatment."
Masterson made the All-Star team last season, when he had a 3.45 ERA and a career-best 195 strikeouts. The Indians considered him to be their staff ace going into the season, but Masterson has struggled from the start and has pitched more than four innings once in his past five starts.
