Minnesota Twins starting pitcher P.J. Walters had to leave Wednesday night's 9-8 loss against the Philadelphia Phillies due to stiffness in his right shoulder. Walters only lasted through part of the first inning while throwing only 15 pitches, and during that brief time he was in the game he gave up four hits and four runs.
After Thursday's MRI, Walters had been placed on the 15-day disabled list for having inflammation in his right shoulder.
With Walters now on the disabled list, the Twins recalled right-handed pitcher Lester Oliveros who has been pitching in Class AAA Rochester. Oliveros has pitched 12 games at Triple-A this season and he has gone 1-1 with a 4.08 ERA, with four saves and 22 strikeouts in 17.2 innings.
