The Philadelphia Phillies have placed righty starting pitcher Roy Oswalt on the 15-day disabled list due to lower back tightness. Oswalt has pitched in 13 games (all starts) for the Phillies so far this year and he is 4-6 with a 3.79 ERA and a 1.33 WHIP. The Phillies will use rookie righty Vance Worley in Oswalt’s spot in the rotation. Worley has pitched in 8 games (6 starts) for the Phillies so far this year and he is 2-1 with a 2.83 ERA and a 1.40 WHIP. He should do a solid job while Oswalt is on the mend. The Phillies have called up righty reliever Scott Mathieson to take over Oswalt’s spot on the roster and he will work out of the bullpen. Mathieson has pitched in 2 games (0 starts) for the Phillies so far this year and he is 0-0 with a 0.00 ERA and a 2.33 WHIP.
UPDATE: (6/26/2011) – Oswalt may be out until August as he has a mild bulging disk that he doesn’t want to injure anymore than it already is.
