Left-handers J.A. Happ (2-0, 2.60) and Ross Detwiler (0-0, 2.45) are set to pitch when the Phillies and Nationals begin a weekend set at 7:05.
Meanwhile, after seeking a second opinion, Brett Myers tells the Phiadelphia Inquirer that he will have surgery to repair a torn labrum in his hip, likely costing him the rest of the season. That means more pressure on one of the league's worst rotations to pick up the slack. It also places more emphasis on Happ to embrace his starting duties quickly. Happ pitched very well Saturday against the Yankees, but was under a pitch count after spending seven weeks as the Phillies longman. Longer outings will become even more crucial to preserving the bullpen now that the Phils have lost the season's steadiest arm. For Washington, Detwiler, Washington's first-round pick in 2007, makes his first career road start for the 13-33 Nationals. The Phillies enter play a half game off the pace of the Mets in the East.
