Big inning, bullpen boost Padres 05/03/2007 12:55 AM ET By Corey Brock / MLB.com SAN DIEGO -- The Padres were shorthanded Wednesday, but certainly not short on runs, as they scored five in the fourth inning en route to a 7-3 victory over the Nationals at PETCO Park. The news wasn't all good for the Padres, though, as pitcher Clay Hensley left the game in the third inning after straining his right groin. Hensley broke from the mound to cover first base on a foul ball hit toward the right side by Washington leadoff hitter Felipe Lopez. Hensley tried to stay in the game, taking a warmup pitch before wincing in pain. He then left the game and was replaced by Doug Brocail. It's not known if the right-hander will make his next scheduled start Tuesday in Atlanta. The Padres (15-13) enjoyed their big inning Wednesday at the expense of Nationals starter Matt Chico (2-3). San Diego scored its runs in the fourth on a Khalil Greene RBI triple, a Geoff Blum RBI bloop single, a Kevin Kouzmanoff sacrifice fly and a two-run double by Marcus Giles. Adrian Gonzalez added a home run, his eighth, in the eighth inning. Pinch-hitter Terrmel Sledge later had an RBI double in the frame. The Nationals (9-19) scored a run in the first inning on Ryan Church's single and then two more in the seventh inning on Kory Casto's double. Brocail, the pitcher who followed Hensley, tossed two scoreless innings to improve to 2-0 this season. ____________________________________________________ During the post-game conference, Bud Black said it doesnt look good. It looks like Clay Hensley is off to the DL. Tim Stauffer is on the DL at Portland. Mike Thompson has been pitching badly since returning to Portland. We're guessing they will call up Justin Germano.
