PHILADELPHIA (AP) -- Alfonso Soriano isn't a typical leadoff hitter. He's just a productive one.
Livan Hernandez (4-5) pitched seven solid innings, allowing two runs and five hits to get his third straight win. Mike Stanton struck out Chase Utley, Bobby Abreu and Ryan Howard in the eighth, and Chad Cordero finished for his eighth save in 10 chances.
"Soriano gave us a spark," manager Frank Robinson said. "It seems when he does things, we win the game."
"We had a lot of opportunities and came up short," Rowand said. "We just have to go out there, put together some rallies and string together some hits."
Hernandez hit a one-out single in the third, before Soriano launched his 19th homer into the seats in left-center to put Washington ahead 2-1.
Soriano is batting .338 (48-for-142) with 13 homers and 26 RBI in the 34 games when he has batted first in the lineup. He's hitting just .220 (17-for-77) with six homers and 12 RBI in the 19 games he's been in the middle of the order.
"I got the big hit, but Livan pitched a great game," Soriano said.
Dellucci tied it at 2 with a shot to right field leading off the fifth. Hernandez escaped further trouble in the inning by retiring Jimmy Rollins on a double-play grounder with runners on first and third and one out.
The Phillies have lost seven straight one-run games since beating Cincinnati in extra innings on May 14. Overall, they're 7-11 in one-run games.
"We couldn't get the big hit at the right time," manager Charlie Manuel said. "We had chances but couldn't get it done. We were a hit away from winning the game."
Rowand gave the Phillies a 1-0 lead in the second inning with his seventh homer. After he froze on a breaking ball, Rowand stayed back and hit another off-speed pitch into the left-field seats.
Nationals center fielder Marlon Byrd made an outstanding catch in the fourth inning, leaping to rob Abreu of a homer.
Lidle gave up three runs and seven hits in 6 1/3 innings. He hasn't allowed fewer than three runs in any of his 11 starts.
Hernandez has lowered his ERA from 6.52 to 5.10 in his last four outings. He's pitched at least seven innings in each of those starts and hasn't given up more than three earned runs in any.
"I've changed my mechanics and my knee was bothering me earlier in the season," Hernandez said.
