Washington's Alfonso Soriano smacks a double. Soriano also scored two runs in the Nationals' 10-7 win on Monday.

After Lowry’s one-out single in the second, Astacio retired the next nine Giants before Winn singled in the fifth. Vizquel followed with a triple, then scored on Ray Durham’s single. Durham drove in another run in the eighth.

Barry Bonds went 0-for-4 with a walk and flied out to deep center to end the eighth with two runners on.

Lowry (5-7), facing Washington in consecutive starts after getting a no-decision last Wednesday, allowed six runs and eight hits in five innings.

“Obviously I wanted to go out there today and get the team out of this funk,” Lowry said. “I let our guys down.”

Relievers Brian Wilson and Steve Kline had their problems in the eighth, too.

“We’re 4½ games out and this is the worst baseball we’ve played all year,” Kline said. “Everybody here wants to win. Nobody wants to pack it in. You can see tempers are flaring and guys are getting antsy.”

Nationals catcher Robert Fick left the game in the seventh with left rib cartilage separation and was scheduled for an MRI on Tuesday.

San Francisco right fielder Moises Alou was ejected by plate umpire Brian Gorman after he struck out looking to end the third inning. He tossed his bat all the way to the Giants’ dugout, then threw down his batting helmet in disgust. Gorman tossed Alou, who then yelled at the umpire for several moments before leaving.
