SAN FRANCISCO -- The San Francisco Giants suddenly have the slightest bit of momentum at home -- and that was something to celebrate, even for a brief moment.
Rich Aurilia lined a go-ahead two-run double to center field in the eighth inning, Bengie Molina had another big night and the Giants rallied to beat the Washington Nationals 6-4 on Wednesday.
"This gives us a lot of confidence that we can do it again," Molina said. "Games like this get your confidence back up and make you believe you can win games. The beauty of the Western Division is that even though we've played so bad the last couple of weeks, we're still in it."
Aurilia came up big with an eight-pitch at-bat in which he fouled off three straight pitches before the double. Omar Vizquel gave the Giants an insurance run with an RBI double off Luis Ayala (1-6) on the heels of Aurilia's hit and had his third three-hit game this season.
Geno Espineli (1-0) recorded two outs in the eighth for his first major league victory and the Giants won consecutive home games for the first time since June 1-2 against San Diego and the New York Mets. Brian Wilson pitched the ninth for his NL-leading 27th save in 29 chances and 18th in a row.
San Francisco came back after Nationals pinch-hitter Johnny Estrada hit a go-ahead RBI single in the sixth, the same inning in which Jesus Flores hit a tying two-run homer for Washington.
"It's a great feeling and it does so much for a club. It's something you can build on," Giants manager Bruce Bochy said. "It's nice to win a series here."
Molina provided the Giants' clutch hits for the second straight game, getting two RBI doubles after his two-homer game a night earlier.
The Giants are still searching for ways to win at home. San Francisco ended a four-game home losing streak Tuesday night and has only six victories in the last 20 games in the club's waterfront ballpark.
