Rich Aurilia lined a go-ahead two-run double in the eighth inning and the San Francisco Giants rallied to beat the Washington Nationals 6-4 on Wednesday night.

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 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.
