SAN FRANCISCO, Sept. 3 (UPI) -- Marco Scuarto drove in Brandon Crawford with a game-winning, 10th-inning single Monday, rallying San Francisco to a 9-8 victory over Arizona.

Crawford singled to lead off the 10th against Bryan Shaw (1-5), went to second on Brett Pill's sacrifice and to third on Angel Pagan's groundout.

That brought up Scutaro, who scalded a 3-1 pitch past diving third baseman Chris Johnson and down the left field line, scoring the game-winning run.

The Giants -- who trailed 7-4 after six innings -- had forced an extra frame in the ninth when Scutaro (3-for-5) doubled and scored on Buster Posey's two-bagger off Diamondbacks closer J.J. Putz.

Posey finished with two RBI while Pablo Sandoval went 3-for-5 and knocked in a run for the National League West-leading Giants, who took the opener of a three-game series.

Sergio Romo (4-2) earned the victory with a 1-2-3 top of the 10th.

Johnson smacked a two-run homer and added a sacrifice fly during a five-run sixth inning for the D-backs.
