SAN DIEGO — All-Star Buster Posey drove in a season-high five runs and Chad Gaudin and three relievers combined on a five-hitter, leading the San Francisco Giants to a 10-1 victory against the San Diego Padres on Friday night.
Posey's two-run double highlighted San Francisco's five-run seventh inning, when Padres manager Bud Black was ejected for arguing an obstruction call during a rundown.
Marco Scutaro and Brandon Crawford had three hits apiece while Gregor Blanco scored four runs for the Giants, who won consecutive games for the first time since they beat San Diego June 18-19 at San Francisco. Coming in, the defending World Series champions had lost 16 of 20.
The Padres lost for the 17th time in 20 games and dropped a season-high 12 games under .500.
Black was ejected by second base umpire Laz Diaz for arguing after Kensuke Tanaka was awarded third base on an obstruction call against third baseman Chase Headley. Tanaka was on the infield grass when he and Headley collided.
