SAN DIEGO — Adam Rosales singled in the tying run before Santiago Casilla balked home the winning run, and the San Diego Padres rallied to beat the major league-leading San Francisco Giants 7-6 on Saturday night.
The Padres started the decisive rally when Alex Dickerson and Derek Norris singled to open the 10th against Casilla. Norris stole second before Rosales bounced a single past shortstop Brandon Crawford to tie the game.
With Alexei Ramirez at the plate, Casilla stumbled during his delivery and a balk was called, bringing in Norris with the winning run.
Kevin Quackenbush won despite giving up Buster Posey’s go-ahead, opposite-field homer leading off the 10th, the Giants’ fourth home run of the night.
Posey hit a 91 mph fastball to right field for his 12th homer this season.
San Diego twice had three-run leads, both of which evaporated after Giants home runs.
Angel Pagan hit a two-run shot off rookie starter Luis Perdomo in the third to pull San Francisco to 3-2.
Pinch-hitter Mac Williamson and Ramiro Pena homered off Carlos Villanueva to tie the game at 5 in the sixth. It was Williamson’s fourth and Pena’s first.
San Diego had the bases loaded and one out in the seventh and failed to score.
The Padres led 5-2 after three innings against Jeff Samardzija, thanks to home runs by rookie Ryan Schimpf and Matt Kemp, and two errors.
Schimpf homered leading off the second, his fifth, and hit an RBI triple in the third. Kemp homered leading off the third, his 17th, and Schimpf hit an RBI triple with two outs.
Samardzija walked his first two batters. Travis Jankowski stole third and Posey threw the ball into left field for an error that brought in a run. Yangervis Solarte singled with one out to make it 2-0.
Samardzija allowed five runs, four earned, and five hits in five innings. He struck out four and walked four.
