SAN FRANCISCO — Yonder Alonso's two-run single in the seventh inning snapped a tie and helped the San Diego Padres beat the San Francisco Giants 6-4 on Sunday.
Mark Kotsay hit a home run and Yasmani Grandal also drove in a run for the Padres, who had lost four of their previous five games. Everth Cabrera had four hits, walked and stole three bases in five plate appearances.
Xavier Nady, who had two hits, Eli Whiteside, Emmanuel Burriss and Buster Posey each drove in runs for the Giants, who rested their regulars a day after clinching the NL West Division title.
Eric Stults (7-3) worked six-plus innings, allowing three runs on seven hits, to win his sixth in seven decisions. He struck out four and walked one.
Yusmeiro Petit made his Giants' debut, allowing two runs on seven hits over 4 2/3 innings. He walked four and struck out one.
Clay Hensley (4-4) took the loss after giving up Alonso's hit.
Huston Street pitched the ninth for his first save since Aug. 10, his 22nd of the season and 200th of his career. His scoreless streak ended at 21 2/3 innings.
It wasn't easy.
Pinch hitter Aubrey Huff singled to lead off the ninth. Street got pinch hitter Pablo Sandoval to fly out to right but then walked pinch hitter Hunter Pence and Hector Sanchez to load the bases. Posey grounded out, driving in his 98th run of the season before Ryan Theriot lined out to center field to end it.
Petit made his first major league since Sept. 6, 2009 when he was with the Arizona Diamondbacks as the Giants had their six-game win streak and seven-game home win streak stopped.
The Padres scored their first run in the second when Theriot threw the ball into left field trying to catch Alexi Amarista off second base following a sacrifice fly.
Nady doubled home a run and Whiteside hit a sacrifice fly to put the Giants up 2-1 in the fourth.
Grandal's single tied it in the fifth and Alonso's hit put San Diego ahead in the seventh.
Burriss hit an infield grounder to score a run in the seventh.
Kotsay hit his pinch hit home run in the eighth. Cabrera followed with a walk, stole second and third and jogged home when Hector Sanchez's throw went into left field.
