Hunter Pence had three hits, including a solo homer, scored three times and knocked in two Sunday to lead the San Francisco Giants to an 8-2 win over the Arizona Diamondbacks.
Buster Posey also had three hits and drove in two and Hector Sanchez knocked in three for the Giants, who took two out of three in the series. They had nine hits and scored five runs off Arizona starter Patrick Corbin (13-5).
Yusmeiro Petit, who won his first start of the season Tuesday at Colorado, made it two in a row for the Giants. Petit (2-0) struck out 10 in seven-plus innings, giving up two runs on seven hits and a walk.
"That's another great start for him in two tough ballparks," said Giants manager Bruce Bochy. "He had great command, hit his spots and mixed it up. He's got some savvy out there. He knows what he's doing."
Corbin gave up eight earned runs in 5 1/3 innings at Philadelphia last Sunday and wasn't much better in his next start. He allowed nine hits and a walk in five innings, striking out six, and is 1-4 in his last seven starts.
"I just wasn't able to locate anything," said Corbin. "I left some pitches up."
