Jake Peavy walked into the cramped visiting clubhouse at Wrigley Field shortly after batting practice and announced that the teams would play two on Thursday. Travis Ishikawa's head dropped.

"My first thought was, 'Gosh, did we get rained out?' " Ishikawa said.

It was all clear a night after a controversial rain delay, and the Giants sailed to an easy 8-3 win after finding out that a successful protest had temporarily wiped Tuesday's loss off the books. As the news spread, the Giants gave themselves a shot to leave Chicago with three wins. The now-suspended game will be completed before Thursday's scheduled contest.

Ishikawa, in his second tour with the franchise, had three hits, including two RBI doubles. Peavy pitched seven resilient innings, saving a bullpen that will have to work overtime Thursday. The Giants had 14 hits and scored seven runs in the first three innings while knocking out erratic Cubs right-hander Edwin Jackson.

"A good club lets what happened the previous day go," Peavy said. "You can't play with revenge on your mind."

Peavy put Tuesday's fiasco in the past, but not completely. He knew he needed to go deep to give the bullpen a chance Thursday, when they'll face the Cubs lineup for at least 12 innings.

"We have a long day tomorrow and a lot of innings to play, so it was nice for Jake to get deep into the game," manager Bruce Bochy said. "That's a gutty effort."

Peavy viewed it as an incomplete one.
