"He probably would tell me he could give us an inning tomorrow, but I'll stay away from him," Bochy said Sunday.
Petit, who bounced between roles as a long reliever and spot starter during the regular season, allowed just one hit and struck out seven in six shutout innings Saturday.
• After playing an 18-inning affair that was the longest postseason game in Major League history, Bochy canceled the Giants' workout at AT&T Park on Sunday.
"I gave them a day off, and I really didn't want them to come to the park," Bochy said. "Just get a break. They played 18 innings. Plus, we played in Pittsburgh. I mean, that was a road trip that we were on."
• The Giants have won two of the last four World Series titles, but they've only clinched one of those six postseason series (2012 NL Championship Series against the Cardinals] at AT&T Park. They have the opportunity to add a second home celebration Monday.
"It's going to be a little different tomorrow [at AT&T Park], and these guys know it, from 2010 and 2012," Bochy said Sunday. "I know they are looking forward to coming out here."
