Pence led the crowd in the team's "YES" celebration, in which the dugout celebrates home runs by moving up and down and pointing one finger to the sky. With Pence as their leader, the sellout crowd at AT&T Park did the chant in unison.
Manager Bruce Bochy joked that he took Pence out of Sunday's game early so that he could prepare a speech.
"Sometimes you don't know where he's going," Bochy quipped. "He loves it, has a lot of fun with it, and what a great job he did."
