Only here at AT&T Park could a sellout crowd stand and go hoarse at the sight of a 60-82 pitcher taking the mound for a 76-86 team on the final day of the regular season.

Barry Zito’s final bow was just one dramatic act on a day of high theater that will keep Giants fans counting the days till pitchers and catchers report next spring.

There was tragedy as Gregor Blanco sustained a potentially serious leg injury with two outs in the ninth inning. There was suspense when his replacement Francisco Peguero tied the game with his first big league home run in the bottom of the inning.

And there was the best kind of curtain when Hunter Pence the Giants’ new $90 million man lashed a bases-loaded walk-off single to finish with 99 RBIs and give the Giants a 7-6 victory a 76-86 record and a share of third place in the NL West.

“We have what no other team in baseball has” manager Bruce Bochy told the crowd. “It’s not even close. … And I promise you we will work hard this offseason to bring a championship back here."
