SAN FRANCISCO -- Barry Zito and his bat earned the Giants pitching staff a place in the record book Wednesday night.

Overshadowed by Pablo Sandoval's monster night, Zito delivered a fourth-inning single that made it four consecutive postseason games in which a San Francisco pitcher drove in a run -- a first for any team in baseball history.

Hitting, starting pitcher Ryan Vogelsong said, is something the staff works hard at under the direction of coach Tim Flannery.

"You'd be surprised how many times it helps you win games, bunting guys over, starting rallies," said Vogelsong, whose contribution to the streak came in Game 6 of the National League Championship Series against the St. Louis Cardinals. "It's something you have to do in the National League."

Zito started the streak in Game 5 of the NCLS, and Vogelsong and Matt Cain continued it.

With Brandon Belt on second base Wednesday night, Zito singled to left field just past Detroit Tigers third baseman Miguel Cabrera, who might have been expecting a bunt after Zito bunted for a hit in the NLCS.

All part of the plan, reliever Jeremy Affeldt said.

"When you have to play up for a bunt like that and then he threw the bat out there, you take away the range," Affeldt said. "A ball could drop, and it did."

Belt said the other eight players in the lineup can be inspired when a pitcher comes through at the plate.

"It's fun to watch that, and I think it gets a little energy in there," he said. "We don't want to be undone by pitchers, so we've got to try and go up there and get our hits, as well."

Zito's RBI was the first by a pitcher in Game 1 of the World Series since 1969, when the Baltimore Orioles' Mike Cuellar drove in a run against the New York Mets.

  • Marco Scutaro went 2 for 4 to run his postseason hit streak to 11 consecutive games. That ties the Giants franchise record set by Irish Meusel, who did it for New York over the 1921 and '22 World Series.

    "It seems like Scutaro's getting a hit every time he's up," catcher Buster Posey said of the NLCS MVP.

  • With Hector Sanchez likely to see time as a designated hitter, the Giants considered adding Eli Whiteside to the World Series roster as a third catcher.

    But manager Bruce Bochy elected to keep the same 25-man roster for the third consecutive round, saying third baseman and former catcher Sandoval will serve as an emergency catcher.

    Bochy said he anticipates Posey being the starting catcher for every game of the series regardless of the starting pitcher.

  • Sandoval is donating a bat to the Baseball Hall of Fame in Cooperstown, N.Y. He used the bat for the first two of his three homers on the night before breaking it.

  • The only-in-the-Bay-Area trio of Joe Montana, MC Hammer and San Francisco Mayor Ed Lee were sitting together and drew a big cheer when their faces appeared on the stadium video board.

  • The winner of Game 1 has gone on to win the World Series 66 times (61.7 percent). It's been the case in eight of the past nine and 13 of the past 15 World Series.

  • Since 1993, every home team to win Game 1 has gone on to win the World Series. Those teams: 1993 Blue Jays, 1995 Braves, 1997 Marlins, 1998 Yankees, 2000 Yankees, 2001 Diamondbacks, 2004 Red Sox, 2005 White Sox, 2007 Red Sox, 2010 Giants and 2011 Cardinals.

  • Home-plate umpire Gerry Davis was on the field for his 112th postseason game, the most of any umpire in history.
