San Francisco Giants manager Bruce Bochy has been contemplating who to use as his designated hitter when the World Series shifts to Detroit for Game 3 on Saturday (8 p.m. ET).

A pitcher has not been among them. Maybe one should.

Entering Game 2 on Thursday night, San Francisco was the first team to have a pitcher with an RBI in four consecutive games in the same post-season.

'Pitchers can just help themselves in different ways ... find a way to get a bunt down or even drive in a run. I mean, they're part of the offence, too.' — Giants manager Bruce Bochy, who may use a pitcher at DH for Game 3

Barry Zito, who batted .075 with only two runs batted in all season, has a pair during the current streak, including an opposite-field RBI single to left off Justin Verlander in the fourth inning of Game 1.

That streak ended in San Francisco's 2-0 win in Game 2.

"It's been huge," Bochy said. "Pitchers can just help themselves in different ways, whether it's hold runners, fielding their position or find a way to get a bunt down or even drive in a run. I mean, they're part of the offence, too."

Bochy has been leaning toward backup catcher Hector Sanchez to DH for Game 3. He already has said he plans to have all-star Buster Posey catch every game.

Bochy could also have Pablo Sandoval DH and shift slick-fielding Joaquin Arias to third. Aubrey Huff and Ryan Theriot are also options at designated hitter.

Since interleague play began in 1997, the American League has a 2,081-1,883 record against the National League in the regular season. The last time the NL won the season series was in 2003. The AL is 8-7 in the World Series during that same span.

Through Game 1, the NL is 24-19 in its home parks during the World Series since 1997. The AL is 27-11 in its home park in the Series during that time.

Detroit has had to put designated hitter Delmon Young in left field in San Francisco. Andy Dirks and Quintin Berry split time in left most of the season.

"I think it's different for your pitcher not only in that he's pitching a game, but now that those moments that he takes underneath to sit and relax between innings, now he's hitting," Tigers manager Jim Leyland said.
