San Francisco manager Bruce Bochy plans to start a pair of 16-game winners in the first two games of the National League division series, but says he's not certain what he'll do beyond that.

Matt Cain will pitch Game 1 against the Cincinnati Reds on Saturday and left-hander Madison Bumgarner will go in Game 2 on Sunday. The two tied for the team lead in victories and were instrumental down the stretch when San Francisco won the NL West for the second time in three years.

Two-time Cy Young winner Tim Lincecum and 15-game winner Barry Zito have also been key for the Giants. But Bochy said Thursday he's unsure whether he'll use the two in starting roles or out of the bullpen. That goes for Ryan Vogelsong as well.
