Bruce Bochy said yesterday that all five starting pitchers will make the Giants’ postseason roster. So barring something unforeseen, we won’t see the same situation as back in 2010 when Barry Zito was left off the playoff squad and had to contribute by being a good teammate (translation: not pouting).

That being said, not all five starters will start in the playoffs, at least not in the National League Division Series which should start at AT&T Park on Oct. 6 against either Cincinnati or Washington. Currently the Nationals have a half-game lead in the loss column and a 5-2 head-to-head record against the Reds, so there’s a better chance that the Giants face Cincinnati in the NLDS.

Which starter will become a long reliever? 

We can narrow it down pretty quickly since the top three starters will be Matt Cain, Tim Lincecum and Madison Bumgarner in some order. Cain — the unquestioned ace this year — will probably start Game 1, followed by Bumgarner in Game 2 since he has been so much more successful at home (2.38 ERA, 0.42 HR/9) than on the road (4.21 ERA, 1.46 HR/9), with Lincecum starting Game 3.

Game 4 is where it gets tricky. Ryan Vogelsong is coming off his best start in a month, while Zito has pitched well in some big games throughout the course of the season. Neither pitcher performed well in August, but Zito has been better in September.

Here is how each pitcher fared in 2012 against the Reds and Nationals:

Vogelsong vs. Cincinnati (4/26, 7/1): 13 IP, 4.15 ERA, 10 H, 10 K, 3 BB, 2 HR

Vogelsong vs. Washington (8/13): 2.2 IP, 27.00 ERA, 9 H, 5 K, 2 BB, 0 HR

Zito vs. Cincinnati (4/25, 6/30): 12 IP, 1.50 ERA, 10 H, 7 K, 8 BB, 1 HR

Zito vs. Washington: N/A

In looking at the Reds’ and Nationals’ splits vs. left-handed and right-handed starters, there is virtually no difference.
