Well, weve finally gotten the answer to the question that has nagged for nearly two weeks: Your Game Four and Five starters for the San Francisco Giants are . . .Not as important as we thought.Oh, sure, Tim Lincecum is important, and getting the ball for the Giants in Game 4 of the National League Championship Series creates with it a few tweaks to a lineup that needs all the tweaks its skin can endure. And Barry Zito is certainly an interesting notion for Game 5, insofar as it means that Madison Bumgarner is out, at least for the moment.In other words, Hector Sanchez catches, which means Buster Posey goes to first base, which means Brandon Belt sits and, more likely than not, Hunter Pence moves down a spot in the lineup to break out of what has become the teams most noticeable slump.But as Bruce Bochy picked at his food in the Managers office after Wednesdays rain-engorged 3-1 win by the St. Louis Cardinals, he knew what the real problem is. And though he couldnt say it aloud, he could think it.He doesnt have enough difference-making players.Melky Cabrera is being missed, not so much in left field but certainly in the three-hole in the batting order. And Pablo Sandoval isnt hurting the team all that much in the three-hole, but he is a better five-hole hitter. And Pence, who is a better sixth-place hitter, is stuck in the five-spot unless Bochy decides that semi-desperate times call for semi-desperate measures.This all matters because the Cardinals, unlike the Cincinnati Reds before them, have decided that Buster Posey is not to see a hittable pitch in this series. Period. And there is no second Posey in the order to make the Cardinals think otherwise.This is a long-standing Cardinal philosophy the other guys best player is not to be the instrument of your death. It was a staple of Tony La Russas managing and Dave Duncans pitching philosophies, and it remains so with Mike Matheny and Derek Lilliquist.They dont walk him outright, although he had two Wednesday night. But they give him so little to work with because (a) they have no fear of Pence, Belt or Gregor Blanco behind Posey, (b) the bases are not crowded when Posey bats, and (c) hes seen eight different pitchers in three games, none more than twice in situations where he was actually allowed to hit.In short, St. Louis is ahead in this series, two games to one, in significant part because they dont believe the Giants have enough hitting to force them to pitch to Posey.In Game 1, he batted once with a runner in scoring position and Joe Kelly walked him. In Game 2, he batted once with a runner scoring position again, in the bottom of the eighth with the Giants already ahead, 6-4, and was struck out by Marc Rzepcynski in a what-the-hell situation. And in Game 3, his one chance with a runner in scoring position ended in another walk, from Kyle Lohse.You may not remember it because, well, it was before the rain delay.The point is, in sum, that while we have exercised our mighty brains wondering about the level of Marco Scutaros health, the relative darkness of Matt Hollidays soul, the identities of the Giants fourth and fifth starters and the whereabouts of Pence, the Cardinals have been making the Giants beat them without their best hitter in play.And except for the fourth inning of Game 1, the fourth and eighth innings of Game 2 and the third inning Wednesday, they havent.So, while it is invigorating in some sense to know that Lincecum and Zito are pitching games Four and Five and Madison Bumgarner is being reduced to a role as the new Lincecum, the real issue is offense, and more specifically which player or combination of players is going to force the Cardinals to break programming and face Posey in a difficult situation.In other words, Lincecum can do a lot of things, but he cant win a game with Matt Cains run support levels, and neither can Zito for that matter. Pitching will not save the Giants if they cant solve the more fundamental problem. Losing 2-1, 6-1, or 11-1 is the same thing when youre the guy packing the 1.And while it seems like every day presents a different reason why Bochy picks at his postgame meal and curses the events of the day, so much of it has to do with one thing.The Cardinals have not been forced to face Buster Posey straight up. Until they are, all the other nuances of the series will be rendered moot.
