JaredAMuscat It's a legitimate concern. Right now, the Giants are dealing with two pitchers who are effectively halves of Jonathan Sanchez - one half has trouble throwing strikes, walks a lot of batters and is generally wild; the other is left handed.Zito has enchanted me like he has everyone else. His confidence is soaring through the heavens right now and it glowed in last night's outing. But we can't just dismiss his long, looooong history of mediocrity, not to mention the legitimate effectiveness of the Reds against LHP and the Nationals against everything Giant.The Giants beat the Padres in 2010 with Jonathan Sanchez, and then mortally wounded the Braves with him. But both starts were dicerolls, especially that one against the Padres. That pendulum swung back during the NLCS and World Series. The Giants don't have to take as many risks this season with Cain-Bumgarner as solid as they've been. If they use Zito, it has to be either in a low leverage game (up 2-0) or as a Hail Mary right before elimination.He really shouldn't start in the NLDS, if he's going to go it should be in the NLCS or World Series where the Giants could recover from a starter imploding. While it's generally tempting to want Zito to dominate the Reds as spiteful payback for the Reds bullying the Giants over the past few years, it's an unnecessary dangerous and not smart baseball.
