It looks like Charlie Manuel has decided to go with Joe Blanton tomorrow in Game 4. It may very well be the right call, but I don't think I'd make it. Given the way the Phils offense is performing, I expect very little from it tomorrow against a tough lefty, Madison Baumgartner. Joe Blanton (4.72 ERA) is a slightly below-average major league starter who is almost never dominant. This is what happens when you have average velocity, slightly above-average location, and below-average movement. The Phillies can't afford a run-of-the-mill barely-quality start tomorrow (which is a good day for Joe Blanton). They need a big, big start. They paid Roy Halladay to be the ace, they're built to win now, and he needs to be on the hill to save the season. A loss tomorrow would pit the Phils against Tim Lincecum in Game 5 (at home) in an elimination game. This scenario is worth taking a gamble to avoid.
I've heard the argument that starting Halladay tomorrow would force Oswalt and Hamels to pitch on 3 days rest as well. So what. Oswalt has done it before with success and Hamels hardly threw out his arm today (6 IP). It's the postseason, they're all veterans, and they can handle it.
If the season is to end at the hands of the Giants, then let it be because they beat the best we have. Don't let this run stop prematurely because the Giants were able to beat Joe Blanton, who by the way, hasn't pitched in 3 weeks.
