Being at the game, I don't really have a problem with any of the moves. I think sometimes Phil's a little too conservative with catchers, keeping Munson in at first, which meant taking out Scott, but Lamb's already on the bench, Biggio's already on the bench, and Bruntlett's in Round Rock. There's no other emergency catcher should one be needed. I don't think the switches that brought Lane and Ensberg can be faulted, being that Phil was trying to take advantage of opportunities to put an end to the game much earlier.
I hope I don't sound too much like an apologist. On that front, I'll go ahead and say he should have let Miller pitch the 8th with the two lefties starting off, then brought Wheeler in for the 9th. Having Lidge pitch the 9th is about the only obviously objectionable move he made, and maybe part of that comes from above. Finally he's taking a stand on Lidge. No more in 1-run games (is kinda how I read "bullpen by committee").
