yes the likely need for pitching is what happened with Backe, the astros absolutely cannot afford to let the game go 5-0 after 2 innings and then a) leave him in or b) let the bullpen go for the rest of the day. also the fact that clemens, who knows hundred percent about hamstring as well as andy, possibly back in the minds of everybody is his elbow, and to have two guys who can get you long relief effort is at a premium for us. The only person who is trustworthy with finishing out the game would be oswalt.
IMHO, it isn't the idea that we played an 18 inning game, but the idea that our bullpen will be sucked dry and we have nothing left that dictated the situation for astacio... That is why sanders getting hot at this moment was a bad situation for us. if he was cold as ice, probably Scott might be on the roster...
