For some reason that whole "I didn't say I was going to be stupid" comment rubbed me the wrong way. I would say some of the things Yost has done this season have been stupid. I have no statistics to back this up, but it is purely my own opinion. I'd think it would be easier for a borderline guy (eg: Spurling, Aquino, McClung, etc.) to pitch with a lead late in a game than to pitch when the game is tied and they might feel like they have to be "perfect" to not lose the game. It might not make that much of a difference in the way they pitch, but it has to add a little bit of pressure on the home team, knowing they would be down to their last 3 outs. Also, as far as confidence goes, by using your best reliever first you are giving your offense a chance and telling them you believe in them by virtually saying "we're going to hold this game, now get us the lead." Obviously every situation doesn't call for using your closer before a save situation, but I think facing the heart of the Astros order is a situation that would definitely call for it.
