You can't plan for everything to go this perfectly though. A few of these games could've gone a different direction and we need them to eat the innings. Say last night, if Hall gives up a hit and they get down 3-4 runs or whatever it would've been. Well, then you're using the guys listed to keep everyone else fresh for today. I know Patrick was up earlier in the game too. And tonight, its possible Hall and Uribe are both marked as out tonight. All of a sudden you need those guys
In addition, I don't see how having Lockridge sit the bench would be any different than these Ps being ready if needed. The extra C is the only debate, so we're talking about 1-2 PAs extra for Sanchez vs the insurance of having fresh arms. Look what happened to the Pads vs us and what Cle/Sox went through last series, you need the arms if needed.
In a weird way, not having Naylor might've won last night's game. Perhaps they Sanchez and his good splits over Bauer last night if they didn't have to save their C
