In general, how do you guys feel about late inning player swaps, specifically to put in solid D guys? Forget last night, I'm talking in general terms.
My gut response to them has been "if the guy can't be counted on to make a play in the 9th, why is he in the game in the 5th?". A game could be lost in an earlier inning because of a defensive screw up could it not? Also, I don't care for taking out offensive power to shore up the D in later innings because if you go into extended innings you have less "power bats" who can win the game in one swing.
OTOH, If a guy swings a big bat but has defensive issues I guess I can see why you'd want to take advantage of his bat in the early innings while removing his errors in the late innings when you have less outs to overcome the mistake. A serrious defensive lapse could lose the game in one swing also.
But I still lean towards the idea that if you can't trust a guy in the 9th, you shouldn't trust him the other 8 innings either.
