That's fine, but then when are you going to use Cuas to begin with? It's the mid-portion of the game, you *dont* have the bases loaded, and you have a hitter who is far worst against RHP. As I said in another post, this is the *exact* situation you have Cuas for, someone who is a designed righty-killer.
We can ask a bigger question of "is Cuas the guy you want in that role?" But once you make the choice to roster Cuas...this is when you are going to use him.
