can't use up your whole bench when it looks like it could go extras Why not? You dont have to worry about the pitcher hitting, and you essentially have all your best guys out there. move Edmonds to center, Kosuke to right, DeRosa to 2nd Soto to catch. if it turns into a marathon you will have guys getting 10 at-bats and playing the field all day. They will be tired for days. Plus you always have to keep someone back in case you have a injury. Would you want to have to throw one of pitchers in the field because Lou wanted a slightly better hitter in the 9th. Key being slightly if Fontenot is great and Reed is bad against righties then yeah I say go for it because you have to get to extras to have a chance.
