Marmol can't be our closer. Reason being, he can pitch possibly 2 innings for us and get us out of a huge jam (which is what he's done the entire year and 1/4 he's been here). If he was our closer and we are in jam before the 9th, who are we going to use to KNOW we can get out of it? Wood is just going to have to get more comfortable in this role.
It'd also make more sense to give Lee the day off tomorrow, so he gets an extra day. Why would you give him a day off, then play him, then get another day off? Hopefully two days in a row of nothing will get his mind in the right state.
