Do you need the roster spots? I'd keep Madson at least a couple more weeks to see who ends up being the closer for the Phillies down the stretch. If you've been holding on to Adams I'd also definitely wait until the MLB trading deadline to see if he moves to a closer role or not. If he gets traded to be a setup man then yes, drop him. It looks as if Axford will remain closer so that's a tough drop but might be one you need to make.
