I say trade Colome.
Relief pitching is a fickle commodity. You have unknown guys coming out of nowhere to become dominant each year, and the markets won't get any hotter than during the regular season. You're going to get an inflated value out of relievers by contenders who just need that one extra arm to get themselves over the hump.
I think there are enough arms out there during the offseason that you can bring in a half dozen low-risk / high-upside guys and hope that one sticks.
