I really don't think bullpen upgrades were available in June as there were next to no trades made at all for the entire month. Prices were already stupidly high at the deadline, I shudder to think what the cost for relief upgrades would have been prior to the deadline this season. I actually like the bench quite a bit right now. Having Biggio, Tapia, Merrifield, and Kirk when he's not catching/DH that day is actually pretty decent, especially compared to previous years. When everyone is healthy the rotation is 6 deep. Of course this depends on Kikuchi actually contributing something, but his first few starts after returning from the IL have been pretty encouraging.
