Would you drop any of these players for Aviles?

Oh, wow. If Contreras is your best pitcher, you know you have things going well. But out of these guys, I'd drop Rafael Soriano. He's on the DL right now, and I don't trust him when he comes back. Usually when a pitcher comes back from the DL because of shoulder problems, they take awhile before they pitch like they did before. And since your pitching seems very solid, dropping Soriano won't hurt you too much for now.
