I must agree that Kuroda has less upside, but more stability than a lot of the pitchers on your roster, so I wouldn't drop him at all. Hard to take a gamble on Francisco at this point, but maybe Kendrick, Webb, Kazmir, or Marcum. I'm not sold on Kazmir or Marcum being great, and Kendrick always is a tough call, and Webb may not be back for a while. I don't think I'd drop anyone. I'd try to make a trade, I think to get RP help, but there are always closers available the further into the season you go to replace any closers.
