Is it time to discuss the postseason roster?

With another win tonight, the Red Sox move ever closer to securing a playoff spot. And with that being the case, they will soon have to decide who is going to be on the roster. The starting nine, Mirabelli, Cora, the top four starters, and Pap/Okajima/Delcarmen/Timlin are a given, assuming health. That leaves six other spots to fill in. Loogy Lopez is probably in and Kielty too, leaving four more players. Who else gets in there? Does Lester or Tavarez make it as a reliever? Is Ellsbury a sure thing (I say yes)? Should Hinske get kicked to the curb? How would you fill out the rest of the roster?
