Are you really suggesting that the Twins can't find somebody to pitch every 5th day if they trade Santana? For starters, calling Berrios back up is long overdue. You've also got Jason Wheeler at AAA, and he could be worth a look. There's also the waiver wire. You could even put Andrew Albers in there. Doesn't matter. The point is that they're not playing for this year anymore, and probably not next year, either, so use those starts to get a look at somebody else, or just give them to anybody at this point. Get the best return you can for Santana under the circumstances and hope you end up with a player who can help in 2-3 years when you're (hopefully) contending again. Santana is not going to be that player, so why bother? That's the whole idea of being a seller at the trade deadline. And teams likely to lose 90-100 games should definitely be sellers.
