The Marlins stocked up on a lot, and they're playing well despite the fact that their best pitcher has been ridiculously shaky. Hate to agree with Jacko, but your characterization of the Sox's chances are gratuitously overconfident. You should have learned your lesson with that promise that the Red Sox would make the playoffs to not let your mouth/keyboard write checks that your ass can't cash.
That said, I still think the Sox will get hot, and make the playoffs with about 95 wins, and the Marlins will only win about 83 or 84 tops. Even if and when JJ gets into a groove, I don't see Zambrano being this good, he might have a solid comeback year, but he's going to fall off. I don't know though, baseball is weird.
