The thing is, both the As and the Mets think they can win it this year. Oakland has tremendous depth at SP (really, it's kind of rediculous), and the Mets have a big fat hole behind Pedro. If the As think they can win without Zito, they'll pull the trigger. Sure, the Mets can get Zito at the end of the year, but they need pitching help now if they're going to make a run at the WS before Delgado and Pedro atrophy too much.
