Are you sure about that? The Yankees have to re-sign Jeter, who's a FA, after this season. Are the Phillies going to re-sign Werth? He's a FA in 2011, too.
The Yanks will definitely go after Lee regardless of Jeter's next big signing. When the hell did the Yanks start worrying about their payroll? I'd like the Phils to resign Werth but I'm not 100% convinced it's going to happen. Although, I'm not entirely impressed with Dominic Brown right now. Stranger things have happened.
