Because if Nomar Garciaparra hadn't (and he just upped with Oakland a few days ago), a certain team from New York, who just lost their third baseman until mid-May, might be sniffing around, kicking his tires.
Granted Nomar isn't nearly the player he once was, but I never want to see him in pinstripes.
UPDATE: Now it turns out that the Yankees and Slappy will NOT go the surgery route for his hip, and that he will try to rehab and play with the injury. It's a similar injury that happened to Mike Lowell last year. And if what happened to Lowell last year is any indication, the Yankees better go out and get a replacement for Slappy. Right now.
