The Yankees pitchers and catchers, along with Curtis Granderson, Derek Jeter, and a few other fellows, are out stretching and running and jogging and all the fun things you do when you’re at spring training. (Though it was actually in the high 40s most of the day in Tampa, if that makes you feel better.) To celebrate baseball’s reemergence from hibernation, we scoured our Baseball Prospectus 2010 book yesterday, and gleaned the following insights on the Yankees: The stats show Robinson Cano is as lousy a clutch hitter as you remember; Austin Jackson was traded at the exact right time; Jeter ages unlike almost any shortstop in baseball history; Jesus Montero should be in the lineup sooner rather than later; Damaso Marte will be excellent this year; and, in the book’s most controversial prediction, Mariano Rivera will be awesome. Tomorrow, on the day their own pitchers and catchers report, the Mets are our B-Pro focus. Until then, enjoy footage of baseball players who are only slightly less cold than you.
