Yankees manager Joe Girardi isn't ready to place the tag of designated hitter on longtime catcher Jorge Posada. Posada is currently the only member of the Core Four, which includes Derek Jeter, Andy Pettitte and Mariano Rivera, under contract for the 2011 season. He started just 78 games behind the plate this season, but Girardi says it's too early to decide Posada's role for 2011. "I think that's something that we have to discuss over the winter in how we construct our team and who we bring in or don't bring in," Girardi said. "That's something I'll have to think long and hard about."
