Curtis Granderson, who turns 32 in March, has played center field in the Bronx for each of the past three seasons. Putting balls in play is becoming a struggle for him and, when healthy, Brett Gardner is a superior defensive player. The New York Yankees aren't likely to re-sign Granderson after his contract expires this fall.
They obviously need a catcher after former backstop Russell Martin signed with the Pittsburgh Pirates.
Brian McCann underwent shoulder surgery in October that might keep him sidelined into April. When back at 100 percent, however, he'll make an awesome offensive impact. McCann maintained an .850 OPS from 2006-2011, which translated to six consecutive NL All-Star selections.
Jonny Venters could be even more valuable in the long run. He's under team control for another three years and is already established as an elite setup man. He would move up in the bullpen hierarchy if and when Mariano Rivera retires.
