Derek Jeter, Jorge Posada and Mariano Rivera have been teammates on the Yankees for 16 years. Can you imagine playing on the same team as someone for that long?

Andy Pettitte has been on the Yankees for most of those years (he played for the Astros for three seasons).

The Yankees have won the World Series five times so far when the "Core Four" were on the team. Do you think the Yankees will win the championship again this year?
