The Yankees will honor Mariano Rivera, who is baseball's all-time saves leader with 652 career saves (and counting) today. Mo's number 42 has been painted onto the field and a number of ex-Yankees are expected to be in attendance, from Reggie Jackson to Bernie Williams.

The Yankees will also be wearing caps with a special patch to honor Rivera. According to cap-maker New Era, this is the first time an MLB team will be honoring an active player on its cap.
