What happened: The Yankees reinstated Rivera as a right-handed pitcher and utility player before Saturday’s alumni game. He will wear No. 42 at the 78th Old-Timers’ Day.

Why it matters: The signature song accompanied Rivera’s entrances during his years as New York’s closer. His appearance restores a familiar centerpiece to the annual reunion.

What to watch: Traditional alumni introductions will precede the game at Yankee Stadium.
