What: Game 2 of The 2009 World Series
Where: Yankee Stadium, New York City
Complex says: Jay and Alicia Keys were supposed to kick off Game 1 of the World Series, but weather conditions forced them to reschedule. No matter, both were still in top form as they performed Jay's only No. 1 hit, which also served as Derek Jeter's entrance music. The performance proved once again that Jay—who rocked Timbs and was not in all-black everything—made the Yankee's hat more famous than A-Rod ever could.
