About those white-billed caps ...

NEW YORK -- So why are the Yankees wearing nontraditional white-billed caps?

During the pregame ceremony on Friday, the Yankees announced to the crowd: "New Era is the official on-field cap of Major League Baseball and has been a part of MLB history since 1930. On July 21st, the New Era Cap Company hosted the 11th Annual David C. Koch Memorial Gala and Golf Tournament to raise money for the University of Pittsburgh Cancer Institute in order to raise awareness and help prevent cancer.

"Tonight, in honor of this, the New York Yankees will be wearing the New Era Diamond Era On-Field Batting Practice 59Fifty Cap for the game. In recognition of its long-standing partnership with both the Koch family and New Era and their fight against cancer, tonight the New York Yankees are also pleased to donate $10,000 to the David C. Koch Foundation."

New Era is a major sponsor of the Yankees, and together the two sponsor the New Era Pinstripe Bowl played at Yankee Stadium.

The only player spotted not wearing the white-billed hat and opting for tradition was none other than Derek Jeter.

The Yankees have worn the hats before, during spring training.
