The 2014 U.S. Open is underway! And to celebrate Titleist being the #1 ball played at the U.S. Open for 66 years (and still counting), we wanted to have a little fun with our latest Team Titleist Trivia sweepstakes.

We've pulled together another great prize pack and here is what four lucky Team Titleist members will win... 

>> Two (2) dozen Pro V1 or Pro V1x golf balls with choice of personalization and custom play number (00, 1-9 or 10-99)

>> One (1) limited edition Team Titleist performance fabric hat (white or navy) or Tour Visor

>> One Team Titleist bag tag

So how do you enter? Here is the trivia question...

TRIVIA QUESTION: Correctly identify all of the Titleist Brand Ambassadors and Golf Ball loyalists that autographed the golf balls pictured above (click on the image above for a larger view and close-ups).

Hint... Every player is in the field at the 2014 U.S. Open and they all play either a Titleist Pro V1 or Pro V1x golf ball.
