Who would of thought the toughest match of Andy Murray and Novak Djokovic's career would be at a girl's birthday party? Probably nobody, but HEAD Tennis is making that a reality in their latest commercial spot.

The two tennis stars teamed up with major tennis brand on their latest ad campaign that finds the two squaring off in the toughest match of their careers, all while entertaining a spoiled girls birthday party. Murray and Djokovic are currently involved in another "ultimate match" as they are both still in contention for the 2014 French Open title, which neither has won in their storied career.

Check out the new campaign spot, and go over to HEAD for an opportunity to win either a Graphene Radical or Speed Racquet signed by Andy or Novak.
