NEW YORK - Caroline Wozniacki suffered a bad hair day at the US Open on Wednesday when her flowing blonde ponytail became trapped in the frame of her tennis racquet. The incident happened as the former world number one chased down a shot from Belarusian opponent Aliaksandra Sasnovich during her 6-3, 6-4 victory on the Grandstand court. As the Dane went into her backswing, her braided hair became tangled in the racquet. “It used to happen when I didn’t braid my hair. That’s why I started braiding it. Once it gets to a certain length sometimes it can get stuck in the arm or the racquet. It’s a first, you know, when it’s braided that it’s been stuck that good in my racquet,” said the 2009 finalist. “I still tried to hit the ball. Almost took my head off.”–AFP
