Are you kookoo for Coco? Coco Vandeweghe is an 18-year-old American who made a splash at the 2010 Mercury Life Insurance Open. There, the qualifier knocked off Wimbledon finalist Vera Zvonareva 2-6, 7-5, 6-4 in the second round. Alas, Vandeweghe - the niece of former NBA player Kiki Vandeweghe - lost in the quarters to Svetlana Kuznetsova.
