Coco goes loco again! Vandeweghe destroys another racquet

American tennis player Coco Vandeweghe is one angry women, demolishing her second racquet of the summer at the Sydney International.

Vandeweghe was on her way to a big loss against Duan Yingying when she completely snapped early in the second set.
