Thai qualifier Luksika Kumkhum has sent Swiss star Belinda Bencic crashing out in the second round of the Australian Open.
Two days after her shock opening-round triumph over seven-time major winner Venus Williams, Bencic bowed out 6-1 6-3.
Kumkhum will play either Croatian Petra Martic or Romania’s Irina-Camelia Begu in the round of 32.
