Belinda Bencic dumps Venus Williams in Australian Open first round upset

The 20-year-old Swiss played the 37-year-old American great to perfection, soaking up the fifth seed's firepower and attacking her wavering serve with abandon.

In a tense grand slam opener that felt more like a final, Williams battled to keep touch in an enthralling second set, but Bencic unleashed two blazing forehand winners to close out the match in the 12th game.

The resurgent Bencic will meet the winner of Johanna Larsson and Luksika Kumkhum in the next round.
