MELBOURNE, Australia - CoCo Vandeweghe sent top seed and reigning champion Angelique Kerber crashing out of the Australian Open in straight sets on Sunday night.
Appearing in the last 16 at Melbourne Park for the first time, Vandeweghe rose to the occasion in magnificent fashion, reeling off the final five games to close out a 6-2, 6-3 victory.
"I believe this is my first No.1 win, so I'll take that," said Vandeweghe. "I was feeling bad out there but you've just got to keep at it and keep going. I had to trust my game to beat her and I did."
Vandeweghe made a mockery of her weary limbs, a spectacular display of attacking tennis producing six aces and 24 other winners in little over an hour.
After an even start, Vandeweghe fired a backhand crosscourt to claim the first break, before repeating the trick to wrap up the set. This stung the World No.1 into life, breaking Vandeweghe to open the second set. There was to be no comeback, though.
Capitalizing on a series of uncharacteristic Kerber errors, the American leant on her forehand to draw level at 3-3, before a big backhand gave her the opportunity to serve for the match. By this point Kerber was rapidly running out of ideas, sending a return beyond the baseline to surrender her crown.
