Playing the fourth round of the Australian Open for the first time, Coco Vandeweghe eliminated reigning champion and world number one Angelique Kerber in straight sets.
Without even facing a break point in the first set, the 35th-ranked Vandeweghe raced to 6-2, hitting 16 winners to Kerber's four and winning 8 out of 10 points at the net, while Kerber never approached the net. The German top seed attacked early in the second set to open it with a break, but the American won four straight games from 3-2 down for the biggest victory of her career.
Vandeweghe's opponent in the Australian Open quarterfinals will be seventh seed Garbine Muguruza, who beat Romanian Sorana Cirstea 6-2 6-3. The second quarterfinal pair will be Venus Williams vs. Anastasia Pavlyuchenkova, as the American seed No.13 ended the run of Mona Barthel 6-3 7-5 and the Russian seed No.24 beat her eighth-seeded compatriot Svetlana Kuznetsova 6-3 6-3.
Monday's schedule features four more round of 16 matches, so we'll get the quarterfinalists in the bottom half of the draw. (photos: Jimmie48)
