MELBOURNE: World number ones Andy Murray and Angelique Kerber both crashed out of the Australian Open on a day of major upsets Sunday, as Roger Federer fought his way closer to an 18th Grand Slam title.
Murray was stunned by 50th-ranked serve-and-volley specialist Mischa Zverev in four sets before Kerber, the women’s title-holder, tamely succumbed 6-2, 6-3 to Coco Vandeweghe. The unpredictable results, following six-time champion Novak Djokovic’s stunning loss in the second round, opened the door to a host of challengers — with Federer leading the charge.
