MELBOURNE, Australia — If Rafael Nadal wanted a fitness test in the first week of the Australian Open, he got one in his almost four-hour, 6-3, 6-7 (4), 6-3, 6-3 victory over Diego Schwartzman on Sunday.
No. 3-ranked Grigor Dimitrov did it tough, too, before advancing to the quarterfinals at the expense of the last Aussie in the draw. Dimitrov avenged a loss two weeks ago to Nick Kyrgios with a 7-6 (3), 7-6 (4), 4-6, 7-6 (4) win on Sunday night.
He will next face Kyle Edmund, who reached his first Grand Slam quarterfinal with a 6-7 (4), 7-5, 6-2, 6-3 win over Andreas Seppi.
