MELBOURNE, Australia — Serena Williams became a time traveler on Sunday, pulled back to the past to essentially face down her much younger self.
Across the net from her in the fourth round of the Australian Open stood the 22-year-old Belarusian Aryna Sabalenka, who turned pro at 14, like Williams, and whose strategy called to mind Williams’s game plan at the same age: If at first you don’t succeed, hit harder.
Williams, 39, stared down Sabalenka, and after two gripping hours, Sabalenka blinked. In the 10th game of the deciding set, Sabalenka mustered one point on her serve as Williams, a seven-time champion, seized the break and a 6-4, 2-6, 6-4 victory to set up a quarterfinal meeting with Simona Halep, who dispatched the 19-year-old Iga Swiatek in three sets.
