MELBOURNE: Top-seeded Aryna Sabalenka overcame several bouts of inconsistent play Friday to beat Anastasia Potapova 7-6 (4), 7-6 (7) and advance to the fourth round at the Australian Open. Sabalenka, chasing her third Australian Open title in four years, led 6-5 and 40-0 in the opening set but Potapova saved all three set points to send it to a tiebreaker. Sabalenka led 3-0 in the tiebreaker before Potapova leveled at 3-3. Sabalenka held two more set points and clinched the set when she laced a backhand down the line off Potapova’s second serve.
