MELBOURNE: Top-ranked Aryna Sabalenka, attempting to win her third Australian Open title in four years, reached the quarterfinals on Sunday with a victory over No. 17 Victoria Mboko of Canada 6-1, 7-6 (1). Sabalenka, using a high-powered serve that produced three aces in the first set, rolled over the 19-year-old Canadian in just 31 minutes on Rod Laver Arena. Sabalenka was not quite as dominant in the second set — producing a few more unforced errors — against Mboko, who played well enough to beat many players but not the two-time Australian Open champion.
