NEW YORK (AP) — Aryna Sabalenka is going to be the No. 1 player in the WTA rankings next week, replacing Iga Swiatek there. That much is certain. The way Sabalenka is playing at the moment, she might very well supplant Swiatek as the U.S. Open champion, too. In Sabalenka’s first match since being assured of rising to the top of women’s tennis, she showed off the power-based game that allows her to dominate so many opponents, overwhelming No. 13 seed Daria Kasatkina 6-1, 6-3 on Monday night in Arthur Ashe Stadium to advance to her fifth consecutive major quarterfinal.
