TORONTO — Aryna Sabalenka’s world number one ranking will be on the line at the WTA 1000 tournament in Toronto, where the Belarusian star aims to extend her hard court dominance in the build up to her US Open title defense.

Sabalenka has won 23 of her 24 hard court matches this year, the lone defeat her loss to Elena Rybakina in the Australian Open final.

But she was turfed out in the quarter-finals on the clay of Roland Garros and fell to Naomi Osaka in the round of 16 on the grass courts of Wimbledon.

If Sabalenka fails to reach the round of 16 in Toronto, Kazakhstan’s Rybakina can rise to number one if she lifts the trophy.Sabalenka has never made it past the semi-finals in Canada, which alternates each year between Montreal and Toronto, but she said she was feeling rested and ready to reassert herself after taking time off in the wake of her All England Club exit.

“Clay and grass, I wouldn’t say they were that bad,” she said. “I was trying a couple of things, didn’t go the way that I expected. And now we’re kind of back to basics and I really hope it’s going to work out well.”

Sabalenka had exited Wimbledon saying she wanted to “forget about tennis”. She did that with a summer holiday on the Greek island of Mykonos.

“I think the rest was much-needed,” she told reporters on Sunday. “I spent there five, six days maybe. I felt much better, I couldn’t wait to get back on court and start working towards my goals for this swing.”

Sabalenka heads a top half of the draw that also includes two-time winner Jessica Pegula, the third seed, 2024 finalist Amanda Anisimova and seventh-seeded Iga Swiatek of Poland.
