Gauff rolls past Wang in Toronto, Keys withdraws

TORONTO -- Top-seeded Coco Gauff cruised past Yafan Wang 6-4, 6-2 on Thursday in the second round of the National Bank Open.

Preparing for her U.S. Open title defense, Gauff played her first hard-court match since the Miami Open in April.

"It's not easy transitioning from all these different surfaces in such a short amount of time," said the 20-year-old American, coming off a third-round loss on clay in the Paris Olympics. "Happy to get pushed through."

Second-seeded Aryna Sabalenka, the Australian Open winner, faced Yue Yuan in the night session.

No. 5 Daria Kasatkina, No. 6 Liudmila Samsonova, No. 8 Emma Navarro and No. 10 Anna Kalinskaya advanced. No. 7 Madison Keys retired from her match against Peyton Stearns because of a thigh injury while down 3-0 in the third set.

Kasatkina beat Amanda Anisimova 6-4, 6-3; Samsonova topped Moyuka Uchijima 6-4, 6-2; Navarro beat Magda Linette 6-2, 6-4; and Kalinskaya edged Lesia Tsurenko 6-2, 6-2.

Canadian Leylah Fernandez, seeded 15th, dropped out with a 6-4, 6-2 loss to qualifier Ashlyn Krueger. Marina Stakusic, a 19-year-old wild card from nearby Mississauga, was thumped 6-0, 6-2 by Taylor Townsend.
