Pakistan, Aug. 7 -- Second seed Elena Rybakina, third seed Jessica Pegula and fourth-seeded Coco Gauff all advanced to the third round of the WTA 1000 tournament in Toronto on Wednesday. Australian Open champion Rybakina, of Kazakhstan, began her hardcourt run ahead of the US Open by outlasting Australian Daria Kasatkina 6-3, 5-7, 6-4 in 2hr 33min.

World number two Rybakina began the match by hitting six consecutive winners but also made 58 unforced errors. "I want to see better serve, the percentage," Rybakina said after coughing up 16 double faults against 15 aces. "Today in key moments it worked, but still the percentage is quite low.
