Nikola Bartunkova vs Amanda Anisimova — R32 — Canadian Open

Four breaks in a single set is where this turned. Bartunkova had won 67 percent of her first-serve points in the opener while converting all three break chances she saw, then managed 30 percent in the second as Anisimova won 100 percent of hers. The reset didn't hold. Five service games changed hands in the third before the No. 8 seed broke in game 9 for 5-4 and served it out, 2 hours and 45 minutes after opening with four double faults — reasonable from a player who hadn't completed a match since her Wimbledon loss to Madison Keys, with a bye and a walkover carrying her into the round of 32 at the Canadian Open. Elina Svitolina, the No. 10, is next.
