Two-time Grand Slam champion Naomi Osaka is through to the quarter-final in Toronto, beating the young Pole Iga Swiatek 7-6, 6-4 in an hour and 51 minutes. Iga gave her best to stay in touch with the better-ranked opponents, saving four out of seven break points and wasting two set points at 5-4 and 6-5 in the opener before losing the ground in the closing stages of the second set to propel Naomi through.
Osaka was 4-2 down in the first set, pulling the break back immediately and fending off those two set points on own serve to set up a tie break that she claimed 7-4 with three mini-breaks. They traded breaks in games four and five in set number two, staying neck and neck until the tenth game when Naomi broke at love to seal the deal and set the quarter-final clash with Serena Williams.
World no. 91 Marie Bozukova qualified for the main draw and she has a great run so far, toppling Jelena Ostapenko 6-2, 6-2 in an hour and 19 minutes for the first WTA quarter-final. The Czech saved all four break points and took full advantage of ten double faults and 48% of the first serve in from Ostapenko, racing into a 4-0 lead in the first set and crossing the finish line with two more breaks in set number two to advance into the last eight.
Wimbledon champion Simona Halep defeated Svetlana Kuznetsova 6-2, 6-1 in 67 minutes, playing against each other for the first time since the Canadian Open three years ago. The Romanian had some dominant wins over the Russian on clay half a decade ago and had the upper hand in this one as well, saving both break points and stealing Stetlana's serve four times from ten opportunities to sail into the quarter-final.
Halep broke in the second game of the match after a loose forehand from Kuznetsova who suffered another break at 2-5 to hand the opener to world no. 4. Simona saved two break chances at the beginning of the second set and moved in front in the next game after a forehand mistake from the veteran.
A return winner pushed Halep 4-0 in front and the victory was in her hands after hold in game seven, setting the quarter-final meeting with Bouzkova on Friday night.
