TORONTO — Serena Williams advanced to the Rogers Cup semifinals, beating soon-to-be-top-ranked Naomi Osaka of Japan 6-3, 6-4 Friday night in a rematch of their U.S. Open final.
Williams faced Osaka for the first time since losing to her in a contentious 2018 U.S. Open final. The 37-year-old Williams played her first event since losing the Wimbledon final.
“I knew her game a little bit more, so that’s a little easier. I’m just overall a little bit better,” Williams said. “I know her game. I watch her a lot. I know what I need to do to hopefully try to get a win today, and it helped a little bit. I go into every match thinking I can do it, but sometimes that doesn’t happen.
Williams will face Czech qualifier Marie Bouzkova on Saturday. Bouzkova led fourth-seeded Simona Halep of Romania 6-4 when the Wimbledon champion retired because of a left Achilles problem.
Williams, ranked 10th and seeded eighth, won the Rogers Cup in 2001, 2011 and 2013 — all in Toronto — and has a tournament-record 33 victories in 37 matches. She won the last of her 72 singles titles at the 2017 Australian Open.
Osaka will improve from No. 2 to No. 1 on Monday when the rankings are announced.
“I’m not really mad at this,” Osaka said. “I don’t think it was up and down. I think I played pretty well. And she just played amazing, which that’s what she does. … I just feel like the entire match I was a bit too defensive. I know that can’t be helped when I’m playing against her.”
In the afternoon, Bianca Andreescu became the first Canadian Rogers Cup semifinalist since 1979, overcoming a groin injury to beat third-seeded Karolina Pliskova of Czech Republic 6-0, 2-6, 6-4. Andreescu will face American Sofia Kenin, a 7-6 (2), 6-4 winner over sixth-seeded Elina Svitolina of Ukraine.
The 19-year-old Andreescu, from nearby Mississauga, is returning from a right shoulder injury that sidelined her since the French Open in May. She won in Indian Wells in March for her first WTA Tour title.
“In the third set I told myself, ‘Go big or go home,'” Andreescu said. “Literally go home. My home is like two minutes from here. I just went out there and I never gave up because it’s not over until it’s over.”
Andreescu played her fourth consecutive three-set match. She needed a medical timeout in the second set for treatment of the groin injury.
“It’s not easy, that’s for sure,” Andreescu said. “Right now, I’m just really happy my mind and my body are holding up. My team, too, I’m so sorry guys for putting you through all of that.”
The 20-year-old Kenin upset top-ranked Ashleigh Barty in the first round.
