The Associated Press Coco Gauff celebrates winning the second set against Belinda Bencic on Sunday.

LONDON — When power meets power, getting in the first blow can sometimes be the key.

In a matchup of two of the hardest hitters on tour, that was Naomi Osaka’s strategy against top-ranked Aryna Sabalenka in the most highly awaited matchup of Wimbledon so far this year.

Sabalenka had beaten Osaka in all three of their previous matches this year — including at the same stage of the French Open last month.

“On the clay courts I felt like she was pushing me back a lot. I just tried to do it to her first,” Osaka said.

The tactics worked, and Osaka outslugged Sabalenka 6-2, 7-6 (2) to reach the quarterfinals at the All England Club for the first time on Sunday.

Osaka’s pace and flat groundstrokes overwhelmed Sabalenka.

“Obviously we’re big ball strikers. It’s not like I’m going to start running around the court trying to draw an error from her. I can only focus on my strengths,” Osaka said.

“I just tried to serve really well, because it’s grass. I also tried to get the upper hand in the rallies first.”

Osaka’s power had an even bigger impact than usual as her balls flew through the air faster on the warmest day of the tournament so far: The temperature during the match reached 28 degrees Celsius (82 Fahrenheit).

“She overpowered me,” Sabalenka said. “I felt like it was incredible level from her.”

Besides Paris, Sabalenka also beat Osaka in Indian Wells, California, and Madrid this year.

“That really sucked,” Osaka said. “So I wanted to turn it (around).”

When it was over, Osaka performed a few fist pumps, let out a brief smile and then placed her racket over her head and spun around in delight to celebrate her first career win on Centre Court.

“It’s been a long time since I’ve had so much fun on the court,” Osaka said. “And to do it here, it really means a lot.”

Coco breaks through

Coco Gauff reached the Wimbledon quarterfinals for the first time by overcoming Belinda Bencic 4-6, 3-6, 6-4 just before the 11 p.m. curfew.

Gauff will next meet fellow American Jessica Pegula, who beat Iva Jovic — another American — 4-6, 6-3, 6-1.

Djokovic sets record

Earlier on Centre Court, Novak Djokovic beat 132nd-ranked qualifier Roman Safiullin 7-6 (6), 6-3, 3-6, 6-3 for a record 106th match victory at the All England Club.

Djokovic will next play third-seeded Felix Auger-Aliassime, who beat Alejandro Davidovich Fokina 6-7 (4), 7-6 (6), 6-3, 6-7 (2), 6-1.

Top-ranked Jannik Sinner beat Japanese qualifier Shintaro Mochizuki 6-3, 7-6 (0), 6-3 and will next meet Jan-Lennard Struff, who advanced when Hubert Hurkacz retired while trailing 4-2 in the fifth set due to a strained abdominal muscle.
