The Belarusian arrived on Centre Court facing one of the trickiest tests in the women's draw. Ostapenko had beaten her in last year's Stuttgart final and owns two grass-court titles, while Sabalenka is still searching for her first on the surface.

Yet the world No. 1 never looked rattled.

In a contest defined by big serving and heavy hitting, the rallies were brief and the pace relentless. Sabalenka broke in the fifth game of the opening set and never relinquished control, sealing it with a 111mph ace.

Midway through the second set, Sabalenka briefly tried serve-and-volley but misjudged Ostapenko's looping return and shanked an overhead into court, laughing at her mistake before refocusing.

The moment reflected her evolution from pure ball-striker to more complete player, with improved net play, defence and variation now part of her game.

Ostapenko, the 2017 French Open champion, threatened briefly after trailing 6-4, 5-1, saving a match point and forcing Sabalenka to serve it out at 5-4. But under pressure for the first time, the top seed responded strongly before clinching victory as Ostapenko's return drifted long.

"She's really dangerous and the last match I played against her, I couldn't do anything. She just smashed me off the court," Sabalenka said.

"I'm really happy to get this win, especially in straight sets, and happy with the level."

Sabalenka had rated her first two matches at Wimbledon as an eight and nine out of 10, and this performance edged closer to perfection.

"The plan is to get better every day and do a little bit better than I usually do on this beautiful grass," she added.

The four-time Grand Slam champion is chasing a first Wimbledon final after three semi-final appearances at the All England Club. Her No. 1 ranking is also under threat if Elena Rybakina goes on to win the title.

Next up is Osaka, who reached the Wimbledon fourth round for the first time after a dominant run of seven straight wins without dropping a set. The Japanese star's form and flair make her one of the standout challengers heading into the second week.
