Naomi Osaka defeats Daria Kasatkina 6-1, 6-3 to reach Wimbledon fourth round

Naomi Osaka defeated Daria Kasatkina 6-1, 6-3 on Friday at Wimbledon to reach the fourth round for the first time in her career. The match lasted 65 minutes. Osaka lost just five points on serve in the opening set and broke for a 4-3 lead in the second set after overcoming a three-deuce game.

Osaka is ranked No. 14. She had reached the third round at Wimbledon on three prior occasions but had never advanced further. Earlier in 2026 she reached the second week at Roland Garros for the first time.

After losing to world No. 1 Aryna Sabalenka at the French Open, Osaka returned to the United States for training. Her coach created drills to help her adapt to grass-court conditions. Osaka reached her first grass-court final last week at the Bad Homburg tournament before retiring from that match as a precaution with a foot injury.

"[I] understand grass-court tennis a lot more," Osaka told reporters Friday. " ESPN reported that Osaka has a 7-1 record on grass since the French Open loss and has dropped just one set during that stretch. Osaka will face Sabalenka in the round of 16 on Sunday.

ESPN reported that Sabalenka leads their head-to-head record 3-0 in 2026. The victory marks Osaka's first time reaching back-to-back fourth rounds at majors since the 2020 US Open and 2021 Australian Open; she has reached the semifinals of a major only once since winning her last title in 2021.
