Naomi Osaka delivered one of the most significant upsets of her career on Sunday, defeating top-ranked Aryna Sabalenka 6-2, 7-6 at Wimbledon to reach the quarterfinals of a grass-court major for the first time, ending a match that snapped multiple historic streaks and rewrote the narrative of an increasingly remarkable season for the four-time major champion.
The victory was Osaka’s first over a top-10 player at any event played on a surface other than hard courts, entering the match at 0-13 in such matchups. It was also her first win over a world number one since 2019, before the extended breaks from professional tennis that shaped the middle portion of her career. The match lasted under ninety minutes on a day when temperatures reached 82 degrees Fahrenheit, the warmest of the tournament so far.
How the match unfolded
The heat played a role in amplifying Osaka’s most effective weapons. Her flat, hard-struck groundstrokes moved faster through the warm air than they would have in cooler conditions, giving Sabalenka even less time to set up and respond than the ball speed alone would have demanded. Osaka set the tone in the first set with early aggression and did not let Sabalenka settle into the kind of exchange that has historically favored the world number one.
In the second-set tiebreaker, a series of unforced errors from Sabalenka combined with Osaka’s relentless level put the match away decisively, 7-2. Osaka had faced only two break points across the entire match and saved both, while landing 87 percent of her first serves compared to 69 percent for Sabalenka. She led in aces and in total winners.
The historic streaks that ended
Sabalenka had not lost a set-by-set straight-sets defeat at a major since the 2020 US Open, a run of 121 consecutive matches without such a loss that represented the second-longest such streak in women’s major history. That streak ended Sunday.
She had also reached the quarterfinals or better at 14 consecutive major tournaments, the second-longest such run by any woman since the start of the century. That streak also ended on Sunday at Wimbledon, her first exit before the quarterfinals since 2022.
Perhaps most remarkably, Sabalenka had won 21 consecutive tiebreaks at major tournaments, the longest streak by either a man or a woman in the open era, surpassing a previous record held by Novak Djokovic. Osaka ended that streak as well, winning the second-set tiebreaker 7-2.
What the win means for Osaka
For Osaka, Sunday represented the convergence of a season full of personal milestones. She reached the second week of a non-hard-court major for the first time earlier at the French Open. She reached her first grass-court final at a warm-up event last week before retiring with a foot injury. And now she has reached her first Wimbledon quarterfinal, defeating a player who had beaten her three times earlier in 2026, including at a nearly identical stage at Roland Garros.
Sabalenka had beaten Osaka in Indian Wells, Madrid, and at the French Open all within the same calendar year before Sunday’s result. The fourth meeting produced a completely different outcome, with Sabalenka acknowledging after the match that Osaka had played at an exceptional level and that her own performance had not matched what she needed it to be.
Osaka will next face Karolina Muchova, who eliminated the defending Wimbledon champion in the previous round.
