Ann Li vs. Zeynep Sonmez — Osaka 2026 Round-of-16 Match Report
Zeynep Sonmez had already proved this year that she could beat Ann Li.
At Wimbledon, the Turkish No. 1 fought past the American 7-5, 1-6, 6-4 in the opening round. Four months later in Osaka, the rematch barely resembled it.
Li was simply too strong.
The top seed never dropped serve, saved all six break points she faced and dismantled Sonmez 6-3, 6-1 to move into the Japan Open quarterfinals.
Sonmez had arrived on the back of an excellent comeback against Maya Joint, winning 3-6, 6-4, 6-3 after producing 34 winners and only four unforced errors.
Against Li, there was no similar escape route.
Sonmez Stays Close Until Li Finds the First Break
The opening five games gave little indication of what was coming.
Li held for 1-0, Sonmez answered, and both continued protecting serve through 3-2.
Then the balance shifted.
Li attacked the Sonmez serve and broke for 4-2.
That single break was enough.
Li consolidated for 5-2, Sonmez held once more for 5-3, and the American served out the set 6-3.
Sonmez had created chances on return, but Li kept shutting the door.
That became the theme of the match.
Li Turns the Second Set Into a Rout
The second set started badly for Sonmez and never really recovered.
Li broke immediately for 1-0 and held for 2-0.
Sonmez stopped the early run with a hold for 2-1, but Li moved through another service game before breaking again for 4-1.
From there, the distance only grew.
Li held for 5-1 and then broke Sonmez one final time to finish the match 6-1.
Three breaks in the set.
No service games lost all afternoon.
Six Break Points, Zero Breaks
That is the statistic Sonmez will probably dislike most.
She created six break points against Li.
She converted none.
Li finished the match having won all eight of her service games, while Sonmez held only four of eight.
The American also dominated behind both deliveries, winning 76 percent of her first-serve points and 63 percent behind the second serve.
Seven aces helped.
Sonmez, by contrast, landed an excellent 78 percent of her first serves, yet won only 52 percent of those points. Li kept getting into the rallies and kept making the first serve feel much less valuable than the percentage suggested.
The overall numbers were just as clear.
Li won 77 of 133 points, produced 22 winners and finished with a 1.66 dominance ratio.
Sonmez managed 13 winners against 32 unforced errors.
This was not one of those matches decided by two loose games.
Li controlled it.

From Emerson Jones to Sonmez, Now Lilli Tagger Awaits
Li’s Osaka campaign has already required two very different wins.
In the opening round, qualifier Emerson Jones pushed her hard before Li recovered from a set down to win 5-7, 6-0, 6-3.
Against Sonmez, there was no such drama.
Next comes Austria’s Lilli Tagger, who has already removed fifth seed Liudmila Samsonova and then beat Tereza Valentova to reach the quarterfinals.
Li therefore remains in a Japan Open section that has produced more surprises than the seedings suggested.
But after this performance, the top seed also looks increasingly like the player everyone else will have to move.
Sonmez had the better of their Wimbledon meeting.
In Osaka, the American answered emphatically.
