CINCINNATI/WASHINGTON, August 23, 2026 (by Michael Dickens)
At times during his Cincinnati Open semifinal, Frenchman Arthur Fils floated about the tennis court like a butterfly. Other times, he stung like a bee. Like the late, great boxer Muhammad Ali, once Fils got his momentum going, there was no stopping his one-two punch. He let his tennis racquet do his talking – and it had plenty to say.
On Saturday afternoon, neither lightning strikes nor a touch of rain could stop Fils. Ditto for Flavio Cobolli, who was the highest-remaining seeded player at No. 7 as semifinal play took place in the ATP Masters 1000 hard-court event under threatening skies.
In just 67 minutes, the French No. 1 and 21st seed Fils went from a break down to a straight-set winner over the Italian No. 2 Cobolli, winning 6-3, 6-4, to reach the biggest ATP Tour final of his career – his first ATP Masters 1000 title match – and third final of the season following Doha and Barcelona.

By winning, the 22-year-old Fils became just the second Frenchman to reach the Cincinnati final in the Open Era after Guy Forget in 1991 – and he’s the youngest Frenchman in 20 years to reach an ATP Masters 1000 final, too. His victory over Cobolli was his fourth win over a Top-10 player this season, and second one during this event after defeating No. 8 Alex de Minaur of Australia in the fourth round. He improved his win-loss record this season to 31-11.
“I was very happy with the performance,” Fils said during his post-match interview with ATP Media. “I started pretty slowly. I was a bit tight, but I think from 4-3 in the first set when I won those long rallies, just the momentum came my way and I felt so much better. Especially on the serve, because in the first couple of games I didn’t serve good at all, and then after it was very good. So, I’m very happy with the performance.”
After Cobolli and Fils completed their warm up, rain began to fall and lightning strikes could be seen in the area near the Lindner Family Tennis Center. The players left the P & G Stadium Court and were given another opportunity to warm up when they returned. First point was played about 48 minutes after the scheduled 1:30 p.m., start time. Although he admitted during his post-match interview that “it’s not easy” dealing with the disruption, the delay didn’t seem to affect Fils.
Although he found himself down a break 2-1 after just three games of the semifinal. Immediately, Fils got the break back and went to work from there. He did not ease up until he had secured victory over Cobolli.

“I came out on the court, and it is a semifinal, so of course you are a bit more nervous. But, then, the rain arrived and you’ve got to wait,” Fils said. “Then, after you come back the conditions are completely different and everything altogether was a bit tough to deal with. But I’m pretty happy with the way I managed.”
The World No. 21 Fils has risen to World No. 11 by reaching the Cincinnati final – a career-best ranking. He did it by winning 82 percent (27 of 33) of his first-serve points, converted three of four break points and hit 22 winners. Fils outpointed Cobolli 56-45.
Cobolli, who was held in check by Fils, generated just three winners and committed 22 unforced errors. Despite the loss, Cobolli will rise to a new career-best ranking of World No. 6 on Monday.
Meanwhile, everything seems to be coming together at the right time for Fils, especially with the start of the US Open just a week away. Now that he’s healthy and playing free of pain in his lower back, it seems the sky’s the limit for him. He’s 8-2 in his past 10 hard-court matches, with both loses coming against World No. 11 Rafael Jodar of Spain, in the opening round at Washington, D.C., and in the quarterfinals at Montreal last week.

On Sunday afternoon, Fils will be opposed by No. 17 seed Frances Tiafoe of the United States, who won an all-American semifinal battle over No. 27 seed Brandon Nakashima, 7-5, 6-3, in one hour and 42 minutes to advance to his 13th career ATP Tour final – his third one of 2026 after Acapulco and Halle – and second at ATP Masters 1000 level after reaching the Cincinnati Open final two years ago.
The World No. 23 Tiafoe’s PIF ATP Live Ranking has risen to No. 11 on the strength of his run to the Cincinnati final and he’s the third American man to reach multiple Cincinnati Open finals this century following Andy Roddick and Mardy Fish. Nakashima, 25, who was a finalist at Montreal, heads to the US Open with a 12-3 record on the North American hard-court swing and a career-best PIF ATP Live Ranking of No. 16.

After exchanging four breaks of serve in the first six games of the semifinal, the native of Hyattsville, Md., erased three set points during a lengthy, 11-minute-plus 16-point 10th game. He wrapped up the 63-minute opening set with his fifth ace out wide that painted the doubles alley tape perfectly.

Then, the 28-year-old Tiafoe broke Nakashima twice in the second set – including in the final game of the match – to close out his seventh career win over the San Diego, Calif., native. He collected his 37th victory of the season, the most of an American man, for his effort.
Tiafoe, who only placed 52 percent (39 of 75) of his first serves in play, managed just seven aces and committed five double faults. His serve did improve during the second half of the match and he wound up winning 30 of 39 first-serve points (77 percent). Tiafoe hit 30 winners to 28 unforced errors and converted five of 10 break points while saving seven of nine break points he faced from Nakashima. Tiafoe outpointed his opponent, 77-66.

Looking ahead to Sunday, Tiafoe has met Fils once already this season. The Frenchman beat Tiafoe in the round of 32 at the Miami Open last March.
When Tiafoe was asked during his on-court interview with ATP Media how it felt to make it to the Cincinnati Open final, he smiled and replied: “It feels pretty damn good. I’m really happy with it. It’s been a great week and a great weekend, unexpectedly, so I’m super happy.”

Around the Cincinnati Open
While the men’s singles semifinals dominated play on P & G Stadium Court, next door on the Grandstand Court the men’s doubles semifinals took place.
First, No. 2 seeds Marcel Granollers of Spain and Horacio Zeballos of Argentina, the 2021 Cincinnati Open champions and the only seeded-team left, were upset by alternates Constantin Frantzen of Germany and Robin Haase of the Netherlands, 6-3, 3-6, 10-5, in one hour and 17 minutes. The German/Dutch duo combined to hit five aces, won 71 percent of their total service points, and outpointed their opponents 55-53.
The victory was their 30th of the season – they’re 30-20 in all competitions – and Franzen and Haase are 17-7 in match tie-breaks. They’ve won one title this year, a Challenger 175 at Valencia on clay in May.
In the second semifinal, Montreal champions Orlando Luz and Rafael Matos of Brazil reached their second-straight ATP Masters 1000 final after defeating Hugo Nys of Monaco and Edouard Roger-Vasselin of France, 6-4, 2-6, 10-2, in one hour and 25 minutes.
The match was suspended by rain and lightning after Luz and Matos had won the opening set 6-4 and were on serve at 1-2 in the second set.

Saturday’s Cincinnati Open results
Sunday’s Cincinnati Open order of play
By the numbers
This year’s tournament semifinal lineup guaranteed there would be a new ATP Masters 1000 champion. All four semifinalists – Flavio Cobolli, Arthur Fils, Brandon Nakashima and Frances Tiafoe – have never won an ATP Masters 1000 crown. The last time there was a semifinal lineup without an ATP Masters 1000 champion was in 2023 at Toronto (Alejandro Davidovich Fokina, Alex de Minaur, Tommy Paul, Jannik Sinner).
“Quotable …”
“[It will be] a hell of a show. And hopefully another ‘W’ with that. He’s a hell of a player. Moves great, serves great. He has the shot making [ability]. He’s going to want it, he’s going to be pumped up, and so am I. May the best man win.”
– Frances Tiafoe of the United States, during his on-court interview after defeating fellow American Brandon Nakashima to advance to Sunday’s Cincinnati Open men’s final against Arthur Fils.
