Flavio Cobolli completed a remarkable week in Acapulco with a 7-6 (4), 6-4 victory over Frances Tiafoe to lift the ATP 500 trophy. The straight-sets scoreline belies a hard-fought encounter that lasted two hours and nine minutes, with the opening set alone running 70 minutes.

The win is Cobolli’s third ATP title and matches the biggest level of his previous triumphs. His first two tour-level trophies came last year, both on clay: Bucharest, an ATP 250, and Hamburg, an ATP 500. With the rankings update on Monday, he is projected to move from No. 20 to a new career-high of No. 15, surpassing his prior peak of No. 17.

Both finalists had dramatic semifinal nights. Cobolli rallied from 3-1 down in the deciding set to beat Miomir Kecmanovic, 7-6 (5), 3-6, 6-4. Tiafoe survived an all-American duel with Brandon Nakashima, 3-6, 7-6 (6), 6-4, after Nakashima served for the match at 6-5 in the second set and then came within two points of victory at 6-all in the tiebreak.

In the final Tiafoe threatened early, holding a 3-1 advantage in the first-set tiebreak before Cobolli edged the set. Tiafoe rallied again in the second, breaking back to level at 4-all, but Cobolli closed the match by winning eight of the final 10 points, breaking for 5-4 and sealing the title with an ace, his 10th of the match.

The result also carries historical notes. At 23, Cobolli is the youngest champion in Acapulco since a 22-year-old Dominic Thiem won in 2016. He is the first Italian to capture an ATP title this year and, as the nation’s No. 3, will join countrymen Jannik Sinner and Lorenzo Musetti, currently ranked No. 2 and No. 5, in the Top 15.

Frances Tiafoe advanced to the Acapulco final after recovering from a set down to beat fellow American Brandon Nakashima, 3-6, 7-6 (6), 6-4.

Nakashima served for the match at 6-5 in the second set and earlier had created pressure with triple break point at 3-all. He was also two points from victory at 6-all in the second-set tiebreak, but Tiafoe survived a 71-minute second set and carried the momentum into the decider. He broke in the first game of the third set, extended the lead with another break for 5-2, and, after Nakashima reclaimed one break to close to 5-4, served out the match on his second attempt with a big overhead.

“It’s incredible. The stars are definitely aligning, man, it’s not making sense, anything that happened,” Tiafoe said afterwards.

“Things started to make sense when I was down, obviously I had a couple of net cords there. You know, made every return there at 6-5, but obviously I wasn’t feeling my best. I was just competing and battling, and sometimes you get lucky. Played great tennis in the third—in the third I was the better player.

“Just battling, man. Never say die. I was ready to empty the tank.”

Tiafoe had already shown that temperament earlier in the week, coming back from the brink in his second-round match. He fought off double match point down 6-4 in the third-set tiebreak to defeat Aleksandar Kovacevic, 6-4, 3-6, 7-6 (7), and again displayed resilience in Friday’s semifinal.

The victory moves Tiafoe into the 11th ATP final of his career and gives him a chance at the biggest title of his career. His three ATP titles to date all came at the ATP 250 level, in Delray Beach in 2018 and in Houston and Stuttgart in 2023. He has finished runner-up in three finals at the ATP 500 level or higher: Vienna in 2021 (ATP 500), Tokyo in 2022 (ATP 500) and Cincinnati in 2024 (Masters 1000).

Waiting in the Acapulco final is Italy’s Flavio Cobolli, who rallied from 3-1 down in the third set to beat Miomir Kecmanovic earlier, 7-6 (5), 3-6, 6-4. Cobolli will pursue his third ATP title and the equal-biggest of his career, having won an ATP 500 in Hamburg last year.

Frances Tiafoe will contest the Acapulco title after coming from a set down to defeat countryman Brandon Nakashima in a dramatic semifinal, 3-6, 7-6 (6), 6-4.

Nakashima served for the match at 6-5 in the second set and had earlier brought up triple break point at 3-all, plus two match points at 6-all in the second-set tiebreak. Tiafoe persevered in a marathon 71-minute second set, then broke in the opening game of the decider and again for a 5-2 lead. Nakashima recovered one break to close to 5-4, but Tiafoe served out the win on his second try, finishing with a big overhead.

“It’s incredible. The stars are definitely aligning, man, it’s not making sense, anything that happened,” Tiafoe said afterwards.

“Things started to make sense when I was down, obviously I had a couple of net cords there. You know, made every return there at 6-5, but obviously I wasn’t feeling my best. I was just competing and battling, and sometimes you get lucky. Played great tennis in the third—in the third I was the better player.

“Just battling, man. Never say die. I was ready to empty the tank.”

The win puts Tiafoe into the 11th ATP final of his career and offers a chance at the biggest title of his career. His three ATP titles to date all came at the ATP 250 level: Delray Beach in 2018 and Houston and Stuttgart in 2023. He has reached finals at the ATP 500 level or higher three times previously but finished runner-up each time: Vienna in 2021 (ATP 500), Tokyo in 2022 (ATP 500) and Cincinnati in 2024 (Masters 1000).

Awaiting Tiafoe in the Acapulco final will be Italy’s Flavio Cobolli, who rallied from 3-1 down in the third set to beat Miomir Kecmanovic earlier on the day, 7-6 (5), 3-6, 6-4. Cobolli will pursue his third ATP title and the equal-biggest of his career, having won an ATP 500 in Hamburg last year.
