Francisco Cerúndolo is an Argentine professional tennis player who has won five ATP Tour singles titles and reached a career-high ranking of world No. 18. Born in Buenos Aires on 13 August 1998, he came through a tennis family and built his early reputation as a clay-court player before converting that game to grass and hard courts, a transition that reshaped how the tour reads him.
His career sits in an unusual place. He has a Masters 1000 semifinal, titles on three surfaces and a top-20 ranking, yet his Grand Slam record has not kept pace with any of it. Understanding Cerúndolo means understanding that gap.
Playing style
Cerúndolo is right-handed with a two-handed backhand and stands 1.85m. The forehand is the organising shot of his game — heavy, high-margin and hit with enough topspin to push opponents behind the baseline on slower surfaces. He builds points rather than shortening them, preferring to work an opponent out of position before committing to a finishing ball.
That construction is why the clay-courter label attached to him early and stuck longer than it should have. The forehand shape that dominates on clay travels less naturally to faster courts, where the ball sits up and the extra height stops being a weapon. His adaptation has been to flatten the forehand selectively and shorten the setup, taking returns earlier rather than defending from deep. The grass results are the clearest evidence that the adjustment took.
The Miami breakthrough
Cerúndolo’s arrival was abrupt. At the 2022 Miami Open, ranked No. 103 and playing his first Masters 1000 main draw, he reached the semifinals. The ATP records him as the lowest-ranked semifinalist in the tournament’s 37-year history and the first player to reach the last four on his Masters main-draw debut since Jerzy Janowicz at Paris in 2012.
The run mattered beyond the ranking points. It established that his clay-built game could hold up on a hard court against seeded opposition, a question that had followed every Argentine prospect of his generation.
Five ATP titles
Bastad, 2022. His maiden tour title came at the Swedish Open, where he beat defending champion Casper Ruud in the second round — the first top-10 win of his career — and defeated Sebastián Báez 7-6(4), 6-2 in the final.
Eastbourne, 2023. His second title arrived on grass, 6-4, 1-6, 6-4 over Tommy Paul. The ATP notes he became the first Argentine to win an ATP Tour title on grass since Javier Frana at Nottingham in 1995.
Umag, 2024. Back on clay, he beat Lorenzo Musetti 2-6, 6-4, 7-6(5) at the Croatia Open.
Buenos Aires, 2026. The Argentina Open title had eluded him twice, as runner-up in 2021 as a qualifier ranked No. 137 and again in 2025, when he lost the final to João Fonseca. He took it at the third attempt without dropping a set, beating Luciano Darderi 6-4, 6-2.
Queen’s Club, 2026. The biggest of them. Seeded seventh at the HSBC Championships, he recovered from a set down to beat Paul 6-7(4), 6-4, 6-3 in a final lasting three hours and two minutes, converting on a fifth match point. It was his first title above ATP 250 level and, per the ATP, made him the first Argentine champion at Queen’s Club.
“First ATP 500 title and second [trophy] of the year,” Cerúndolo said afterwards.
The grass conversion
Two of Cerúndolo’s five titles have come on grass, the surface his game was least expected to suit. That is the single most useful fact about him, because it contradicts the category he is usually filed under.
The mechanism is not mysterious. Grass rewards the returner who takes the ball early and the server who wins cheap points, and Cerúndolo’s forehand — when he flattens it — is a first-strike shot rather than a grinding one. On clay he has the patience to win long exchanges; on grass he has the ball-striking to avoid needing them. The surfaces that trouble him most are the medium-slow hard courts where neither advantage fully applies.
The Grand Slam question
Here is the anomaly. Cerúndolo has a Masters 1000 semifinal, an ATP 500 title, five tour titles across three surfaces and a career-high of world No. 18, achieved in May 2025 after reaching the Madrid semifinals with a win over then-No. 2 Alexander Zverev. His best Grand Slam result is the fourth round.
He has reached that stage at the Australian Open and at Roland Garros, and has not gone past the second round at Wimbledon or the US Open. For a player with his ranking and his surface range, that is a genuine outlier rather than a matter of bad draws.
The plausible explanation is structural. Best-of-five tennis punishes players who build points at length, because the physical cost of winning a rally compounds across four hours in a way it does not across two. A game predicated on constructing rather than shortening exchanges is expensive over five sets, and expensive games tend to run out in the second week rather than the first. The counter-argument is equally available: clay specialists have historically thrived in best-of-five for exactly the same endurance reasons. Cerúndolo’s Grand Slam record remains the open question of his career.
A tennis family
His younger brother, Juan Manuel Cerúndolo, born in November 2001, is also on the ATP Tour. A left-hander, he won the 2021 Córdoba Open as a qualifier on his ATP main-draw debut and reached a career-high of No. 54 in May 2026. Their father, Alejandro, has coached within the family setup.
The brothers produced one of the more memorable family days in recent Grand Slam history at Roland Garros in 2026. On the same afternoon Francisco was completing a four-set win over Hugo Gaston, Juan Manuel recovered from two sets and 1-5 down to beat world No. 1 Jannik Sinner on Court Philippe-Chatrier. The ATP recorded it as only the third time in the Open Era that two brothers had reached the third round at Roland Garros, after the Mayers in 1979 and the Zverevs in 2018.
