Francisco Cerúndolo’s run at the Shanghai Masters ended Sunday with a 6-3, 3-6, 6-2 loss to Czech player Jakub Menšík, bringing another early finish at a major tournament in what has otherwise been one of the Argentine’s most successful seasons. The defeat was especially frustrating for Cerúndolo, who had beaten Menšík in straight sets at the China Open in Beijing just eight days earlier. Entering Sunday’s match, the Argentine had won all three of their previous meetings.
This time, Menšík found a way through. The 21-year-old Czech controlled the opening set, breaking Cerúndolo in the fourth game and using his powerful groundstrokes to keep the Argentine on the defensive. Cerúndolo responded in the second set, saving a crucial break point before finally breaking Menšík’s serve late to force a decider.
But the momentum did not last. Menšík broke early in the third set, raced to a 3-0 lead and closed out the match in approximately two hours. The victory sends Menšík into the fourth round against France’s Arthur Gea, who produced one of Sunday’s biggest surprises by defeating third seed Ben Shelton in straight sets.
For Cerúndolo, the loss ends his Asian hard-court swing with a quarterfinal appearance in Beijing and a third-round exit in Shanghai. He remains Argentina’s highest-ranked men’s singles player, sitting at No. 20 in the ATP rankings entering the tournament. Yet judging his season by those two results would overlook how much the 28-year-old has accomplished in 2026.
Cerúndolo began the year by winning the Argentina Open in February, finally claiming his hometown title after falling short in the 2021 and 2025 finals. He defeated Luciano Darderi 6-4, 6-2 in the championship match, winning his fourth career ATP title in front of a home crowd in Buenos Aires.
Four months later came an even bigger breakthrough. At London’s Queen’s Club, Cerúndolo defeated American Tommy Paul 6-7(4), 6-4, 6-3 in a three-hour final to become the first Argentine to win the prestigious grass-court tournament. It was his first ATP 500 title and fifth career singles championship, strengthening his reputation as a player capable of winning well beyond the clay courts where he initially established himself.
His success on different surfaces has been a recurring theme throughout his career. Cerúndolo first attracted international attention by reaching the Miami Open semifinals in 2022, and his 2026 performances have further demonstrated that his best tennis can trouble leading opponents on hard courts.
In March, he reached the Miami Open quarterfinals after defeating former world No. 1 Daniil Medvedev. His run ended against Alexander Zverev, who won their quarterfinal 6-1, 6-2. The pattern continued during the Grand Slam season, where Cerúndolo produced promising results but could not quite turn them into a breakthrough appearance in the final eight.
He reached the fourth round of the Australian Open in January and the third round at Roland Garros in May. His Queen’s Club title raised expectations ahead of Wimbledon, but that momentum disappeared quickly when he lost his opening match to Spain’s Jaume Munar. At the US Open in September, Cerúndolo delivered one of his most impressive victories of the year, recovering from two sets down to defeat American Taylor Fritz in the third round.
His New York campaign ended one match later against Belgium’s Alexander Blockx, who won their fourth-round encounter 6-3, 4-6, 7-5, 7-5. Taken together, those performances show both the progress Cerúndolo has made and the challenge still facing him. He has established himself as one of Latin America’s leading players, won titles on clay and grass in the same season, and demonstrated that he can compete with highly ranked opponents on hard courts.
What remains missing is a Grand Slam quarterfinal appearance or another deep run at the Masters 1000 level. Sunday’s defeat in Shanghai does not erase his accomplishments. Menšík, ranked No. 15, is one of the ATP Tour’s strongest young competitors, and Cerúndolo had beaten him only a week earlier.
But with the season approaching its final stretch, the Argentine faces a familiar challenge: turning the high points of an already successful year into more consistent results against the game’s strongest opponents. After five ATP titles and repeated appearances in the world’s top 20, the next step is no longer proving he belongs among the best. It is finding a way to stay in contention deeper into tennis’s biggest tournaments.
