The week leading up to the US Open 2025 is finally here, days filled with anticipation and excitement as the last Grand Slam of the tennis season is about to begin. The ATP tour is in full swing, with both Jannik Sinner and Carlos Alcaraz already setting foot in New York, joined by a group of top players ready to challenge them. Beyond the 32 seeded players, there is a group of extremely dangerous tennis players capable of causing upsets against the top-ranked players on the tour... and they are more than ready to do so.

From historic racket wielders who know how to triumph at Arthur Ashe to young talents eager to make a splash in the tournament, we have selected five different yet highly dangerous profiles that could be considered the dark horses of this US Open 2025. Five players to avoid in the early rounds... or five potential blockbuster matches from the start.

- Alexei Popyrin (#37 ATP): Although his performance in Canada was far from a disaster, reaching notable quarterfinals, the loss of points after being the 2024 champion has caused the Australian to drop in the rankings... placing him just outside the seeded group (not by much though). Consequently, Alexei becomes a real threat; his presence looms large in Grand Slams, having already shocked Novak Djokovic here with the biggest win of his career last year, showing prowess in serve, forehand, growing stability, and a lot of audacity and hunger: a revitalized power-hitter keen on proving his ranking does not reflect his true abilities.

- Learner Tien (#48 ATP): How did Learner Tien fare in his first Grand Slam of the year, the one on hard courts? A fourth-round finish in Australia after qualifying, including a significant win over Daniil Medvedev in one of the matches of the season. A promising start for his home tournament: coming from a winning streak against players like Rublev, Opelka, and Shapovalov, it seems like this petite left-hander's progression is on track. With the ability to be a wall, create impossible angles, and utilize his left-handed advantage, if there's a scorching hot and humid day when you can't feel the ball on your racquet... and you find Learner on the other side, you might just "learn" what a tough defeat in New York feels like.

- Marin Cilic (#61 ATP): It was here, in the concrete jungle, where Marin Cilic fulfilled his dreams. He showed the world that the expectations placed upon him weren't exaggerated, demonstrating that he possessed enough skill to shake up the giants of the tour. The memories of that dreamy September remain, but as they say, old rockers never die, as proven by his Wimbledon performance: at 36 years old with little match practice, he reached the second week with powerful serves and forehands. Despite not playing a single match since the London tournament, a player like him doesn’t require much prior feeling to display his best game... and facing a former champion in the first round is no easy feat for anyone.

Marin Cilic, the eternal day in New York.

- Hamad Medjedovic (#65 ATP): Only extreme heat and total humidity can prevent Medjedovic from making a significant impact in New York. After overcoming some physical issues that hindered him post a strong start of the season, his moment to shine may have just been delayed... until now: the court speed and lightness of the ball suit his kamikaze style of play well, and the US Open has always been a stage where big hitters, those who go all out and rely on power, have their breakthroughs in Grand Slams. It might be unlikely to see him reach quarterfinals or semis due to his stamina over two weeks, but rest assured that no top player wants to face Hamad in his Flushing Meadows debut.

- Jenson Brooksby (#91 ATP): Unconventional. Unique. Dangerous. Adjectives that perfectly describe this rare bird of the circuit, a player initially awkward but who utilizes that element of surprise in his game admirably. It was here that Jenson made his mark, reaching the fourth round in 2021 that foretold all the tennis talent within him: what better place than here to rediscover his best form after years of setbacks, pain, and emptiness. Although he doesn't come in with much match practice, his diverse game plans, ability to prolong rallies, and finesse in his racquet work are more than enough reasons to cause a surprise or two.
