Britain’s tennis contingent delivered a mixed bag of results on the opening day of the US Open, with young qualifier Toby Samuel pulling off a stunning debut Grand Slam victory, Katie Boulter fighting her way through a three‑set battle, and seasoned campaigner Cameron Norrie suffering a third consecutive first‑round defeat. Samuel’s breakthrough came after he battled through three rounds of qualifying to earn a place in the main draw. In the first round he faced former world No. 20 Tomas Macháč, a seasoned Czech competitor who entered the match as a clear favourite.

Samuel, however, turned the tables in spectacular fashion, dispatching Macháč in straight sets 6‑2, 6‑3, 6‑2. The match lasted just 90 minutes, during which Samuel displayed a dominant serve and aggressive baseline play that left his opponent scrambling. By breaking early in both the first and second sets, Samuel built a comfortable lead and never looked back, only conceding a single service game in the third set before rattling off six consecutive games to seal the win. The victory propelled him into the ATP top 100 for the first time and set up a second‑round clash with the 18th‑seeded Jiri Lehečka, another Czech player, on Wednesday.

Reflecting on his performance, a visibly exhausted Samuel said, “I’m so tired – but otherwise I’m so happy to have got the job done there.” He added that the win was especially meaningful given his ranking of 683 a year ago. “I played a great match – I’m just so thankful to everyone that has supported me to this moment, and hopefully I can carry on into next week. The first two sets I wasn’t missing any balls.

In the third, he came out a bit stronger – I had a little dip in the first few games, but I came out of it quickly. I’m just going to try and do exactly what I did today in the next match.” In the women’s draw, British No. 1 Katie Boulder also advanced, but not without a fight. Boulter, 30, was paired against American wildcard Carol‑Young Suh Lee in a match that tested her composure.

After taking the first set 6‑4 and establishing a break advantage, Boulter’s momentum was interrupted by a string of double faults that allowed Lee to claw back into contention. The match stretched to a decisive third set, where Boulter, encouraged by her newly‑wed husband Alex de Minaur, found her rhythm on the noisy, partisan Court Five and delivered a dominant 6‑0 finish. The win sets up a potential second‑round encounter with Karolina Muchová, the Wimbledon runner‑up, promising a challenging test for the British champion.

Cameron Norrie, meanwhile, endured a disappointing exit, marking his third straight first‑round loss at a Grand Slam this season. The former British No. 1 fell to France’s Luca Van Assche in a four‑set battle, 7‑6 (8‑6), 2‑6, 2‑6, 3‑6. The opening set was a tightly contested affair that saw Norrie edge out a tiebreak, but his level dipped early in the second set, allowing Van Assche to seize control with confident baseline exchanges.

Norrie’s frustration grew as the match progressed; he managed to level the fourth set at 3‑3 with a series of impressive shots, yet Van Assche broke again to seal the match and advance to the second round for the first time in his career. Speaking after the loss, Norrie admitted his nerves had taken a toll. “It was really tough,” he said. “I was pretty nervous and it showed in the beginning of the first set, and I did well to steal that first set.

But I could never really maintain a good level of energy and momentum, and I’d play well for a little bit and then drop off a couple of games here and there. So that was super frustrating and pretty surprising. I felt like I lost to myself today.” Norrie’s recent form has seen him overtaken as Britain’s No. 1 by rising star Arthur Fery, who reached the Winston‑Salem final earlier in the week.

The shift in the British hierarchy underscores the emerging depth of talent on the UK circuit, highlighted by Samuel’s meteoric rise and Boulter’s continued resilience. For fans eager to follow the action, the US Open will be broadcast live on Sky Sports daily until September 13. Viewers can also stream matches without a contract via the NOW platform or the Sky Sports app, and those interested in attending live events can look forward to the Laver Cup at the O2 Arena in London from September 25‑27, also shown on Sky Sports.

Overall, the first day of the tournament delivered a blend of surprise breakthroughs, hard‑fought victories, and bitter defeats for the British contingent. Samuel’s ascent from the qualifying rounds to a top‑100 ranking spotlights the potential of the next generation, while Boulter’s gritty win reaffirms her status as a national champion capable of challenging top‑ranked opponents.

Norrie’s setback, though disappointing, serves as a reminder of the fine margins at the highest level of the sport. The upcoming rounds promise further drama as British players aim to build on their performances and chase deeper runs in one of tennis’s most prestigious events.
