British No 1 Jack Draper was upset in the Miami Open 2nd-round by 19-year-old Czech, Jakub Mensik, who fired 21 aces during his two tiebreak set win on Saturday. Alexander Zverev, Taylor Fritz, and Alex de Minaur advanced to the round of 32, but Andrey Rublev, Holger Rune, and Ben Shelton were all Day 4 casualties.
When the crowd is with any player, they are more hyped. I started the match today super relaxed, with no nerves. That was good, I served well. I had a quick break, he was maybe a little bit more nervous in the beginning, but I started well, and that’s what made the difference.

Draper, who has risen to a career-high of 7 in the world rankings, was beaten 7-6(2) 7-6(3) by his Czech opponent, despite making a fine start by breaking Mensik in the first game of the match. The teenage World No 54 leveled at 3-3 and produced top form from then on in.
“The most important thing today was the serve, that was key,” said Mensik. “I knew in the second set it was going to be tough at the 30/30 moments and in the tiebreak, so I just tried to stay focused. I’m super glad that I kept the focus until the end.”
With his 1 hour, 55 minute win over Draper, Mensik is just the 4th active male to own a positive 6-5 record against Top 10 players, including a win against No 6 Casper Ruud at this year’s Australian Open.
“It sounds really good,” Mensik said of his Top 10 record. “Hopefully I will keep rising as I am.”
“It is my first full year on the ATP Tour, so I am just enjoying every moment playing against these top guys. Jack has been playing incredibly the last weeks, months. I knew that it was an opportunity for me, so I took it.”
While Draper’s heavy topspin forehand was key to his success in Indian Wells, the Briton had trouble powering his way through Mensik, who responded with a barrage of explosive groundstrokes.
The 19-year-old also found comfort behind his serve, particularly in the second set, during which he won 86% of first-serve points.
The match on the Grandstand was disrupted by angry Brazilian supporters booing in the stands when it was announced that Joao Fonseca’s match against France’s Ugo Humbert, which was due on next, had been moved to the main Stadium court.
There was an immediate exodus as fans scrambled to leave their seats to make their way to the other court, where their favourite overcame Humbert 6-4 6-3.
Draper, who was leading 4-3, attempted to restart but asked the umpire to stop play because of the noise.
“I didn’t really know what was going on at first,” Draper told Sky Sports. “Obviously it was getting quite loud – I couldn’t hear the ball being hit. Those Brazilian fans had been in the stadium waiting for him to play all day and then, obviously, they changed the court. It’s not ideal, I can understand their frustration… we waited for a few minutes, and then it was fine.”
When play eventually resumed, the set stayed with serve to force another tiebreak, in which Mensik dominated, finishing with an ace to reach the 3rd round of an ATP Masters 1000 event for the 3rd time in his career.
In the 3rd round, Mensik will face Roman Safiullin from Russia, who rallied past Alexei Popyrin, the No 25 seed from Australia, 6-7(4) 6-3 7-5.

23-year-old Draper isn’t the only top performer from Indian Wells to crash out, with the other semi-finalists from that tournament – Carlos Alcaraz, Daniil Medvedev, and Holger Rune – all now beaten in Miami.
Rune met an inspired Reilly Opelka on Saturday, who came back to sink the 11th-seeded Dane and Indian Wells runner-up, 4-6 6-3 7-6(5).
The 6′ 11” American fired 21 aces en route to the win, reaching the 3rd round at an ATP Masters 1000 for the first time since 2022.
The former No 17, who reached the final in Brisbane in January, will next face 20th seed Tomas Machac from Czechia, who overcame Italy’s Matteo Arnaldi 6-2 1-6 6-3.
Meanwhile, British No 3 Jacob Fearnley also went out after a crushing straight-set defeat by top seed Alexander Zverev.
The German, who also beat the Scot in straight sets at the Australian Open, needed just 74 minutes to wrap up a 6-2 6-4 win against the 23-year-old.
Zverev looked comfortable against the British qualifier, mixing a solid serve with dominance from the baseline, while saving the only 2 break points he faced during the match.
For Zverev, who lost in the 1st round at Indian Wells, the win gave him a German record 145th Masters 1000 win, one more than Tommy Haas.
“Happy to kind of have improved a few things from Indian Wells where I didn’t feel well on the court. I didn’t feel like I played good,” Zverev told reporters. “Hopefully this is just the first of many matches for me here and I can continue playing well.”
Zverev will now face Australia’s Jordan Thompson, who powered past Frenchman Giovanni Mpetshi Perricard, 7-6(4) 7-6(1).
Despite the defeat, Fearnley will climb above Cameron Norrie to become British No 2 behind Draper when the ATP rankings are updated after Miami.
18-year-old Joao Fonseca upset 10th-seeded Ugo Humbert in straight sets in front of adoring Brazilian fans who had to relocate from the Grandstand to the Stadium at the last minute when the match was switched

On the Stadium court, a fearless Joao Fonseca surged into the 3rd round with a five-star display to defeat 19th seed Ugo Humbert from France, 6-4 6-3.
The 18-year-old Brazilian becomes the youngest player to reach round 3 at ATP Masters 1000 since Alcaraz in Paris in 2021, and his first at an ATP Masters 1000 in his fledgling career.
Due to the last-minute schedule change, the 2nd-round match was relocated from Grandstand to Stadium, and although the Brazilian fans arrived gradually, they quickly created a lively atmosphere as Fonseca surged to victory.
“When the crowd is with any player, they are more hyped,” said Fonseca. “I started the match today super relaxed, with no nerves. That was good, I served well. I had a quick break, he was maybe a little bit more nervous in the beginning, but I started well, and that’s what made the difference.
“Against lefties, they like the cross-courts with their forehand. My backhand today was pretty good, and I had the chance to play more aggressively with my forehand. I didn’t let him have opportunities on my serve either.”
Fonseca broke Humbert’s serve to love in the opening game and did not look back en route to a 71-minute win, in which he did not face a break point.
In a free-hitting performance, he dropped just 4 points on his serve throughout the encounter.
Fonseca has enjoyed a rapid rise at the start of the 2025 season, the reigning Next Gen ATP Finals presented by PIF champion claiming his maiden tour-level title in Buenos Aires in February.
He is now up to a new career-high 58 in the rankings.

3rd seed Taylor Fritz kick-started his Miami campaign with a well-earned 7-6(2) 6-3 win over Lorenzo Sonego from Italy.
The American No 1 kept his composure in a gruelling 8th game in the second set, in which he let slip 5 break points, before converting and going on to hold serve for the one hour, 47 minute win.
“It’s huge [because] when you start blowing those [break] opportunities, it almost gets in your head,” said Fritz, who improved to 11-5 in 2025. “He had no break points, and you feel like he would get one and break you; matches always happen like that, but credit to him. He didn’t miss a first serve when he was down in a game.”
Fritz will face Canada’s Denis Shapovalov in the 3rd round, after the 27th seed edged Argentine qualifier Thiago Agustin Tirante, 6-3 6-7(1) 7-6(3).

20-year-old Coleman Wong from Hong Kong notched up the biggest win of his career on Saturday, stunning 13th seed Ben Shelton 7-6(3) 2-6 7-6(5), and snapping the American’s 14-match streak in opening rounds at ATP Masters 1000 and Grand Slam events since the start of the 2024 season.
After an early exit in Indian Wells, Frances Tiafoe moved back on track on Saturday with an opening win, his 50th win at this level, with a 7-5 7-6(5) result against Spain’s Alejandro Davidovich Fokina.
Tiafoe will next meet 17th seed Arthur Fils from France, who led lucky loser Gabriel Diallo 6-4 2-3 before the Canadian retired with an ankle injury.
Andrey Rublev became the latest upset victim on Saturday night, with Belgium’s Zizou Bergs knocking the Russian out, 7-5 6-4.
Bergs will seek to score another upset against Matteo Berrettini, after the Italian opened his campaign with a 4-6 6-3 6-3 win against France’s Hugo Gaston.
