Jannik Sinner continued his push for a Sunshine Double by defeating Frances Tiafoe 6-2, 6-2 to reach the Miami Open semifinals. The No. 2 seed moved through the match on Stadium Court in one hour and 10 minutes, conceding few opportunities as he advanced to the last four.

Sinner has now won 30 consecutive sets at Masters 1000 events, having bettered Novak Djokovic’s previous record of 24 in the third round. The Italian arrived at Hard Rock Stadium off the back of his BNP Paribas Open title in Indian Wells and was competing for a second Miami trophy after an excellent March run.

The momentum shifted further in Sinner’s favor when world No. 1 Carlos Alcaraz exited in the third round to Sebastian Korda, leaving Sinner as the tournament favorite. On his way to the quarterfinals, Sinner beat No. 30 seed Corentin Moutet and Alex Michelsen in straight sets to set up a sixth career meeting with Tiafoe.

Tiafoe, a former Top 10 player, earned his first win over Sinner in 2021 in Vienna and had produced a key victory at this tournament when he dethroned defending champion Jakub Mensik in the third round, toppling the No. 12 seed in a third-set tiebreaker. He followed that with another three-set win over Terence Atmane to reach this stage.

Against Sinner, Tiafoe found himself under pressure early, losing serve in the match’s opening game. He struggled to trouble Sinner’s serve and did not take the Italian to deuce until he trailed by a set and a break. Sinner held his serve, added an insurance break and moved to serve for the semifinal berth.

Sinner surged to triple match point with a well-struck backhand and converted the first to close out the victory, reaching the semifinals in just over an hour.

Arthur Fils produced a late-night escape at the Miami Open, saving four match points to defeat Tommy Paul 6-7 (3), 7-6 (4), 7-6 (6) in a quarterfinal that featured no service breaks. The 21-year-old Frenchman rallied from 6-2 down in the deciding tiebreak, running off the final six points to complete a two-hour-and-49-minute victory.

There were no breaks of serve across the contest, and Fils’ only break point of the night came at 5-6 in the third set, when Paul’s 40-0 lead on serve disappeared. Paul, who played aggressively and matched Fils’ heavy, spinny shotmaking with bold ball striking, overcame a match point to earn four of his own before the match turned.

Fils’ comeback caps a strong return from injury. Last year he was the only player to reach the quarterfinal stage at the season’s opening three 1000-level tournaments, but a stress fracture sustained during a five-set win over Jaume Munar at Roland Garros forced him to withdraw from his home major and limited him to a single appearance in Toronto until he returned at Montpellier last month.

Since coming back, Fils has posted 13 wins in 17 matches, five of them against Top 30 opponents. He finished runner-up to Carlos Alcaraz at the ATP 500 in Doha, and matched his 2025 Indian Wells last-eight run ahead of his deeper run in Miami. In the third round he produced “the best match I ever played in my life” with a 6-0, 6-1 victory over Stefanos Tsitsipas.

Fils had 2,935 points on his ranking following last year’s French Open. The win over Paul is projected to raise him to 1,640 points in Monday’s rankings. Reaching the final would be worth 1,890 points, while lifting a maiden 1000 crown would move him to 2,240 points. He will face Jiri Lehecka in Friday’s semifinal.

Jiri Lehecka reached his second career Masters 1000 semifinal Wednesday, the 24-year-old Czech defeating Spanish qualifier Martin Landaluce 7-6 (1), 7-5 at the Miami Open.

“I knew what to expect,” Lehecka told Prakash Amritraj. “I knew he was going to play well and I knew that the level will be there. I did everything I could to stay in the match and work my way through the difficult situations.”

Lehecka had to navigate tense endings to both sets. Landaluce forced a tiebreak in the first set and made a late surge in the second, but Lehecka’s experience proved decisive as he closed out the match.

“These were the crucial moments where I feel I showed that I’m a little bit more experienced and I also did some good shotmaking there.

“The thing I saw about him was he really was the one who was winning the points. He went for it, he was very aggressive. It wasn’t just that some of the guys didn’t feel good or had a bad day. He was the one who really punished them and was aggressive going into it.”

Lehecka, the tournament’s No. 21st seed, will await the winner of the quarterfinal between Tommy Paul and Arthur Fils.

“I think both guys are playing with a little more spin if I compare them to Martin today, but they’re more experienced,” said Lehecka, the tournament’s No. 21st seed. “Both of them are great competitors. Tommy’s playing on home soil. Arthur’s in great form.

“We’re going to see. I’m very curious how that match is going to go, but I think whoever wins, on this court in Miami, I have the weapons to challenge them.”

Lehecka last reached a Masters 1000 semifinal in 2024, a run that coincided with a back injury that later sidelined him for three months. The memories from that period remain vivid for the Czech.

“I have memories I will never forget from that week: good ones and bad ones, as well,” Lehecka told Amritraj. “I will never forget how I played Rafael Nadal in his last match in Madrid. That was huge. Every time someone is cheering against me, I think how I played Rafa in Madrid and how there were 13,000 people against me. My team were the only ones hoping I would win any point!”
