Jannik Sinner claimed his 29th and 30th consecutive sets at ATP Masters 1,000 events as he cruised past American Frances Tiafoe into the semi-finals of the Miami Open.

The Italian world number two, who broke Novak Djokovic’s 10-year record of 24 on Monday, never looked back after breaking Tiafoe in the opening game – going on to win 6-2 6-2 in 71 minutes.

The world number 20 simply had no response to a dominant dislay from Sinner, who dropped only nine points on serve across the two sets.

Sinner, who has won four Grand Slam titles, will face either Germany’s world number four Alexander Zverev or Argentina’s Francisco Cerundolo in the last four.

“I felt like I was serving quite well in the important moments,” said Sinner said on Sky Sports.

“I thought he might be a bit tired because he has had tough matches here a couple of three set matches so I tried to make it physical in the beginning and that helped for sure.”

The other semi-final will pit France’s Arthur Fils against Czech Jiri Lehecka.

Sinner is aiming to become the first man since Roger Federer in 2017 to complete the coveted ‘Sunshine Double’ of winning Indian Wells and the Miami Open in the same year.

The 24-year-old has now reached the semi-finals in four of his five appearance in the Miami Open and triumphed in the tournament in 2024.
