Jannik Sinner extended his record for the most consecutive sets won at ATP Masters 1,000 events to 28 as he reached the quarter-finals of the Miami Open.
The Italian world number two, who broke Novak Djokovic’s 10-year record of 24 on Monday, beat American Alex Michelsen 7-5 7-6 (7-4).
Four-time Grand Slam winner Sinner came from 5-2 down in the second set to secure a meeting with American 19th seed Frances Tiafoe.
Sinner has won the past two Masters 1,000 tournaments – in Paris in November and Indian Wells this month – without losing a set.
Sinner, who won the Miami Open in 2024, is the only former champion still in the tournament.
He is set to reduce the gap to world number one Carlos Alcaraz in the rankings following the Spaniard’s third-round defeat by Sebastian Korda.
Sinner could face world number three Alexander Zverev in the semi-finals.
German Zverev defeated Frenchman Quentin Halys 7-6 (7-4) 7-6 (7-1) to set up a quarter-final meeting with Argentine Francisco Cerundolo.
