World No. 2 Jannik Sinner has defeated Jiri Lehecka 6-4, 6-4 to lift the Miami Open title and complete the Sunshine Double without dropping a set.
Lehecka, appearing in his maiden Masters 1000 final, had been impressive throughout the tournament, holding serve consistently and saving multiple break points before the final.
However, Sinner immediately took control of the contest, breaking early and dictating play with his aggressive baseline game.
Despite weather interruptions, the Italian maintained his composure and closed out the match to secure one of the biggest titles of his career.
The victory makes Sinner the eighth male player in history to achieve the Sunshine Double, following his earlier triumph at Indian Wells.
He has now extended a remarkable streak of 34 consecutive Masters set wins, joining an elite group that includes Novak Djokovic and Rafael Nadal as only the third man to win three straight Masters titles.
He also becomes the first player to accomplish this feat without losing a set across all three events.
Lehecka, meanwhile, enjoyed a breakthrough run, including wins over Taylor Fritz and Arthur Fils on his way to the final.
Although he showed resilience and improved on their previous meeting, Sinner’s power and consistency proved decisive once again.
Sinner’s dominant run in March marks a strong turnaround after earlier setbacks this season, including a semi-final loss at the Australian Open and a defeat to Jakub Mensik.
The result moves him within striking distance of world No. 1 Carlos Alcaraz in the ATP rankings, with both players enjoying strong seasons but yet to meet this year.
