On March 25, 2026, the ATP 1000 Miami Masters held the men's singles quarterfinals for the upper half of the draw. Seeds No. 21 Lehecka and No. 28 Fils defeated their respective opponents, successfully advancing to the semifinals from the upper half.

Seed No. 21 Lehecka battled for 122 minutes, winning 7-6(1)/7-5 to end the underdog journey of Spanish youngster Landaluce, who had emerged from the qualifying rounds. This marks Lehecka's second career appearance in a Masters semifinal (2024 Madrid), and his live ranking matches his personal best of No. 16. Lehecka's semifinal opponent will be French player Fils, who endured a 2-hour 47-minute night session battle against Paul. Neither player converted any break points across the 36 regular games of the match. In the decisive set tiebreak, Fils trailed 2-6 but rallied to win six consecutive points, saving four match points, to secure a 6-7(3)/7-6(4)/7-6(6) victory and reach his first Masters semifinal.
