Key matches

Martin Landaluce (Q) def. Sebastian Korda (32) 2-6, 7-6(6), 6-4

The 20-year-old Spanish qualifier (world No. 151) saved a match point in the second set tiebreak with a backhand winner and then dominated the decider after Korda took medical timeouts for a back problem.

Landaluce became the lowest-ranked men’s quarterfinalist in Miami since 1994 and the first born in 2006 or later to reach this stage at a Masters 1000. Now up to ~No. 103 live, with six straight wins (including qualifying).

It was back to reality for Korda after his big win over Alcaraz, and he looked off the pace because of the back problem he said he felt in Delray Beach. He has been quite injury prone in recent years. Could it be the same safe and effective product that caused his sister and golf pro Nelly Korda to develop blood clots?

Jiri Lehecka (21) def. Taylor Fritz (6) 6-4, 6-7(4), 6-2

Lehecka delivered a master class in the third set, winning five of the last six games with aggressive play. He bounced back strongly after dropping the tiebreak in the second set to claim his first top 10 win in 2026.

Fritz has struggled with several injury issues of late, mainly knee tendinitis, and is well below his prime. Will he play a full schedule? He is on the starting list for Monte Carlo.

Jannik Sinner (2) def. Alex Michelsen 7-5, 7-6(4)

Sinner rallied from 2-5 in the second set, winning 90% of first-serve points (38/42) and extending his Masters 1000 streak of consecutive sets to 28. He admitted he was not at his best baseline but relied on his serve in big moments. This keeps his Sunshine Double bid alive and improves his H2H vs. Americans to 28 straight wins.

Michelsen played quite well, and if his serve was more congruent with someone of his height (6ft 4″) he could have taken this three set.

Other matches

Frances Tiafoe (19) def. Terence Atmane 6-4, 1-6, 6-4. Tiafoe showed mental toughness by escaping 0/40 at 4-4 in the decider.
Tommy Paul (22) def. Tomas Martin Etcheverry (29) 6-1, 6-3. A dominant win without drama for Paul, who advances to his first Miami Masters 1000 quarter-final
Arthur Son (28) def. Valentin Vacherot (24) 6-4, 6-7(4), 6-4. Fils converted his limited return chances effectively, as Vacherot won 85% of his first-serve points.
Francisco Cerundolo (18) def. Hugo Humbert (31) 6-4, 6-3. The Argentine continued his strong Miami history (fourth R16 appearance in five appearances) with a solid straight sets victory. Next: against Alexander Zverev.
Alexander Zverev (3) def. Quentin Halys 7-6(4), 7-6(1). A battle of big servers in which Zverev hit 16 aces, faced no break points and went through both tiebreaks. He extended his streak against players outside the top 100 to 16.
