Day 6 of the 2026 Miami Open saw the fourth round spots being decided as Jannik Sinner (2) continued his ruthless form, dismantling Corentin Moutet 6-1, 6-4 in just 71 minutes while extending his record-breaking set-winning streak to 26.
Frances Tiafoe saved two match points in an epic 7-6(11) decider to beat defending champion Jakub Mensik (12) in nearly three hours.
Elsewhere, Terence Atmane pulled off another Top 10 scalp by defeating seventh seed Felix Auger-Aliassime 6-3, 1-6, 6-3, while Francisco Cerundolo stunned Daniil Medvedev (9) with a bagel in the first set before edging a tense 7-5 decider.
Alexander Zverev (3) also advanced after a tough battle with Marin Cilic. With Carlos Alcaraz already out, the tournament looks all but nailed on as Sinner’s title. Full recap and analysis of all the Day 6 action below!

Key Matches
Jannik Sinner (2) def. Corentin Moutet (30) 6-1, 6-4
Sinner cruised in 1 hour 11 minutes, dropping just five points on serve and firing 23 winners. He extended his unbeaten run against left-handers to 21 matches and has now won his 26th consecutive set (surpassing Novak Djokovic’s previous mark of 24). He looks well poised to do the Sunshine Double as there is little resistance left. Next: vs. Alex Michelsen.
Frances Tiafoe (19) def. Jakub Mensik (12) 7-6(4), 4-6, 7-6(11)
A battle lasting nearly three hours as Tiafoe saved two match points in the deciding tiebreak (after squandering several of his own) and converted on his seventh opportunity to win 13-11 in the tiebreak. The American celebrated by ripping off his shirt in front of a raucous home crowd. This was his 250th career tour-level win (making him just the second active American, alongside Taylor Fritz, to reach that milestone).
Mensik, the defending Miami champion who beat Djokovic in last year’s final, is out early and consequently slides down the rankings.
Terence Atmane def. Felix Auger-Aliassime (7) 6-3, 1-6, 6-3
The Frenchman collected his third Top 10 career win after beating Fritz and Rune in Cincinnati last year, as he recovered from a second-set lapse to knock out the Canadian seed in 1 hour 53 minutes. Atmane’s aggressive play proved too much in the decider.
Francisco Cerundolo (18) def. Daniil Medvedev (9) 6-0, 4-6, 7-5
Cerundolo handed Medvedev (fresh off ending Alcaraz’s 16-0 start in Indian Wells) only his second 6-0 set loss of his career in the opener, then held firm in a tense decider (breaking when Medvedev served at 5-6 and winning when the Russian double-faulted on match point).
Cerundolo always plays well in Miami, so it came as no real surprise to see him progress. It wasn’t a particularly good quality match from either player, but Cerundolo’s forehand always seems to deliver in Miami.
Alexander Zverev (3) def. Marin Cilic 6-2, 5-7, 6-4
Zverev looked in control early but had to fight back after dropping the second set to the veteran Croatian (who had upset Brandon Nakashima previously). He broke early in the decider and steadied to advance, but I don’t see him as a threat for the title here in these types of conditions.
Other notable results:
- Ugo Humbert (31) def. Alexander Shevchenko 6-4, 7-6(2). Humbert ended the upset run of the player who beat Ben Shelton.
- Quentin Halys def. Kamil Majchrzak 7-6(4), 6-1. Straightforward after a tight first set; sets up vs. Zverev.
- Alex Michelsen def. Alejandro Tabilo 3-6, 6-3, 6-4. The young American fought back from a set down to earn a dream fourth-round clash with Sinner.
