Miami Open ATP Day Six Round-Up | Sinner and Zverev move through, Mensik falls to Tiafoe and Atmane and Cerundolo dump out Auger-Aliassime and Medvedev

By the end of day six, the ATP Miami Open last-16 will be set in stone. The likes of Jannik Sinner, Alexander Zverev, Felix Auger-Aliassime, Daniil Medvedev, Frances Tiafoe and Jakub Mensik were set to steal the spotlight in Florida.

They did just that with a mix of results seeing top names such as Jannik Sinner come through albeit it was less of an easy school for the others as Felix Auger-Aliassime, defending champion Jakub Mensik and Daniil Medvedev all fell.

First to Sinner who eased past Corentin Moutet. After defeating Damir Dzumhur over the weekend, it was time to face the Frenchman who reached the headlines for completely different reasons this past week.

Danielle Collins supposedly outed him for sending her flirty DM's which she clapped back at and he fiercely denied this in a rebuttal and said that he never followed her in the first place. But on court against Sinner, it was very much a Moutet car crash. Sinner won with consummate ease 6-1, 6-4.

It was all secured in just over an hour 6-1, 6-4 and he now goes through to face Alex Michelsen who saw off Alejandro Tabilo earlier today in three sets. Collins no doubt will have something to say about this on Tennis Channel.

Sinner also creates history as winning 26 consecutive sets at Masters 1000 level moving clear of Novak Djokovic who previously held the record of 24. He had equalled that on Saturday but his easy win helped reach it.

While Alexander Zverev perhaps was lucky to be through as it looked for all the will in the world that he was going to easily see off Marin Cilic but the never say die attitude of the Croat was on full display.

Zverev will be the new World No.3 come what may after this tournament and will now face Quentin Halys who himself managed to see off Kamil Majchrzak shortly before this. He won 6-2, 5-7, 6-4 to reach the Last 16 in Miami and managed to steady the ship well after some early resolve that saw him lose the second set.

But he broke early in the decider to then go 3-1 up which proved to be a deciding catalyst as Cilic was the one in reality out of any of them that was giving away potential break chances. But Zverev still got over the line pretty emphatically.

While there were many shocks otherwise. Jakub Mensik the defending champion fell in a thriller to Frances Tiafoe. The American won through 7-6, 4-6, 7-6 in which he saved two match points and then converted on his seventh opportunity to win through.

He squandered three match points from 6-3 in the third set tie-break followed by three more missed chances. He then looked to be facing defeat himself saving match points at 8-7 and 10-9 before sealing the win after nearly three hours.

He ripped off his shirt amid crowd rapture and applause and he now has 250 tour wins making him the second active American alongside Fritz to reach that mark. Tiafoe is into the fourth round for the fifth time and first since 2022. The World No.20 now faces Terence Atmane.

"I am pretty pumped," Tiafoe said. "I have put in a lot of work to win matches like these, to get myself to be able to hang tough and be tough and to play great tennis three hours in. I was hurting, he was hurting, a day match is never easy. I am super happy with the match. It is one of those even if you go down, it was a great battle."

Atmane upset Felix Auger-Aliassime earlier today 6-3, 1-6, 6-3. Atmane's win over the Canadian was his third against a top 10 player and it harks back to his incredible run last year in Cincinnati where he reached the semi-finals.

Finally the in-form Daniil Medvedev was quelled by Francisco Cerundolo who won through 6-0, 4-6, 7-5 against Medvedev to reach the fourth round at an ATP 1000 for the fourth time in five appearances.

Medvedev ended Alcaraz's run in the semifinals at Indian Wells after winning Dubai and he only lost to Sinner but this time he ran out of gas and steam and Cerundolo took advantage.

“I felt good in my first-round match here, and now I feel way better,” said Cerundolo. “I’m recovering that confidence. The level was there, I was just trying to find it. But now, the Round of 16, so hopefully I can keep it up.”

“It was a great match, super tough. It was my first match against Daniil. He’s probably one of the only guys on Tour who I have never played. I didn’t know what to expect. He has had a great year so far, so I didn’t expect to be up 6-0 in the first set and a break up in the second.

“Suddenly he started playing super good. But I kept believing and stayed there in the match. In the third set, it was a really good set from both and it ended up my way.”
