Day Four at the Rolex Monte-Carlo Masters delivered one of the most shocking results of the season and a memorable moment for the home crowd.
Italian wild card Matteo Berrettini stunned fans with a ruthless 6-0, 6-0 demolition of seventh seed Daniil Medvedev in just 49 minutes
Meanwhile, local boy Valentin Vacherot sent the Monte-Carlo crowd into ecstasy by upsetting fourth seed Lorenzo Musetti in straight sets
Elsewhere, Alexander Zverev had to fight back from the brink, while several big names fell as the draw opened up, and my only takeaway is that Alcaraz and Sinner are so far ahead of the rest on clay that they’re basically just making up the numbers.
Here are the key results and quick recaps from Day 4 in Monaco.

Quick Recap
Matteo Berrettini (WC) def. Daniil Medvedev (7) 6-0 6-0
The biggest shock of the day and probably one of the most stunning results we will see during the season, as Matteo Berrettini delivered a ruthless double bagel against seventh seed Daniil Medvedev in just 49 minutes.
The Italian wild card was near-perfect, missing almost nothing, while Medvedev (playing his first clay match of 2026) looked completely lost and failed to win a single game.
Berrettini called it one of the best performances of his career. While Meddy went viral for his racket smash.
Alexander Zverev (3) def. Cristian Garin (Q) 4-6 6-4 7-5
Alexander Zverev survived a major scare in his first clay match of the season. The World No. 3 trailed 0-4 and 2-5 in the deciding set but rallied dramatically, saving three break points in a marathon final game to win 4-6, 6-4, 7-5 after nearly three hours.
Zverev admitted his level “was not there at all” but was relieved to grind out the victory. He’ll face Zizou Bergs in the next round.
Zizou Bergs def. Andrey Rublev (13) 6-4 6-1
Another strong upset as Belgian Zizou Bergs dominated 13th seed Andrey Rublev, winning the last nine games after a tight first set.
Bergs looked sharp and confident on the clay, booking his place in the third round, while Rublev does seem somewhat of a spent force these days.
Joao Fonseca def. Arthur Rinderknech 7-5 4-6 6-31
19-year-old Brazilian Joao Fonseca continued his impressive Monte-Carlo debut. He became the youngest player to reach the third round here since Rafael Nadal and Richard Gasquet in 2005.
Fonseca will now take on the in-form Matteo Berrettini, and his win prevents a Vacherot v Rinderknech final.
Valentin Vacherot def. Lorenzo Musetti (4) 7-6(6) 7-5
Local favourite Valentin Vacherot pulled off a big upset by defeating fourth seed Lorenzo Musetti in straight sets.
The 24-year-old from Monaco showed composure in front of his home crowd, saving a set point in the first-set tiebreak, and after failing to serve it out when leading 5-4 in the second, he rebroke and delivered on the second time of asking.
Musetti is way off the pace this season, looks badly out of match rhythm, and his stay in the top 10 looks to be over soon.
