Overview
- Both top seeds dropped a set on Thursday before advancing, with Jannik Sinner ending his Masters 1000 set streak against Tomas Machac and Carlos Alcaraz outlasting Tomas Martin Etcheverry.
- João Fonseca beat Matteo Berrettini 6-3, 6-2 to make his first Masters 1000 quarter-final and become the youngest Monte Carlo last-eight player since 2005.
- Alexander Zverev defeated Zizou Bergs to set up a meeting with Fonseca, while Sinner faces Felix Auger-Aliassime after Casper Ruud retired and Alcaraz meets Alexander Bublik.
- Earlier in the week, Matteo Berrettini stunned Daniil Medvedev 6-0, 6-0, with Medvedev smashing his racket and receiving a code warning in one of the rare double bagels against a top-10 player since rankings began in 1973.
- Sinner can return to world No. 1 with a title here, a possibility heightened by his light clay points load and a quarter-final field that also features local breakthrough Valentin Vacherot.
