Stefanos Tsitsipas overcame Alexandre Muller in under 90 minutes, with the help of seven aces and 28 winners. Despite suffering one break of serve, he converted four break points on the Frenchman to secure the win.
The world No. 12 will now face Russian Daniil Medvedev, the 5th seed, in what promises to be an intriguing match due to their long-standing rivalry, which began in 2018 when they first faced each other.
That match, won by Medvedev, ended with a heated exchange at the net during the Miami Open.
Since then, Tsitsipas and Medvedev have met 12 more times, with the Russian leading the head-to-head 9-4. This will be their first encounter in 2024. Their most recent match, in the semifinals of the Vienna Open in 2023, was also won by Medvedev, 6-4, 7-6 (6).
