Daniil Medvedev maintained his winning streak as the Russian advanced into the Western and Southern Open quarter-finals with a straight-sets victory over Grigor Dimitrov.
Top seed Medvedev, who went into the tournament in Cincinnati having just won the National Bank Open in Toronto, saw off his Belarusian opponent 6-3, 6-3 in almost exactly an hour-and-a-half.
The world No 2 was quoted on atptour.com as saying in his on-court interview: “It was tough, especially in the second set. I had four break points before I broke him. I knew I had to continue to push him.
“What makes it tough [on the Cincinnati-Toronto double], it is two weeks in a row against the best players in the world. I am still young, healthy and feeling 100 per cent, so that is why I want to try and do it.”
Medvedev will now face Pablo Carreno Busta, who progressed with a 7-6, 7-6 triumph over Hubert Hurkacz, the conqueror of Andy Murray in the previous round.
Second seed Stefanos Tsitsipas defeated Italy’s Lorenzo Sonego 5-7, 6-3, 6-4 to set up a quarter-final against Felix Auger-Aliassime, who progressed after knocking out fifth-seeded Matteo Berrettini in straight sets.
The third-seeded Alexander Zverev will next face Norway’s Casper Ruud, after respective defeats of Guido Pella and 10th seed Diego Schwartzman, while Andrey Rublev beat Gael Monfils to go through to face Benoit Paire.
