PARIS - Clay was no longer an object of hate for Russian Daniil Medvedev as he stormed into the fourth round of the French Open with a commanding 6-4 6-2 6-4 win against towering American Reilly Opelka.

The rangy 25-year-old has reached two Grand Slam finals on hardcourts but has never hidden his dislike for red dirt, having never won a match at the claycourt Grand Slam in four previous appearances before this year.

But Medvedev has looked in his comfort zone at this year’s tournament in Paris and hit 28 winners and committed just 16 unforced errors against Opelka to stay on course to clinch the world number one ranking.

The second-ranked Russian could topple Novak Djokovic from the top of the standings if he reaches the final in Paris and the Serbian does not.

“Clay in Roland Garros feels great this year,” he told reporters. “Especially Wilson balls.

“Said it from the beginning. I think it’s going to stay till the end of the tournament. As I said after the first round, now I know to beat me, guys have to play good.”

Opelka started strongly and took a 3-1 lead in the opening set but Medvedev then broke the 2.11-meter tall American’s booming serve twice in a row as his opponent committed an array of unforced errors on the Suzanne Lenglen court.

The Russian continued his dominance in the second set as Opelka, who made 36 unforced errors in total, failed to rein in his mistakes and got broken twice more.

Medvedev sealed the match with an early break in the third set and will next meet 22nd seed Cristian Garin.

“It’s definitely never an easy draw to play Reilly,” Medvedev said. “Of course, indoor hard courts would be tougher than outdoor clay courts.

“I think a little bit rainy conditions, wet, heavy court which I totally hate on clay, helped me today.”
