Paris: Top seed Novak Djokovic outclassed Jan-Lennard Struff to become the first man to reach the French Open quarter-finals for 10 successive seasons at Roland Garros on Monday.
World number one Djokovic continued his bid to hold all four Grand Slam titles simultaneously for the second time by thrashing Germany’s Jan-Lennard Struff 6-3, 6-2, 6-2.
The 32-year-old will now face either ninth-seeded Italian Fabio Fognini or fifth seed Alexander Zverev.
On the other hand, Kei Nishikori set-up the toughest challenge on a clay court — facing Rafael Nadal.
Japanese seventh seed Nishikori came back from 1-4 and 3-5 down in the final set to beat Benoit Paire of France and set-up a Roland Garros quarter-final clash against Nadal.
Similarly, defending champion Simona Halep reached her fourth French Open quarter-final with a 45-minute thrashing of Polish teenager Iga Swiatek in the fourth round.
Halep will face either American 17-year-old Amanda Anisimova or Spain’s Aliona Bolsova for a semi-final place.
