Cameron Norrie is through to the third round of the Rolex Monte-Carlo Masters after a hard-fought victory over Hungary's Marton Fucsovics.
The Briton clinched a 7-6, 6-3 victory in a match which lasted an hour and 45 minutes and will now face Italian qualifier Lorenzo Sonego for a place in the quarter-finals.
There was good news, too, for compatriot Jamie Murray, who along with his Brazilian partner Bruno Soares, made it through to the last eight in the men's doubles with a 7-6, 6-7, 10-8 win over Ivan Dodig and Edouard Roger-Vasselin.
Kei Nishikori is out after losing to Pierre-Hugues Herbert 7-5, 6-4.
The fifth-seeded Japanese player, who lost to Rafael Nadal in last year's final, failed to convert any of his 10 break points against Herbert.
The unseeded Herbert will next play ninth-seeded Borna Coric of Croatia.
Sixth-seeded Stefanos Tsitsipas also advanced to the third round, beating Mikhail Kukushkin 6-3, 7-5.
