Russian second seed Karen Khachanov suffered a shock defeat at the hands of world No.211 Tallon Griekspoor at the Rotterdam ATP event.
Khachanov, the world No.11, made a strong start before 22-year-old Dutch wild card Griekspoor came fighting back to win 3-6 6-3 6-2.
It was only the second ATP main draw win for Griekspoor, the other coming against Stan Wawrinka at the same stage in Rotterdam last year.

Top seed Kei Nishikori overcame Pierre-Hugues Herbert 3-6 6-1 6-4 on his return from the knee injury which forced him to retire during his Australian Open quarter-final against Novak Djokovic.
Japanese world No.7 Nishikori lost the first set to the Frenchman but bounced back to win and will next face Latvian Ernests Gulbis, who eased past Marius Copil 6-2 6-4.
“It wasn’t easy, as he was playing good tennis and serving well,” Nishikori said.

“I had a little bit of trouble with my return game and couldn’t convert the important points. I just tried to play steady, as I wasn’t playing bad, and I tried to stay aggressive.”
Canadian fourth seed Milos Raonic beat Philipp Kohlschreiber 7-6(8) 7-5 to set up a repeat of his Australian Open second-round match against Wawrinka.
“It’s going to be tough, particularly as our last match was four tiebreaks, across four hours, in Melbourne,” Raonic said.
David Goffin was another seed to bow out, with Gael Monfils his conqueror in two tight sets.
Frenchman Monfils needed one hour and 46 minutes to defeat eighth-seeded Belgian Goffin 7-6 (7-5) 7-5.
Tenth seed Denis Shapovalov overcame Franko Skugor 7-5 6-3 and will play Tomas Berdych in the round of 16 after the Czech ousted Gilles Simon 7-6(8) 6-4.
