Alexander Zverev advanced into the quarter-finals of the Rosmalen Grass Court Championship following his win on Wednesday.
The second seed made short work of Adrian Mannarino, winning 6-2, 6-3 in just 55 minutes on the grass courts of s'Hertogenbosch.
The German converted his two break points in the opening set and closed it out at the first opportunity.
While Mannarino would bounce back with a break of serve in the second set, Zverev would turn on the class and win the final three games to move into the last eight.
Zverev will face Frenchman Julien Benneteau in the quarter-finals, who came back from a set down to defeat Nicolas Mahut 3-6, 6-2, 6-2 later in the day.
Elsewhere, fourth seed Gilles Muller defeated Andreas Seppi 7-6(5), 6-4 and eighth seed Aljaz Bedene eased past American Ernesto Escobedo 6-3, 6-4.
