Australia's Alex Bolt has been eliminated from the Rosmalen Grass Court Championships in the Netherlands by Mackenzie McDonald of the United States.
The 25-year-old world No.105 was gallant in defeat but unable to break through against the Californian, falling 6-4 7-5 on a rainy day that saw play suspended for more than two hours.
McDonald will next face Frenchman Jeremy Chardy in the quarter-finals after the world No.72 pulled off a massive upset against countryman Adrian Mannarino, winning 6-4 6-4.
Another French stalwart Richard Gasquet, a two-time semi-finalist at Wimbledon, eased into the last eight after beating world No.76 Evgeny Donskoy 6-2 6-2.
Gasquet, who is competing in the tournament for the first time since 2008, dismantled Donskoy in a little over an hour to set up a quarter-final encounter with Greece's Stefanos Tsitsipas.
"It's always tough to win," Gasquet, the world No.30, said. "The transition from clay to grass is definitely the toughest, and it gets tougher with age."
Tsitsipas, a runner-up at the Barcelona Open in April, earned a hard-fought 4-6 7-6 (8-6) 6-2 win over Tunisia's Malek Jaziri.
Bernard Tomic will face fourth seed Fernando Verdasco while Matthew Ebden takes on Marius Copil to kick off the quarter-final action on Friday before Chardy and Gasquet do battle.
