Australia's Alex de Minaur overcame a spirited challenge from French veteran Adrian Mannarino on Saturday to march into the 's-Hertogenbosch grass court final with an entertaining 6-4, 6-0 victory.
The world No 6 will next face the tournament's surprise package, Kamil Majchrzak from Poland, who stunned Russia's Daniil Medvedev for his second consecutive win over a top-10 player.
The first semifinal saw the 37-year-old Mannarino, who has won more matches on grass than any other Frenchman, push De Minaur hard but run out of steam against the Australian's superior pace and consistency.

"Super tough... I'm super happy. I found a way after a very tricky start," said De Minaur.
"I knew that I wasn't safe until the last point. I kept that intensity and focus and it made it worth it in the end," he added.
It was the Frenchman who started the stronger, breaking De Minaur's first service game and racing into a 3-0 lead, capitalising on some uncharacteristic errors from the Australian.
Falling behind seemed to galvanise the younger man, who won his next service game to love and broke back immediately after a costly double fault by Mannarino.
The Frenchman delighted the crowd with an extraordinary behind-the-back shot that helped him win another break of serve, but again he failed to consolidate his advantage, pushing a backhand long to give up a break of his own.
The turning point of the first set came at 4-4 when De Minaur showed off his trademark speed to recover a delightful crosscourt drop shot, winning another break of serve and giving himself the chance to serve for the set.
The Australian converted at the first time of asking, helped by two timely aces, to take a competitive first set 6-4.
That seemed to knock the stuffing out of Mannarino, who showed his frustration by smashing a ball into the crowd after the second of three service breaks in the second set.
De Minaur wrapped up the match in one hour 20 minutes.
'VERY INTENSE'
De Minaur, hoping to repeat his 2024 championship win here, was the top seed left in the draw after Majchrzak's shock victory on Friday against world No 4 Felix Auger-Aliassime.
Majchrzak, the world number 76, backed up the best win of his career with another upset as he ground down Medvedev 7-6 (7/4), 6-1 in Saturday's second semifinal.
The Pole claimed the opening set tie-break when Medvedev dumped a backhand into the net, his 23rd unforced error of the match.

Majchrzak secured the first break of the match early in the second set, sending a blistering backhand pass up the line.
An insurance break quickly followed as Majchrzak drilled a return at Medvedev's feet.
Medvedev then contrived to serve three consecutive double faults in his next service game to hand the second set to the 30-year-old Pole.
"It's not going to get any easier," said Majchrzak, looking ahead to Sunday's final.
"Alex is one of the greatest players and obviously he is playing well here on grass. I have played him twice and I've lost twice."
