The Australian, who won this title in 2024, faced just one break point against Bonzi and erased it with a shot that perfectly encapsulated his performance.

Bonzi floated a low backhand slice to the De Minaur's feet and, close to the net, the Australian produced a brilliant drop-volley winner.

De Minaur lifted the ATP 500 trophy in Rotterdam in February and is now looking to become just the second player after Richard Krajicek in 1997 to capture both Dutch ATP Tour titles in the same season.

“I would be very happy if I can maintain this level,” De Minaur said after the match.

"[It gave me ] a lot of confidence because I felt very good out here, and hopefully I can bring the same level tomorrow.

“I had to play at an extremely high level to beat someone like Benjamin. He’s a very good player on this surface. He’s a hell of a competitor.”

De Minaur has now compiled a 19-2 record on Dutch soil since the start of the 2024 season, a stretch highlighted by title runs in ‘s-Hertogenbosch in 2024 and Rotterdam in 2026.

Next up for the Australian is a semi-final meeting with another former champion, 2019 winner Adrian Mannarino. 

Mannarino trails De Minaur 1-4 in their head-to-head, but his lone victory came at this Dutch ATP 250 tournament in 2022.

Meanwhile, Felix Auger-Aliassime's run at Rosmalen was cut short by Kamil Majchrzak, who picked up the biggest win of his career to reach the semi-finals.

World No.4 Auger-Aliassime was the favourite to win the tournament in 's-Hertogenbosch, but instead crashed out as Majchrzak won 6-4 6-3 in just 70 minutes.

"This is definitely the best win of my career," Majchrzak, from Poland, said. "Felix has been at the top for a very long time.

"I knew what to expect. I knew I had to be at my best and be brave in the very big moments. I was very clinical. I was serving pretty well, and I was trying to maintain my [level] from the beginning until the end."
