Mark Philippoussis' Ordina Open run came to an end in the semi-finals when he was beaten 7-6 6-7 6-3 by defending champion Michael Llodra.
The Australian wildcard, who is only ranked 188 after a series of injuries, dropped his serve just once.
And he can take encouragement from his grass-court form as heads to Wimbledon, which starts on Monday.
Frenchman Llodra now plays third seed Mario Ancic in the final after he beat unseeded Czech Jan Hernych 6-4 6-4.
Llodra had suffered seven consecutive first round defeast since March and admitted his run of poor form had started to damage his confidence.
"It's hard to be positive when you don't have any confidence, but I decided to come, and after I won my first round, 7-6 in the third, I have been playing better every day," he said.
"I think I need to have a word with the Federation and get them to have more tournaments in Holland."
