Croatia's Ivan Ljubicic beat home hope Peter Wessels to win the men's title at the Ordina Open in 's-Hertogenbosch.
Ljubicic made it three straight Croatian wins in 's-Hertogenbosch
Second seed Ljubicic needed three sets and two tiebreaks to beat qualifier Wessels - who is ranked 488th in the world - 7-6 (7-5) 4-6 7-6 (7-4).
In the women's final Anna Chakvetadze beat top seed Jelena Jankovic 7-6 (7-2) 3-6 6-3 in a final interrupted several times by rain showers.
Jankovic struggled with an injury and played with a bandaged left thigh.
The 20-year-old Chakvetadze led 5-0 in the opening set but nearly blew it as four rain breaks disrupted her rhythm before she found form in the tiebreak.
I never felt this good before any Wimbledon in the past
Jankovic battled through some apparent discomfort despite Wimbledon being just two days away and levelled at one set all.
But Chakvetadze took the decider to claim her second title of the year.
Wessels had had to complete his semi-final match earlier on Saturday after it was halted on Friday because of darkness.
It was a tight affair, but Wessels beat Antony Dupuis of France 7-6 (7-5) 7-6 (7-3).
But ultimately Wessels was unable to claim a second title of his 11-year career.
"Beforehand I would have been happy to make the final," said Wessels.
"But if you're there and so close, that's bitter."
Ljubicic praised his opponent, saying: "For me it was a very difficult match today. He was serving very well and I had everything to lose.
"I couldn't afford to lose this win even if I know that Peter is a fantastic player.
"He was really unlucky with injuries. But how do I explain everybody that he's not really number 488?
"I feel very good, I never felt this good before any Wimbledon in the past so maybe this is going to be different."
