Former world number one Caroline Wozniacki failed to defend her e-Boks Open title in Copenhagen after she went down to a 6-4 6-4 defeat by Angelique Kerber.
Danish star Wozniacki had won the previous two titles here and was the slight favourite going into Sunday's final against second seed Kerber in front of a home crowd.
Neither player was entirely convincing on their own serve although Kerber enjoyed more success.
There were 10 breaks of serve in total, of which Kerber converted six, and the German won through in an hour and 38 minutes after being superior all round.
It was Kerber's second WTA title and she remains unbeaten on indoor courts in 2012.
Kerber, who saved two match points during her quarter-final win, suggested the partsan crowd had actually worked in her favour.
"It was amazing to play in front of this crowd, even though most of them supported Caroline. It was a great atmosphere and it was good fun to play.
"And I felt like I had nothing to lose. If I lost the match, it's okay against her. It made me take more chances and I'm glad it worked out."
Wozniacki looked to the future as she played down defeat.
"You always want to win - yes it's disappointing to lose, but it's not a disaster," she said.
"You lose matches sometimes, and today was one of those times. There's a new match and new tournament coming, so you go on."
