- Angelique Kerber beats Caroline Wozniacki in Copenhagen final
- Second seed Kerber wins 6-4 6-4 at hard court event
- Sara Errani of Italy wins Barcelona Open title
- Ivan Ljubicic bows out of tennis at Monte Carlo Masters
Double defending champion Caroline Wozniacki suffered a shock defeat in the final of the WTA Copenhagen Open as she was beaten 6-4 6-4 by Germany's Angelique Kerber Sunday.
Home favorite Wozniacki had gone into the title match with a 14-0 winning streak at the hard court tournament and victories in the 2010 and 2011 editions.
Kerber, the second seed, had also lost her two previous meetings to Wozniacki, but staged a recovery in each set to claim victory.
She was down 4-3 in the first set before putting a run of three straight games together to take a one set lead and 4-1 in the second.
Five straight games saw Kerber romp to victory in front of the stunned home crowd at the Farum Arena.
"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," Kerber, who won her maiden title in Paris in February, told the official WTA website.
Wozniacki took the defeat in her stride as she moves on to the clay court season.
"Yes, it's disappointing to lose, but it's not a disaster. You lose matches sometimes, and today was one of those times. There's a new match and new tournament coming, so you go on."
In the Barcelona Open, Italy's seventh seed Sara Errani shocked third seed Dominika Cibulkova of Slovakia 6-2 6-2 to win the clay court event.
Errani had also taken the doubles title and had been confident of victory.
"She hits very hard and is very fast, but while she can hit two winners in a row, she can also hit consecutive errors -- knowing that I knew I had to keep up with her pace, keep the ball deep and be very solid, but also stay aggressive," she said.
On the men's ATP Tour, Ivan Ljubicic slipped to a 6-0 6-3 defeat to fellow Croatian Ivan Dodig at the Monte Carlo Masters Sunday.
Ljubicic, 33, was playing the final match of a glittering career in the principality where he now lives.
