World number 233 Marketa Vondrousova won her first title on Sunday when the 17-year-old defeated Anett Kontaveit of Estonia 6-4, 7-6 (8/6) in the Biel/Bienne final in Switzerland.

The Czech teenager came through qualifying at the hard court event and knocked out top seeded compatriot Barbora Strycova in the semifinals.

"It's the biggest win of my career, because I'd mostly played smaller tournaments," said left-hander Vondrousova, who was playing in just her second main draw on the WTA Tour.

"This was one of my first big tournaments, and I was injured in my left elbow for a lot of last year. I had to do a lot of fitness, which helped me become a better mover. Now I'm playing really great.

"At first, I asked for a qualifying wildcard because I wasn't sure if I could get in without one. Once I got into qualies, I almost lost my first match, but I got better and better from there."
