Biel - 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 Ladies Open.
The Czech teenager came through qualifying at the hard court event and knocked out top seeded compatriot Barbora Strycova in the semi-finals.
"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."
