Czech 17-year-old Marketa Vondrousova won her first WTA Tour title on Sunday, beating Anett Kontaveit of Estonia 6-4, 7-6 in the Biel Ladies Open final.
Vondrousova was playing in only her second ever WTA Tour event, but came all the way through qualifying to win the tournament in Switzerland.
The teenager won eight matches in total and did not drop a set in the main draw, as she became the youngest winner of a WTA title in almost two years.
Against the world 99 Kontaveit, the 233rd-ranked Vondrousova produced a stunning display full of wickedly disguised drop shots and whippet-like speed across the court.
One point at the start of the second set left Kontaveit gasping in disbelief as Vondrousova hurtled from the baseline to somehow retrieve what was a pretty perfectly placed drop shot.
After her victory, Vondrousova said: "It's the biggest win of my career, because I'd mostly played smaller tournament.
"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."

The leftie Vondrousova, whose game is based on creating angles and clever shotmaking rather than brute force, will move up 116 places to 117 in Monday's rankings.
She will now travel to Florida where she is part of the Czech Republic Fed Cup team that is taking on the USA this weekend. If Vondrousova can move her ranking up to inside the top 100, she will earn automatic entry to the grand slams, with French Open and Wimbledon on the horizon.
