BIEL, Switzerland (AP) Aged just 17, Marketa Vondrousova won her first WTA Tour title on Sunday, beating Anett Kontaveit of Estonia 6-4, 7-6 (6) in the Biel Ladies Open final.
The 233rd-ranked Czech clinched the first edition of the Swiss indoor hard-court tournament when Kontaveit netted a forehand under pressure from another powerful ground stroke.
Vondrousova did not drop a set in the main draw after advancing through three rounds of qualifying. She beat top-seeded fellow Czech Barbora Strykova in the semifinals to reach her first final on tour.
On Sunday, the left-handed Vondrousova overcame double-fault problems on her serve to save 13 of the 14 break-point chances that 99th-ranked Kontaveit had.
