EASTBOURNE, England – Swiss teenager Belinda Bencic won her first title by beating Agnieszka Radwanska 6-4, 4-6, 6-0 Eastbourne final on Saturday, enhancing her burgeoning reputation ahead of Wimbledon.

The 18-year-old Bencic won on grass in windy conditions on the south coast to deny the ninth-seeded Radwanska a second title at Eastbourne.

Watched by compatriot and mentor Martina Hingis, Bencic covered her face in her hands after driving a forehand winner past Radwanska on the first match point.

Bencic, ranked 31st, won the girls' singles title at Wimbledon in 2013, and previously lost two WTA finals, including one on grass at 's-Hertogenbosch this month.

Radwanska, the 2008 champion, was looking to win the same tournament twice for the first time.
