Keys is too hot for Wozniacki
Madison Keys beat Caroline Wozniacki in straight sets to win the Charleston Open - her first title on clay.
The American, 24, won 7-6 (7-5) 6-3, hitting 54 winners against Danish fifth seed Wozniacki, the 2011 champion.
It marks a fourth career title for Keys and her first since 2017.
The eighth seed beat three Grand Slam champions - Wozniacki, Sloane Stephens and Jelena Ostapenko - en route to victory, as well as reigning Olympic champion Monica Puig.
Wozniacki - playing in her third Charleston final, having finished as runner-up in 2009 - said Keys was "just too good".
World number 18 Keys is the first American winner of the tournament since Stephens three years ago.
Meanwhile, Australia's world number 253 Naiktha Bains has made a formal request to change her allegiance to Great Britain.
The 21-year-old Leeds-born player has told the Women's Tennis Association and the International Tennis Federation of her desire to change playing nationality and compete as a British player in the future.
