Radwanska fails to deliver
Home hope Agnieszka Radwanska could not deliver for an expectant Polish crowd as she lost her semi-final to Alize Cornet at the Katowice Open.
World number three Radwanska raced through the opening set without dropping a game but then lost her way, and despite starting the decider strongly she faltered again on the way to a 0-6 6-2 6-4 loss.
For Cornet, ranked 22nd, it was a remarkable victory, given her slow start and the fact she dropped the opening three games of the third set.
She had turned the momentum of the match right at the start of the second set by stealing successive breaks of serve to lead 4-0, and held her nerve to close that one out.
And while Radwanska looked to have overcome the disappointment of the match's middle set, her level fell as Cornet responded to the challenge to secure her first win in four matches against the 2012 Wimbledon runner-up.
Cornet will contest her eighth career final on Sunday, seeking a fourth title. She was a runner-up to Venus Williams in Dubai in February.
Italian Camila Giorgi and Spaniard Carla Suarez Navarro lined up in the second semi-final, looking to join Cornet in the tournament's showpiece match.
Unseeded Giorgi came through that exchange, beating her third-seeded opponent 7-6 (7/2) 6-4.
The final sees a second career meeting between Giorgi and Cornet, the first having come in January at the Australian Open where French player Cornet earned a tight three-set victory.
