SINGAPORE — Agnieszka Radwanska rallied past an exhausted Garbine Muguruza to book a maiden appearance in the WTA Finals title match with a 6-7(5) 6-3 7-5 victory over the Spaniard in a classic encounter on Saturday.
The Pole used all her guile and defensive skills to see off the powerful 22-year-old, setting up a showdown against Petra Kvitova, who stunned Maria Sharapova 6-3 7-6(3) in the second semi-final.
"I didn't know I could come back after that first set," world number six Radwanska said in a courtside interview.
"It was a great match from the beginning to the end, lots of ups and downs, so many rallies and a lot of running.
