Whatever happens on Sunday between Petra Kvitova and Agnieszka Radwanska in the final of the WTA Finals in Singapore on Sunday, history will be made.
In the history of the season-ending tournament for the top eight seeds, it has never happened that a player who lost two matches in the first round has gone on to win the title but the two finalists for Sunday, each lost two matches in the first round.
For Radwanska, it is uncharted territory, as this is the first time she will be making the final while Kvitova is gunning for a second triumph, having won as a debutant in 2011.
Kvitova, two-time Wimbledon champion beat Maria Sharapova 6-3 7-6, while Radwanska battled hard to get past No.3 seeded Garbine Muguruza 6-7 6-3 7-5.
With world No.1, Serena Williams, having pulled out because of injury, many had thought that Sharapova would step up to the plate, especially after winning all the three matches in the group phase.
Sharapova had raced into a 4-0 lead in the second set but the Czech left-hander battled back by taking five straight games. Kvitova leads in the head-to-head clashes against Radwanska 6-2.
In the doubles event, Martina Hingis and Sania Mirza are one win away from claiming a ninth victory on tour this year as they face up against the dangerous pair of Muguruza and Carla Suarez Navarro. If Hingis achieves this victory, it would also be her 50th career WTA doubles win.
