Garbine Muguruza defeats Svetlana Kuznetsova at WTA Finals

Garbine Muguruza ended Svetlana Kuznetsova's winning streak

French Open champion Garbine Muguruza ended Svetlana Kuznetsova's winning streak at the WTA Finals on Friday with a consolation 3-6 6-0 6-1 victory.

Kuznetsova finally ran out of steam having already booked her place in the semi-finals, winning just one of the last 12 games as the Spaniard, who was already eliminated from contention after losing her first two matches, finished the tournament with a morale-boosting victory.

After winning the first set, Kuznetsova lost 10 games in a row as 23-year-old Muguruza produced her best performance of the tournament to finish the contest in one hour 34 minutes.

"It was very difficult for me this tournament because I started losing two matches but today I wanted really to go for the victory to feel good for myself and, I did it," Muguruza said after the match.

Kuznetsova has battled jetlag and exhaustion since flying straight to Singapore after lifting the Kremlin Cup last weekend, which saw her leapfrog Britain's Johanna Konta for the final spot in the tournament.

With Serena Williams and Maria Sharapova both absent from the prestigious end of season championship, Kuvnetsova has emerged as the unlikely headline act of the $7 million event, restricted to the world's top eight players.

"To go to the limit, you need to push yourself hard, but I want to do that tomorrow," Kuznetsova said. 

Agnieszka Radwanska will face off against Angelique Kerber in the semi-finals

Kuznetsova will play Dominika Cibulkova in Saturday's semis while the defending champion Agnieszka Radwanska took the final spot after beating US Open finalist Karolina Pliskova 7-5 6-3 and will now face off against world No 1 Angelique Kerber.

"I think I really have nothing to lose at the moment, especially (since) I'm going to play the best player of the season," Radwanska said of the top-ranked German. "She's played incredible tennis this year."
