WUHAN, China: World No.5 Simona Halep downed Madison Keys in the quarterfinals of the Wuhan Open Thursday to book her place in the elite season-end WTA Final for the third consecutive year. Big serving Keys took an early lead in the first set, breaking the Romanian’s serve twice, but was unable to maintain the momentum as Halep equalled and then took the set 6-4. Halep — who turned 25 this week — dropped just two games to take the second set and confirm her place in the eight-player season finale in Singapore. Only world No.1 Angelique Kerber and Serena Williams have so far qualified for the highly lucrative tournament, and the field remains wide open for the remaining five spots. Halep will meet either Kvitova or Briton Johanna Konta in the semifinals on Friday.
