Weary Wozniacki sent packing by Kvitova

ISTANBUL, (Reuters) – A weary Caroline Wozniacki was  sent packing from the WTA Championships after losing 6-4 6-2 to  powerful Czech Petra Kvitova in her final round-robin match yesterday.
  
The day after the Dane secured the year-end world number one  ranking, she looked mentally and physically drained as Wimbledon  champion Kvitova marched into the semi-finals with a match to  spare in the Red Group.  

Wozniacki, who has racked up 80 matches on the tour this  year, needed to have her blood pressure checked after the first  set and said after that she had nothing left in the tank.  Kvitova was joined in the last four of the season-ending  event by Belarussian Victoria Azarenka who trounced China’s Li  Na 6-2 6-2 to guarantee a top-two place in the White Group, also  with a match remaining.

Russian Vera Zvonareva blew her chance to secure a  semi-final berth when she was ambushed by Poland’s Agnieszka  Radwanska, squandering three match points in a 1-6 6-2 7-5  defeat that had the 11,000 crowd on the edge of their seats.   

Needing a victory to go through from the Red Group,  Zvonareva led 5-3 in the decider before Radwanska staged a  thrilling fightback in the most entertaining set of the  tournament.  Zvonareva must now hope Kvitova beats Radwanska in straight  sets on Friday. Any other result would see the Pole progress.   

After two long three-setters in two days, a win against  close friend Radwanska and a defeat by Zvonareva, Wozniacki  proved no match for world number three Kvitova.  
 
Having lost the first set the Dane quickly went 4-0 behind  in the second and at one point almost missed the ball altogether  on a first serve — the ball spinning embarrassingly off her  racket and bouncing mid-court.  
Some late resistance proved in vain.  
 
“Petra played well,” said Wozniacki who will end a second  consecutive year as number one despite failing to win a maiden  grand slam.
