Kvitova won $1.75 million by winning every match she played against the world's top 8 players who qualified for the year-end championships, becoming the third player to win the title in her debut appearance (after Serena Williams in 2001 and Maria Sharapova in 2004). Last year at this time Kvitova was ranked #34 but that was before she went undefeated 18-0 in indoor match play and won the 2011 Wimbledon title. Kim Clijsters won last year's title over World #1 Caroline Wozniacki.
Azarenka won $775,000 and will end the year at a career high #3 but continues her elusive search for a major breakthrough title, never having reached a major final. She reached the final by defeating 2011 US Open champion Samantha Stosur and 2011 French Open champion Li Na but losing a dead-rubber 3-set battle with Marion Bartoli (who replaced Sharapova when she withdrew after losing her first two matches).
The championship match was one of the best of the year, with Kvitova starting by playing near-flawless, powerful tennis and rushing to a 5-0 lead in the first set, which she then squandered by losing the next 5 games through spraying errors and tough-minded playing by Azarenka. Kvitova was able to stop the errors and held the 11th game and was able to finally win the first set (on her 5th opportunity) 7-5. The second set was mainly not shown by ESPN, but clearly Azarenka stepped up her play and was able to squeeze out the set 6-4 on her first set point by with a backhand line-clipper winner. The first game of the third set was crucial. Kvitova served by went down 15-40, acing two breakpoints but was able to hold serve with some clutch serving and excellent movement. In the second game, Azarenka was ahead but managed to lose her serve and fell back 2-0. She never was in the position to take a lead for the rest of the match.
Wozniacki's fragile hold on the top spot should come to an end during the first quarter of 2012 as either Kvitova or Azarenka prove the superiority of "big babe" tennis.
