We can soon start calling our reader Omair a stats expert. After seeing his "Comparative analysis of Top 10 players and their performance at big tournaments in 2011" received so well, Omair eagerly rushed to thrill us with more analysis, this time focusing on the year-end Top 10 players and the ranking of opponents that they beat in 2011 (Part 1) and on the ranking of opponents that beat them (Part 2). Let the tables do the talking!

The table above shows the number of tournaments where a year-end Top 10 player defeated more than one Top 10 player. Petra Kvitova tops here with three tournaments, at two of which she defeated three or more Top 10 players en route to the title (Madrid and WTA Championships). World number one Caroline Wozniacki is the only Top 10 player who did not beat two Top 10 players in a single tournament.

Let's continue with tables showing tournaments won by each Top 10 player and tournaments where the player (though did not end up winning the event) ended up beating two or more Top 10 players.

In the beginning of the year our loyal contributor John Bolan made a prediction of how Top 10 would look like at the end of the season and a lot of readers presented their Top 10 picks in the comments. Now that the tennis 2011 has ended, I thought it was perfect time to ask John to do a comparison of the prediction and the actual season-ending rankings. He was eager to accept my proposal. Continue reading to see the shocking changes over the last 11 months, such as Justine Henin and Dinara Safina not playing any more and Petra Kvitova, who was never even mentioned, joining the elite big time.

On January 8, 2011 the Women’s Tennis Blog published my article "Who will be Top 10 players at the end of 2011?".  My picks were listed with reasons why I chose them. Many fans used the comment section to submit their picks. Now that the year is over, let’s find out how we did.

Most of us only named about 5 out of the 10 Top finishers. The reason that we did so poorly was the injury factor. Five of the top players were injured for most of the year – Justin Henin, Kim Clijsters, Dinara Safina, Serena Williams and Venus Williams. Most of us had at least 3 of these injured stars on our Top 10 list. The most difficult factor in picking the Top 10 is trying to guess who will not be able to play a full season and 2011 was an unusual year with so many of the top stars injured for so long.

No one picked the number 2 finisher – Petra Kvitova. Only one person picked Marion Bartoli and only one picked Andrea Petkovic. These omissions hurt the overall accuracy of our picks. Read more »

Just to note, in the following tables CW is Caroline Wozniacki, PK is Petra Kvitova, VA is Victoria Azarenka, MS is Maria Sharapova, LN is Li Na, SS is Samantha Stosur, VZ is Vera Zvonareva, AR is Agnieszka Radwanska, MB is Marion Bartoli and AP is Andrea Petkovic.

WIN-LOSS RECORD OF THE YEAR-END TOP 10 PLAYERS AGAINST EACH OTHER IN 2011

The win-loss record is in itself self-explanatory, showing who has been the most dominant player - Petra Kvitova. Please also note the number of wins by a player against Top 5 players, especially for Top 5 players.

OVERALL WIN-LOSS RECORD IN 2011

Kvitova is not the leader only in the percentage of wins over fellow season-ending Top 10 players, but is also the leader in yearly win-loss record overall.

During the WTA Championships in Istanbul Caroline Wozniacki secured season-ending number one ranking for the second year in a row, and her golfer boyfriend Rory McIlroy has gotten closer by reaching a career-high world ranking of number two on November 6th. The high-profile sports couple, more and more called Wozzilroy, celebrated their new achievement by posing with hand gestures signifying their rankings. Read more »

I'm regularly reviewing fashion at Grand Slams (take a look at this year's tennis outfits at the Australian Open, Roland Garros, Wimbledon and US Open) and this time I've decided to add the season-ending Championships, as another great tennis stage. The singles field at the $4,900,000 tournament this year played in Istanbul consists of eight players, so only the mere quantity of players significantly reduces the diversity of outfits. Therefore, nothing can outclass Grand Slams as the best stages for all the fashion fun, although some stars had brand new looks prepared for the WTA Championships.

Li Na and Victoria Azarenka are sporting neat outfits, but they are nothing new, we've seen them in previous tournaments. Li is wearing Nike Women's Holiday Smash Classic Top and Pleated Skort. Azarenka already gave a lot of exposure to her Nike Women's Holiday Set Point Graphic Tank and a matching skort during her run to the Luxembourg title and Tokyo semifinals.

Petra Kvitova, another Nike representative, is just like Azarenka wearing purple and grape tones. Caroline Wozniacki is wearing the best of her recent Adidas by Stella McCartney dresses, which she should've worn at the US Open, in my opinion, instead of the similar dress in white. Read more »
