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 »

The 2011 Fed Cup final between Russia, four-time titlist in the last seven years, and the Czech Republic was decided by a doubles clash between Czechs Lucie Hradecka and Kveta Peschke and Russians Maria Kirilenko and Elena Vesnina with the Czech team winning 6-4 6-2 to secure a 3-2 lead and defeat Russia on home soil, which hadn't happened to Russia since 2003.

Petra Kvitova is the hottest player of the moment with her WTA Championships title and the year can also be considered hers, as she won Wimbledon as one of her six titles in 2011.
