Remember how Maria Sharapova's former coach Michael Joyce recently criticized Caroline Wozniacki's tendency to let go of coaches too easily? Well, the Dane again has a new coach in her team, the 2002 Australian Open champion Thomas Johansson, and he will stick around at least through the US Open, while he's already been working with the Wozniacki camp for a few weeks.

Wozniacki's father explained that they have already set up a plan with Johansson and after Roland Garros Wozniacki will start training with him in Monaco. By the way, the 37-year-old Johansson has another job, as well as a family.

Just like Joyce pointed out in his criticism that Wozniacki needs to give her coaches more time to prove themselves, Johansson said: "We must give it some time. One doesn't make no miracles in such a short time." (source: Tennis.com, photo: © Neal Trousdale)

Kim Clijsters retired from tennis in May 2007, got married in July 2007, gave birth to lovely daughter Jada in February 2008, and then made a historic comeback which included three Grand Slam titles, while in her "first career" she won one. However, the Belgian has now decided to definitely call it quits. At the moment she's not playing due to a hip injury, and she will skip Roland Garros, but she will come back on grass, play the Unicef Open, definitely the Olympics, and then after the US Open, the major whose trophy she's lifted three times, there will be no more competitive courts for Clijsters.

"That will be a special tournament," Clijsters told a press conference at the presentation of StarMeal, a new food concept. "We'll be in the United States with my husband's family. The US Open is the perfect way to say goodbye."

Imagine that Clijsters ends her career by winning the US Open! Do you think it's possible? Remember that she won at Flushing Meadows in 2009 after playing just two warm-up tournaments since returning from more than two years out of sport and even successfully defended the title the following year.

The 2012 US Open starts on August 27.

Our stats analyst Omair is already famous for his statistical articles and now he's inspired Ludolf, another reader of Women's Tennis Blog and fan of tennis numbers, to contribute his take on the WTA rankings, i.e. he compared the actual rankings with the performance of players at the biggest events – Grand Slams and WTA Championships. Enjoy!

The WTA ranking does not rank properly the strength of players in the sense of the ability to win a match or a tournament. The main reason is that it is cumulative and therefore underestimates players without a sufficient number of tournaments. We need to compute an average to avoid this. Moreover, the WTA ranking considers tournaments with weights not depending on the quality of players on them.

To achive the above-mentioned goal it seems to be more appropriate to take the average result from majors and the WTA Championships, the tournaments where the best players are almost always present. By the result of a player we mean the number of her losses (including the rounds which she did not achieve), i.e. 0 for the winner, 1 for the defeated finalist, 2 for defeated semifinalists, and so on. The results for the last 52 weeks are presented in the table, completed by the WTA ranking (after the Australian Open) for comparison.
