Since winning Sydney and reaching the final of the Australian Open, Li Na has lost all her opening matches (Dubai, Doha, Indian Wells and Miami), and you know what heals wounds the best, off-court activities such as commercials and photo shoots. The Chinese world No.7 distracted herself by a commercial for the new Beijing Open stadium.

Serena Williams is appearing in the latest Top Spin 4 commercial which is all about exposed curves, black leather clothes, fire and grunts – basically they opted for the old sex sells idea. Serena is apparently in the commercial for this video game because she's "the world's sexiest tennis player", and she's playing against "the world's sexiest tennis gamer". Is it a punishment for Serena, as she didn't play the actual tennis for such a long time?

I'm sure a lot of people love the ad, while I've also read the opinion of a fair share of those who consider it a fail. Here's what one Forty Deuce commenter said:

I'm not sure who this is supposed to appeal to at all. First off, I'm a guy and did not find that ad sexy compared to any other commercial on TV. Second, I am a tennis fan and it had almost nothing to do with tennis. And third, I'm a gamer who was already contemplating buying the game and this told me nothing about it. So, all in all, this was a completely useless advertisement. Good work whoever came up with that.

All the ads aim to grab our attention in some way, and this one is successful in that matter, both visually and auditorily.

When it was revealed that constant flying, especially long flights, played a role in Serena Williams' potentially deadly blood clots in her lungs, in addition to the complications from her foot surgery, the tennis world was shaken.

As spending time flying is an ever-present part of tennis pros' lives, tennis star Kim Clijsters got seriously concerned. The reigning US Open and Australian Open champion pointed out how as a healthy athlete you worry about injuries, and you don't think much about the hazards of frequent flights that your profession requires. Serena's life-threatening health problem alarmed Kim:

Injuries can happen, but to be close to dying…it opened my eyes and made me even more aware of where we need to be. The toughest part for us is flying all over. It's very scary. It's very serious.

Serena Williams spoke to TODAY's Matt Lauer, explaining in detail her recent health state, her pulmonary embolism condition, from the moment she first got hospitalized on February 18. It was an emergency situation because of blood clots in her lungs (her symptoms were a swelling in her leg and breathing problems).

Serena later felt better and the following weekend she had an Oscar appearance, only to end up in hospital the very next day. She had to have a surgery for a grapefruit-size hematoma in her stomach.

Good news is that Serena's career will not be affected, as all the problems were addressed in time. Click on the image to watch the entire interview or click here.

Serena Williams has been out with foot injury for months and in the midst of announcements of her comeback a piece of news broke out about a serious lung condition that required the tennis star to undergo an emergency treatment.

World No.1 Caroline Wozniacki, the one who took the top spot in the rankings from Serena herself, visited the American at her home in Los Angeles. Wozniacki’s report on Serena’s health is positive, saying that Serena looks good and is in good spirits. However, the threats are not over yet and there are things Serena still needs to check on.

Wozniacki was in LA to do a commercial and now she’s already in Indian Wells, where the $4,500,000 BNP Paribas Open is about to start. Wozniacki is No.1 seed at the tournament and as last year’s runner-up she has a lot of points to defend. If she loses in the second round and Kim Clijsters reaches the fourth round, Clijsters will be No.1 again. Another scenario that would change the top-ranked player is that Clijsters advances to the quarterfinals or better and Wozniacki does not get just as far.
