As you know, Women's Tennis Blog is currently on vacation, but I've prepared a number of interesting posts to keep you entertained while I'm away. Even though I won't be updating about tennis happenings in Brisbane, Auckland, Sydney and Hobart, I will give you a bunch of great posts and the first in the series is the compilation of photos of top women's tennis players and their mothers. Enjoy!

Let's start with Caroline Wozniacki and her mother, Anna Wozniacki. Caroline is coached by her father, Piotr, who played professional soccer, but her mother was also an athlete, having played on the Polish women's national volleyball team.

Vera Zvonareva's mother Nataliya Bykova played field hockey and was a bronze medalist at the 1980 Moscow Olympic Games. You can read a very nice story Nataliya herself told a magazine about Vera's early life and the beginnings of her tennis career.

Kim Clijsters' mother is Els Vandecaetsbeek (the blond woman in the picture), a former national gymnastics champion. Kim claims to have inherited gymnast's flexibility from her mother. Read more »

Serena Williams may have suggested a delay in her comeback all the way until spring 2011, but it doesn't mean she's not eager to train. The relentless Serena still has her right leg in the crystal-decorated cast, but that doesn't prevent her from making red carpet appearances and even hitting the tennis court!

Thanks to DeShawn Besabella I learned about two awesome videos showcasing Nike dresses and shoes tailored for Serena Williams and Maria Sharapova for the 2011 Australian Open. The apparel is presented by Nike staff themselves: Nike Tennis product line manager, Alex Chan, and Nike Tennis creative director, Janice Lucena.

Serena probably had the best tennis clothes in the season behind us, along with adidas adilibria representatives, and judging by this sophisticated Australian Open dress and Nike Air Max Mirabella 3 shoes, the year to come will be equally flattering when it comes to fashion. Only that Serena will not have much chance to wear it. It's already confirmed that she'll skip the Australian Open, and no one knows when she'll come back. Serena's white and blue Australian Open dress will probably be worn by Victoria Azarenka. But I suppose the dress would look better on Serena's bustier body.

Nike came up with a peach and light gray color scheme for Maria Sharapova's strap dress, Nike Lunarlon Speed 3 shoes and warm-up jacket. The dress is supposed to have the touches of Australia, especially the back part which should look like a boomerang. The dress is essentially nice, but is not breathtaking or innovative, unlike many past dresses of Maria Sharapova.

It seems that my fashion overviews are hitting the mark. I woke up this morning and saw a message from reader DeShawn Besabella on Twitter that Nike Tennis shared Women's Tennis Blog's review of Serena Williams' 2010 Nike outfits on their Facebook page which has almost 92000 fans.

The overview didn't go unnoticed. As you can see, in ten hours 84 people hit "like" and that's not all. I got an email from another reader, Sam, who told me that he saw how I was advertising Women's Tennis Blog on Nike's Facebook page. Of course, it is not an advertisement, Nike just recognized my overview of their tennis clothes as a good marketing and thought it would be good for their brand that as many people as possible see it.

The word is out that Serena Williams might postpone her comeback until spring 2011 and the tennis star is trying to make the best of a bad situation, personally decorating her cast with Swarowski crystals.

"I hope to be out of the cast and back on the court by spring," Serena said at YSL and Vogue's fashion party in Miami on Saturday night.

Serena hasn't played tennis since Wimbledon 2010 due to a foot injury, and will certainly not going to defend her title at the 2011 Australian Open.

Sam, thanks for pitching me to share this piece of news! (photo via New York Media)
