The WTA season may only be a week old, but there has already been plenty to write home about, including the return of a doubles legend.

Every week there's a lot happening on the WTA - on the court, off the court, by the numbers, even a few tweets... catch up on it all in this week's WTA Diary.

The Fanatics in the Ken Rosewall Arena on Monday evening may not have got the result they were after, but they were certainly not left short changed for entertainment. Aussie favorite Samantha Stosur has not had the best of times on home soil in recent years, but when she saved a match point in the second set tie-break and then forged ahead in the decider against Zheng Jie, it looked like her luck was about to change.

It was not to be. Zheng failed to stick to the script, taking five of the last six games to eke out a 63 67(7) 64 victory. Catch the best bits from this and all the other first round matches on our new video player.

Welcome Back
Prior to her first round match alongside Anastasia Rodionova in Auckland, Cara Black hadn't played any competitive tennis since Wimbledon 2011. Not that you could tell. In her first tournament back, Black, with her eight-month-old son, Lachlan Alexander Stephens, watching on, picked up the 55th doubles title of her career.

Last week also saw Shenzhen make its bow as a WTA stop-off. To the delight of the home fans, Li Na took home the title, but the performance of the week came from Peng Shuai, who managed to retain her usual cheery demeanor in the autograph booth despite the advances of a nightmare-inducing giant orange bear.

Quote Of The Week
Serena Williams may be on top of her game at the moment, but she's not feeling like fun time Serena any more.

"I'm really boring now. I used to be fun. For a fun time, call Serena," Serena said during her title run in Brisbane last week. "Now for a fun time, do not call me - I don't know what happened to me," she said. "I think I just got older and I realized I can't be that fun girl for the rest of my life. I think that's pretty much what it is. I could be the oldest No.1. I don't know how that goes with the funnest."

APPy New Year From The Williams Sisters
Serena may not feel like a youngster, but she's still the WTA queen of cool. So cool, in fact, that Apple chose her and sister Venus to star in the advert for its new 'Do Not Disturb' app. The advert premiered on January 1 and you can check it out here.

Get Well Soon
The tennis gods have not been smiling on Andrea Petkovic in recent times. After missing virtually all of 2012 due to back and ankle injuries, the WTA's favorite twinkle-toed German is now going to miss another two months after undergoing surgery to repair the torn meniscus in her right knee suffered whilst on Hopman Cup duty for her country last week.

While her knee may not be in the best shape, Petko's sense of humor has remained intact:

Eating cake and watching Interpol concert on TV. Hospital isn't too bad after all. And lips and botox face turned out fine btw.
