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.
Kimiko Date-Krumm added another achievement to an already remarkable career on Tuesday with a shock win over No.12 seed Nadia Petrova in the first round. At 42 years and 109 days, Date-Krumm became the oldest player ever to win a round at the Australian Open. For the record, she also became the fifth oldest to win a match at any major.
Quote Of The Week
So what's the secret behind Kimiko's lasting success? Eating and sleeping. And lots of it.
"I eat a lot. I sleep a lot," Date-Krumm said after her win over Petrova. "Last night I was in the bed before 10pm. I finished the dinner already at 7.30. Sleep before 10 - just like the kids. Because after the match or after the practice I'm tired, so I need time to recover a lot! So I sleep a lot, I eat healthy foods, I drink a lot. It's a simple life!"
In A Hurry
Any suggestions that Maria Sharapova's injured collarbone and lack of match practice left her vulnerable to an early scare in Melbourne were dispelled in typically stylish fashion on Monday as she thrashed Olga Puchkova, 60 60. Keen not to be outdone by her rival's 55-minute masterclass, Serena Williams was in equally ruthless mood, defeating a helpless Edina Gallovits-Hall by the same scoreline.
Serena's outing wasn't without a scare along the way, though; in the fifth game of the first set, she twisted her right ankle when running wide for a forehand, and remained on the ground for a few minutes before limping back to the chair to have it looked at by the physio.
Maria and Serena may not have been keen to hang around, but the same cannot be said for Garbiñe Muguruza, who required three hours and 20 minutes to see off Magdalena Rybarikova, 46 61 1412, out on Court 13, with the last set alone taking over two hours.
Muguruza's reward for this marathon effort? A clash with Serena Williams.
Caroline Wozniacki is famed for her consistency and watertight defense, and she further enhanced this reputation on Tuesday, committing a miserly eight (yes, eight!) unforced errors during her three set win over Sabine Lisicki.
A few weeks ago the WTA Diary exclusively* broke the news that Maria Sharapova was finally joining Twitter. Well, she's now a signed-up member of the Twitter brigade and chose the first day of the Australian Open to send her first tweet.

Remember Svetlana Kuznetsova? Well, after some time recovering from a knee injury the two-time major winner is back and has rediscovered appetite for tennis. She's also the Diary's dark horse for this fortnight. Sorry, Sveta, this means you're probably going out in the second round.
It Gives You Wings
Victoria Azarenka may be defending Australian Open champion and top of the rankings, but in case she needs an extra lift, she can fall back on her new sponsor: Red Bull. The Belarusian has signed a multiyear endorsement deal with the energy drink company. Apparently she has "a certain swagger."
