Just like Adidas for Ana Ivanovic, Fila opted for navy for the upcoming French Open, one of Fila's signature colors which perfectly suits the red clay. The contrast is provided by pink and white. The Summer 2013 Baseline collection features various types of shirts, two versions of the Summer Baseline dress, skorts in white, pink and navy, a hooded jacket and matching pants, wristbands and a pink visor.

Jelena Jankovic, the most recognizable face of Fila, will wear the dress with thick straps, racer back and laser cut mesh overlay on upper back and skirt. Other high-profile Fila representatives Julia Goerges and Nadia Petrova are expected to sport the separates – the skort and tank – Goerges in pink and Petrova in navy.

Ana Ivanovic followed her successful weekend in Stuttgart, during which she scored great victories over Top 2 German WTA stars – world No.6 Angelique Kerber and world No.28 Mona Barthel – in the Fed Cup World Group Play-offs (even though the Serbian team eventually lost to Germany 2-3), with a good start at the Porsche Tennis Grand Prix tournament in the same city, also on indoor clay and also against a high-profile German player, this time Andrea Petkovic, who is trying to come to terms with injuries.

Ivanovic beat Petkovic 6-3 6-2 in the first-round match and will next face eighth seed Nadia Petrova, who beat German Dinah Pfizenmaier 7-6(2) 6-4. If Ivanovic gets past Petrova, which she managed to do in four of their last five meetings, three of which were on clay, she will have a potential clash with top seed Maria Sharapova in the quarterfinals. (photo: sr_cranks)

Just as we said that the Dubai draw opened up for titleholder Agnieszka Radwanska with withdrawals of Victoria Azarenka and Serena Williams, the Pole went out to Petra Kvitova 6-2 6-4 in the quarterfinals, who has now recorded her first Top 5 win since her Wimbledon-winning 2011 season. Despite producing 38 unforced errors to 37 winners, Kvitova was better than Radwanska, whose numbers were modest six winners to five unforced errors. In the semifinals, the sixth-seeded Kvitova will play eighth seed Caroline Wozniacki, who battled past Marion Bartoli 4-6 6-1 6-4. The semifinal will be a clash of Top 2 players from the WTA rankings at the end of 2011.

The other Dubai semifinal will feature members of the top-ranked doubles pairing, Sara Errani and Roberta Vinci. The fifth-seeded Errani, who is 4-2 all-time against Vinci in singles, recovered from suffering a second-set bagel to defeat Nadia Petrova 6-4 0-6 6-3, while Vinci is enjoying one of the best weeks of her career, having recorded two straight Top 10 victories: against world No.6 Angelique Kerber on Wednesday and today against world No.9 Samantha Stosur 6-2 6-4.

At the 2013 Qatar Total Open, Maria Sharapova has a chance to overtake Victoria Azarenka as the No.1 WTA player and win an extra Diamond Ball trophy if she goes all the way to the title. The Russian started off well, with a comfortable 6-3 6-2 victory over Caroline Garcia in the second round.

Sharapova now has a perfect 10-0 win-loss record at the Qatar Total Open tournament, which she won on both her previous appearances, in 2005 and 2008. The organizers are providing an additional incentive to Sharapova if she wins the title for the third time – the Diamond Ball trophy. One more player in the field shares that opportunity with Sharapova, her fellow Russian Nadia Petrova, who also won her today's match, beating Andrea Hlavackova 6-2 6-3.

The No.1 ranking is up for grabs this week, so let's see the obstacles the three contenders have to face to win/retain the position:

• SERENA WILLIAMS' PERSPECTIVE: has to reach the semifinals or hope that Azarenka doesn't make the final and Sharapova doesn't clinch the title;
• VICTORIA AZARENKA'S PERSPECTIVE: has to reach the final for a chance to remain No.1;
• MARIA SHARAPOVA'S PERSPECTIVE: has to win the title and hope that Serena falls before the semis and Azarenka doesn't reach the final.

Serena was also in action today, testing the recovery level of her back and ankle injuries suffered during the Australian Open, and beat Daria Gavrilova 6-2 6-1 in the second round. Daria was barely born when Serena turned pro in 1995! After a first-round bye, defending champion Victoria Azarenka opens her campaign against Romina Oprandi. (photo: © Neal Trousdale)

With a surprisingly straightforward 6-2 6-1 victory over Caroline Wozniacki, Nadia Petrova became the third titlist of the Tournament of Champions – after Aravane Rezai (2009) and Ana Ivanovic (2010, 2011) – which has relocated from Bali to Sofia this year.

It's a nice finish to the season for Petrova, with Tokyo title, WTA Championships doubles and now Sofia singles, her 13th singles career title.

In the round-robin phase of the Tournament of Champions, Petrova beat Maria Kirilenko, Zheng Jie and Tsvetana Pironkova for a perfect 3-0 score in the Sredets Group, then Roberta Vinci in the dramatic semifinal 6-7(8) 6-1 6-4, and finally Wozniacki, for the first time in their last five clashes.

Even though she's come short of the Sofia title, the world No.11 Wozniacki is leaving Bulgaria with a season-ending Top 10 ranking, thanks to her semifinal victory over Tsvetana Pironkova. Let me remind you, Wozniacki started 2012 ranked No.1!

Petrova, who is now coached by Ricardo Sanchez, Wozniacki's coach of earlier this year, will finish the season ranked 12th, one spot higher than her current standing. (photo: © Neal Trousdale)
