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.
Lucky Number 15
Over the weekend, Mouratoglou Academy hitting partners Serena Williams and Anastasia Pavlyuchenkova took home silverware on either side of the US-México border, with victories in Charleston and Monterrey. Both players have now won the title on their past three visits to the respective tournaments, winning 15 matches on the spin in the process.
Charleston marked the start of the two-month build-up to the French Open. With the clay comes lengthy matches, particularly in the case of Bethanie Mattek-Sands and Anastasia Rodionova, whose drama-filled first rounder in Charleston ended up being the longest match of the year.
At The Movies
Down the years, sport has time and again proved to be an appealing subject matter to the world's great filmmakers. However, for one reason or another, tennis has proven hard to capture in all its glory on celluloid. Until now, that is.
On May 10, Venus and Serena will be coming to a cinema near you. The 99-minute documentary charts the life of two of modern tennis' most iconic players, featuring unprecedented access during the sisters' tumultuous 2011 season.
And if you can't wait until May, not to worry - it was released to rent on iTunes last week.
Kaia Kanepi has not had the best of luck with injuries in recent times. Shoulder and heel injuries restricted her to just 11 tournaments since the start of 2012. On Tuesday in Katowice, she played her first match in six months and it was as if she'd never been away, as she took just 54 minutes to brush aside Polish qualifier Sandra Zaniewska.
Get Well Soon
While Kanepi is back in action, there was some less good news for her fellow Top 50 resident, Heather Watson, who has been diagnosed with glandular fever. Fortunately, the 19-year-old is over the worst of it and is already targeting her return to tour.
One of the WTA's most respected, experienced and popular umpires, Lynn Welch, called time on her career this week. After 20 years of loyal service to the sport, in which she umpired at 60 majors and 12 US Open finals, the Diary wishes Welch all the best for her future endeavors.
