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.
Big In Japan
There were no shortage of shocks on the opening day of the summer hardcourt season, with Japanese qualifier Naomi Osaka causing the biggest when she fought back from match point down to defeat former US Open champion Samantha Stosur in Stanford.
Considering Osaka is ranked outside the Top 400 and had never previously played a WTA main draw match, one would have thought the win over Stosur was the highlight of her tennis career. Not so.
"It's probably the second-best win of my life, the first being when I first beat my sister."
Who said sport and politics don't mix? The WTA's finest have been hanging out with all the political big hitters lately. First, Sara Errani and Roberta Vinci met the Italian PM, then Petra Kvitova was granted an audience with the Czech President, and now Madison Keys is chewing the fat with the mayor of Washington DC.
Meanwhile In Scotland
Eager not to be outdone, Laura Robson was joined by the Duchess of Cambridge for her first outing as ambassador for UK charity SportsAid.
Aces For Humanity
Talking of good causes, here's an update from USANA's Aces For Humanity campaign.
Martina Hingis was named MVP as she helped the Washington Kastles to their fifth World TeamTennis title in six years.
