TOWELING ONRemember that instant-classic Dunlop endorsement that saw Dominika Cibulkova nude in a forest with some strategically placed foliage?  It's well known that she's fond of showing off her genetic assets, and the same is true as she touts her new "Pome!"-branded  towel.

COUNTESS CHOCOLAT  Meanwhile, Maria Sharapova teases this week that her Sugarpova brand is leaning into the choco-sphere. I myself recently had a delicious paprika-meets-BBQ potato chip variety from another brand. What flavor of chocolate would you like to see her put out?

AERO STYLE  Serena Williams' fashion choices of late have been duplicitous perhaps. But in truth, who doesn't go to the airport like this anymore, while saving the sartorial goods for the red carpets of the world? Tennis stars: They're just like us. Sometimes.

RAD-SWANK-STA  Not only did Agnieszka Radwanska seize on a golden opportunity to show the Serena-less field how a ninja plays peak tennis at the WTA's year-end championship. She also landed a shiny new Lexus ride from her auto-making sponsor. Not a shabby post-June showing for one who suffered a dreary early-2015 season.
