I watch more WTA than ATP, so my observations are from the WTA players.
Osaka does a little dancing on her tip toes and slaps her left thigh. On almost every serve she holds the ball up to her opponent on her serve, almost to indicate new balls.
Jo Konta, bounces the ball three times with very elongated bounces on her serve
Azarenka
used to sound like an owl when she hit the ball, she has since stopped doing that.
Kenin struts and stomps around the court when she walks.
Coco Gauff says "come on" after almost every shot
Errani and Sorribes-Tormo both say "Eh" when the hit the ball. I think it's a Spain thing
Kvitova gives a stadium shaking roar after winning a big point
Halep seems to have grunts that last until the ball is well on her opponent's side of the net
Ons Jabeur yells Vamos even though she's Tunisian
Yep, big WTA fan!
