World number 12, Jo-Wilfried Tsonga of France, reportedly tweeted about a thank you letter he received from a ball girl he helped during last year's Australian Open. Notably, Tsonga had escorted the girl off the court when he saw her crying after being struck by the ball. “Thank you very much for your letter Giuliana !!! #Remember #AustOpen2016,” tweeted Tsonga along with a photograph of the letter.
