Japan-based Fila is also the official footwear and apparel sponsor of the BNP Paribas Open and is providing custom-designed uniforms for event staff and volunteers. Ball kids and line persons also have been outfitted with the brand’s new Cage Delirium tennis sneaker, which debuted last week and is currently available in stores for $100.


Both Isner (ranked No. 11 in the world) and Quarrey (ranked 58th) skipped the early qualifying rounds this week and will face their first opponents this weekend in the second round of the tourney.


Hopefully the two tennis pros didn’t wear themselves out too much during the charity event because they’re slated to compete in this month’s BNP Paribas Open in Indian Wells, Calif.


Helping out the celebrities on the court were Fila-sponsored athletes John Isner and Sam Querrey, who entertained the crowd with singles and doubles play.


Among the featured participants were rapper Ja Rule and actors Colton Haynes, Alan Thicke, Boris Kodjoe and Amaury Nolasco. Also competing in the event was fitness guru Shaun T, who teamed up with Fila last summer to promote everyday exercise.


The athletic brand hosted the event at Westin Mission Hills Golf Resort & Spa in Palm Springs, Calif., to benefit St. Jude’s Children’s Research Hospital.
