Which rising star - Coco Gauff, Sofia Kenin, Belinda Bencic, Marie Bouzkova - had the best August? Your votes will decide.

Kenin and Gauff, a pair of Americans, each had highlight results in the month of August, while Bencic and Bouzkova each reached the biggest semifinals of their careers to date at a Grand Slam and Premier 5 event, respectively. 

Kenin scored wins over a World No. 1 in back-to-back weeks, as she defeated Ashleigh Barty in Toronto and Naomi Osaka in Cincinnati, while her 15-year-old compatriot made another splash at a Grand Slam with a third-round showing at the US Open.
