The 23-year-old US-based Czech will be the underdog when she faces world number two Ons Jabeur. Win or lose, she will certainly catch the eye. At every changeover, Bouzkova reaches for an outsized, jet-black water bottle which requires both hands to lift. The 'Bouzie Bottle' boasts a giant sticker with the words 'From Prague to Florida...to a court near you'. "We bought it from a girl in Florida. I used the original one for three years and now I always just look at Amazon and buy a new one," said Bouzkova who has been using a giant bottle for a decade. "In fact, I can't even imagine playing without one now."
