Ajla Tomljanovic takes on the challenge of beating Serena Williams in 3 sets at the US Open tennis championships. Her father is a handball champion who plays for Croatia and wanted his daughter to take up handball. Ajla stuck to tennis and seemed oblivious to the crowds applauding her opponent's every point as she won 6-1 in the last set after a tie breaker in the second set. Ajla plays for Australia at the US Open.
