After overcoming a thigh injury and rallying to beat Venus Williams in an Australian Open quarterfinal, American Madison Keys has a chance to become the eighth woman to beat both Williams sisters in a tournament, when she plays Serena in the semis.
Jim Caple spent Australia Day watching three American women win their Australian Open matches, wandering the grounds at Melbourne Park and, of course, listening to a little "Down Under" by Men at Work.
Not only is the 34-year-old American back in contention at a major, but after beating Agnieszka Radwanska in the fourth round, a resurgent Venus Williams will take on Madison Keys, the protege of her old rival Lindsay Davenport.
Madison Keys upset two-time Wimbledon champion Petra Kvitova after Madison Brengle knocked out Coco Vandeweghe on Saturday. And that means there are four Americans in the final 16 at the Australian Open.
It's no secret Venus and Serena Williams have changed the game of tennis. But 2014 will show further evidence of their influence on the court, as an even more diverse group of American women hits the pros.
