The top tennis players in the world, on both the men's and women's sides, are soon to collide at the 2012 Australian Open, with fourth-round action set to take over Melbourne Park on Sunday (i.e. Saturday night into Sunday morning in America).
Roger Federer, Rafael Nadal, Kim Clijsters and Caroline Wozniacki will all be on trial on Day 7, looking to lock down spots in the quarterfinals. None of these superstars has yet dropped a single set at the first Grand Slam of the year.
Nadal and Clijsters will take to the court at Rod Laver Arena in the early action against Feliciano Lopez and Li Na, respectively.
They'll be followed up by Federer's tilt with Bernard Tomic and Wozniacki's waltz with Jelena Jankovic.
The Tennis Channel will carry the action from 7 to 9 p.m. EST, with ESPN2 taking up the mantle from 9 p.m. to 2 a.m.
From 3 to 7 a.m. DirecTV subscribers can catch every match through the Australian Open Experience.
