2015 Australian Open TV coverage and schedule for Wednesday matches
Novak Djokovic and Serena Williams will be in action for the quarterfinals of the Australian Open on Wednesday.


Men’s top seed Novak Djokovic will be taking on No. 8 seed Milos Raonic to decide the other men’s semifinal spots. Djokovic is coming off a dominant Round of 16 victory over Gilles Muller and certainly has more left in the tank than Raonic, who was pushed to five sets against Feliciano Lopez the same day.
In the other men’s matchup, No. 4 seed Stan Wawrinka will face No. 5 seed Kei Nishikori. Wawrinka had his hands full with unseeded challenger Guillermo Garcia-Lopez in the Round of 16, dropping one set and being pushed to an extended tiebreak in the fourth set, but he came out ahead in the end. Nishikori dominated No. 9 seed David Ferrer in his matchup, winning in straight sets.
For the women, top seed Serena Williams will be in action against No. 11 Dominika Cibulkova. Williams dropped a set in her Round of 16 matchup, but recovered and took the following two. She’s eying a potential showdown with her sister Venus in the semifinals. Venus, the tournament’s No. 18 seed, will be going against unseeded American Madison Keys on Wednesday. Keys has had a great run so far, taking out No. 4 seed Petra Kvitova in the third round.
While the matches are set for Wednesday local time, they actually start on Tuesday night in the United States. Television coverage will begin at 6 p.m. ET and run through 9 p.m. on the Tennis Channel. At that point, ESPN2 will air coverage from 9 p.m.-2 a.m., and then from 3:30-6 a.m. Wednesday morning.
