2015 U.S. OPEN TENNIS TOURNAMENT
ESPN, 7:00 p.m. ET
This has been quite an exciting, and exhausting, tournament so far – and yesterday’s games, particularly the tough loss by Andy Murray and, later, the intense win by Roger Federer that ended just before midnight, were long, grueling cappers to a wonderful tennis weekend at Flushing Meadows. And while today offers several matches, none is as anticipated as the quarterfinal match, at 7 p.m. ET, between Venus and Serena Williams (seen here at Wimbledon 2015). You know the stakes, and the hype, and the drama. Now watch one of the biggest sibling rivalries in sports history.
