No. 3 Andy Murray vs. No. 6 Tomas Berdych, 11 a.m.
No. 2 Novak Djokovic vs. No. 4 David Ferrer,
following Murray-Berdych match
TV: CBS3 Web:www.usopen.org.
What to expect: Roger Federer is gone. Rafael Nadal never showed up. Of the four men left at Flushing Meadows, only Djokovic has won it all at any of the sport's four majors. That makes the Serb, who has five Grand Slam trophies and is defending champion at Flushing Meadows, the favorite heading into Saturday's semfinal. Despite being the defending champion, he was relegated to second billing - or lower - by Andy Roddick's retirement, rain delays and other factors. He played in the afternoon, not evening. His matches were in 10,000-seat Armstrong Stadium, not 23,000-seat Arthur Ashe. But on Thursday, in prime time in Ashe, Djokovic gave everyone an unmistakable view of what they might have missed. His straight-sets win over 2009 champion Juan Martin del Potro was Djokovic tennis at its finest. Djokovic still hasn't lost a set in this tournament. . . . Murray has reached four Grand Slam finals but is still in search of his first win, and sixth-seeded Berdych, who lost in the first round at both Wimbledon and the Olympics, was a Wimbledon finalist in 2010. Berdych has a 4-2 lifetime record against Britain's Murray, who carries his entire nation's hopes with him every time he enters a major.
