Djokovic and Murray set for US Open quarter-final clash
Federer gets easier-looking draw

Novak Djokovic and Andy Murray were put on a quarter-final collision course for the US Open Thursday while Roger Federer’s hopes of an 18th grand slam title were buoyed by a kinder draw.
World number one Djokovic, who won the title at Flushing Meadows in 2011, is the top seed and will be trying to reach the final for a fifth straight year.
Djokovic opens his campaign against Argentina’s Diego Schwartzman. He could come up against 13th-seeded John Isner in the fourth round, but the big-serving American arrives in New York nursing an ankle injury that forced him out of the tournament in Winston-Salem on Thursday.
Eighth-seeded Murray, the 2012 US Open winner who hasn’t won a title since his emotional 2013 Wimbledon triumph, opens against Robin Haase of the Netherlands and could face a dangerous fourth-round clash with French ninth seed Jo-Wilfried Tsonga.
Federer has a lighter-looking path in the bottom half of the draw, with seventh-seeded Bulgarian Grigor Dimitrov his scheduled quarter-final foe.
