Novak Djokovic on the brink of shock exit
Defending Wimbledon champion Novak Djokovic is staring down the barrel of defeat trailing by two sets against journeyman Sam Querrey.
Rain came to the world number one's aid last night when he trailed the American 7-6 (8/6) 6-1.
Djokovic was out of sorts in his third round match and will need all his renowned powers of recovery to stay in the tournament when his match resumes today.
In another shock Juan Martin del Potro rolled back the years to his 2009 US Open final triumph, yesterday beating fourth seed Stan Wawrinka 3-6 6-3 7-6 (7/2) 6-3 in the second round.
Roger Federer dominated against British hopeful Dan Evans, easing to a 6-4 6-2 6-2 win.
Andy Murray is back in action today when he takes on Australia's John Millman.
There will be action on the middle Sunday for the first time since 2004 after the disruption caused by rain delays.
