Heartbreak for Niland at Flushing Meadows

Top seed Novak Djokovic barely had to break sweat to make it through the second round of the US Open as Irishman Conor Niland retired through illness while trailing 6-0 5-1 at the Arthur Ashe stadium.

Niland had required attention early in the second set after apparently being ill during the warm-up, and although he soldiered on for a short while, he bowed to the inevitable as Djokovic proved far too strong.
