Wimbledon finalist Jasmine Paolini was given the easiest of routes into the third round of the US Open after her opponent Karolina Pliskova retired after just three points.

A tough second-round draw against the 2016 runner-up was in prospect for Paolini but it lasted less than two minutes.

Pliskova appeared to twist her ankle midway through a rally and immediately walked to her chair and took her shoe and sock off.

Physios attended to the 32-year-old but the injury was too severe and she retired trailing 15-30 in the opening game.

Paolini was interviewed on court in a conversation which lasted longer than her match.
