sport news Serena Williams equals record against sister Venus at US Open

Going head-to-head with sister Venus for the 30th time brought out the best in Serena Williams as she hit top form at the US Open.

Just before the match, Serena shared a video on Instagram from exactly a year ago when she was in labour preparing to give birth to daughter Olympia.

There will be further tests to come that will show whether she is totally back to her best, but there was little to fault as she raced to a 6-1 6-2 victory in just an hour and 11 minutes, equalling the most one-sided match in their long history.
