US Open day one: Swiatek and Ruud advance, No 4 seed Rune out – as it happened

British qualifier Lily Miyazaki got her first ever grand slam win while 2017 winner Sloane Stephens was a big casualty

Azarenka is making short work of her match with Ferro and is 3-0 up in the second set, having won the first 6-1. She might well be the first winner back into the locker room of the early starters. Richard Gasquet meanwhile is two sets down, losing the second set to Maroszan 6-1.

The 2020 champion, Dominic Thiem, who made that odd start to the match with Bublik, and looked unwell, has taken the first set 6-3 and looks far less green around the gills.
