British number one Emma Raducanu is out of the Australian Open after losing in straight sets to Coco Gauff in a gripping second-round match.
Raducanu, ranked 77th in the world, acquitted herself very well against the American seventh seed but a lack of matches told in a 6-3 7-6 (7-4) defeat.
The 20-year-old had battled an ankle injury before the Melbourne major.
Defeat means Raducanu has not reached the third round of a Grand Slam since her stunning 2021 US Open win.
Teenager Gauff, who famously reached the Wimbledon last 16 as a 15-year-old in 2019, is among the favourites to win the title at Melbourne Park.
