Coco Gauff knocked out of Australian Open

Teenage phenomenon Coco Gauff missed out on her first Grand Slam quarter-final as fellow American Sofia Kenin fought back to win in the Australian Open fourth round.

Gauff, 15, lost 6-7 (5-7) 6-3 6-0 to the 14th seed in Melbourne.

She showed all her undoubted quality in the first set, but tired in the third as Kenin wore her down.

Kenin will next face Tunisia’s Ons Jabeur, who beat Serena Williams’ conqueror Wang Qiang in straight sets.

After a warm embrace at the net, Kenin and Gauff broke out in tears following an intense battle on Melbourne Arena.
