MELBOURNE, Australia – Coco Gauff's latest history-making Grand Slam run at age 15 ended with a 6-7 (5), 6-3, 6-0 loss in the Australian Open's fourth round to Sofia Kenin on Sunday.
Like Gauff, Kenin is a young--although, at 21, not quite as young--American and she reached her first major quarterfinal with the victory.
In her previous match, Gauff beat Naomi Osaka to become the youngest player in the professional era to defeat the reigning women's champion at the Australian Open.
But Gauff did not play as well this time, winding up with 48 unforced errors, more than twice as many as Kenin's 22.
