Coco Gauff produced an impressive comeback win to reach the Australian Open quarterfinals on Sunday, eventually downing Belinda Bencic 5-7 6-2 6-1.

MELBOURNE, Australia -- Coco Gauff 's retooled forehand and serve abandoned her in the worst way and at the worst time at the Australian Open. The unforced errors just kept accumulating, and so did the double-faults and break points, often followed by a palm placed over her eyes or a slap to a thigh.

Coco Gauff vowed to ignore the “internet coaches” after suffering a shock Australian Open defeat to Paula Badosa. And the American insisted: “I'm not crushed”. The world No.3 arrived at the first Major of the season in hot form after winning the season-ending WTA Finals and then going unbeaten at the United Cup.
