Ostapenko knocks out Gauff to reach Australian Open quarters

MELBOURNE : Jelena Ostapenko stunned Coco Gauff 7-5 6-3 to reach the quarter-finals of the Australian Open on Sunday after putting on a power-hitting clinic.

Latvian Ostapenko has struggled to reach the heights of her French Open-winning days but the 17th seed simply overpowered the American at Margaret Court Arena.

Ostapenko was ruthless in the finish, unleashing a thumping forehand down the line to bring up match point, then clipping the line with a crosscourt forehand winner to give Gauff no chance.

The 17th seed will meet Elena Rybakina, who shocked top seed Iga Swiatek, for a place in the semi-final.
