Sonay Kartal upsets Mirra Andreeva to record biggest scalp of her career

Kartal, 23, edged the first set by taking her sole break point opportunity against the fourth seed.

Andreeva responded emphatically in the second set, breaking twice as Kartal struggled with a 60% first serve percentage.

But Kartal, the world number 81, showed her resilience in the third set as Andreeva failed to build on her momentum.

After failing to take match point, Kartal took her second opportunity as Andreeva fired wide.

Kartal has only dropped one set across four rounds on her way to the last eight in Beijing, where she will face world number 27 Linda Noskova for a place in the semi-finals.
