Kudermetova sees off Gauff to set up Swiatek semi in Doha

Iga Swiatek will play Veronika Kudermetova in the Qatar Open semi-finals after the Russian defeated Coco Gauff in the last eight.

World number one Swiatek was already assured of her semi-final place heading into Thursday as Belinda Bencic's withdrawal had granted her a walkover.

She could watch on then as Kudermetova upset fourth seed Gauff 6-3 3-6 6-1 in Doha.

Swiatek has won each of her previous two matches against Kudermetova in straight sets, but the world number 11 will be on a high after her first top-10 win of the season.

It will be the 25-year-old's second semi of the season, although she withdrew from her Adelaide 2 match-up against Bencic.

While Gauff is out, there remains American representation as her doubles partner Jessica Pegula made light work of Beatriz Haddad Maia 6-3 6-2.

Pegula, the second seed, will face Greece's Maria Sakkari, who overcame third favourite Carolina Garcia 6-2 6-7 (5-7) 7-6 (7-5) in a battling encounter.
