Gauff dumped out of Qatar Open by Siniakova in second round
Coco Gauff crashed to a surprise second-round exit from the Qatar Open on Tuesday with a straight-sets defeat by Czech Katerina Siniakova.
The world No. 3's 6-2, 6-4 loss in her opening match in Doha marked the first time she has failed to reach the quarterfinals of a tournament since Wimbledon last year.
US Open champion Gauff dropped serve six times in an error-strewn display, blowing a 4-0 lead in the second set.
Siniakova will next face Danielle Collins in the last 16.
Earlier on Tuesday, Australian Open runner-up Zheng Qinwen battled to victory in her first match since losing the Melbourne final to Aryna Sabalenka, beating Magda Linette 6-2, 2-6, 6-3.
