RIYADH (Reuters) -World number one Aryna Sabalenka earned a 6-4 2-6 6-3 win over Jessica Pegula, while defending champion Coco Gauff put on a clinical performance to beat Jasmine Paolini 6-3 6-2 and eliminate the Italian in Riyadh on Tuesday.

Sabalenka, who has won two matches in a row in the round-robin Group Steffi Graf, is on the verge of qualifying for the semi-finals. Gauff and Pegula, who have one win each, also remain in contention for the last four.
