Gauff lost to Sakkari in last year's semifinal at the BNP Paribas Open, but on Monday it was Gauff playing her best during the biggest moments

Coco Gauff overcame late nerves to beat Maria Sakkari 7-6 (1), 6-2 and reach the round of 16 at Indian Wells on Monday, as her fellow American Madison Keys held off Elise Mertens 6-2, 6-7 (8), 6-4.

Gauff, who escaped her opening-round match in three sets despite having 21 double-faults, was back to her best as she sealed a 7-6 (7-1) 6-2 win in one hour and 35 minutes
