Coco Gauff sailed into the last 16 of the US Open on Saturday with a routine win over Magdalena Frech as men's reigning champion Jannik Sinner prepared to ramp up his title bid.
Gauff swept past Polish 28th seed Frech 6-3, 6-1 in her most polished display of the tournament to boost her hopes of collecting a second US Open title and third Grand Slam overall.
