Coco Gauff dismantles Iva Jovic to reach quarter-finals in confident US Open run

• Gauff defeats Jovic 6-1, 6-4 in 80 minutes

• American has yet to drop a set in New York

• Andreeva awaits in anticipated quarter-final

Coco Gauff continued her serene march through the US Open women's draw with her most complete performance yet on Monday night, seeing off fellow American Iva Jovic 6-1, 6-4 to reach the last eight in New York for the first time since winning it all in her grand slam breakthrough three years ago.

The fourth-seeded Gauff overwhelmed Jovic with the depth of her returns and an assured blend of aggression and defense, finishing with twice as many winners (18 to nine) and half as many unforced errors (15 to 30). The 1hr 20min clinic was the latest statement in a late-summer win streak that has transformed her from a player searching for answers this time last year into perhaps the most dangerous woman remaining in the field.
