World number two Coco Gauff beat Lucia Bronzetti 6-2 6-4 to book her place in the quarter-finals of the Cincinnati Open.
The two players had progressed to the last 16 in contrasting ways, with Gauff having won her only match in straight sets before a walkover against Dayana Yastremska in last round.
Bronzetti, on the other hand, had come through in three sets in her previous three rounds and the world number 61 quickly found herself 3-0 down.
Gauff was broken in the fifth game but it proved a brief blip as she went on to win the opening set in 33 minutes.
