Britain's Jack Draper matched his best Grand Slam performance with an efficient win over Botic van de Zandschulp to reach the fourth round of the US Open.

The British number one's side of the draw in New York had been blown open by Carlos Alcaraz's defeat by Dutchman Van de Zandschulp in the previous round and Draper made the most of the opportunity with a 6-3 6-4 6-2 victory.

In muggy conditions at Flushing Meadows, where Draper repeatedly used ice packs on his neck and blasted himself with an air conditioning unit at changeovers, the Briton was cool and clinical against his weary-looking and error-prone opponent.

Draper, the 25th seed who has yet to drop a set here, will face Czech world number 39 Tomas Machac for a place in the quarter-finals.

Fellow Briton Dan Evans will seek to join him in the last 16 later on day six of the final Grand Slam tournament of the year when he takes on Australian 10th seed Alex de Minaur (00:00 BST Sunday)
