Rafael Nadal continued his superb form with a dominant 6-1 6-2 6-2 win over Roberto Bautista Agut to move easily into the French Open quarter-finals.
The Spaniard, 31, is looking to become the first man to win 10 titles at a single Grand Slam event.
His victory was not quite as simple as Friday’s incredible 6-0 6-1 6-0 defeat of Nikoloz Basilashvili but fourth seed Nadal has not dropped a set yet.
Carreno Busta, 25, reached his first Grand Slam quarter-final with a 4-6 7-6 (7-2) 6-7 (6-8) 6-4 8-6 win over Canadian fifth seed Milos Raonic.
Carreno Busta, seeded 20th, failed to convert six match points in the deciding set before eventually grinding down last year’s Wimbledon runner-up.
And a first career win against a top-10 ranked opponent will be rewarded with a meeting against nine-time champion Nadal.
Margaret Court is the only player to have won 10 or more titles at one Grand Slam event, winning the Australian Open on 11 occasions between 1960 and 1973.
Nadal now has a 76-2 win-loss record at Roland Garros with his only defeats coming against Robin Soderling in the fourth round in 2009 and Novak Djokovic in the 2015 quarter-finals.
It is the 11th time he has reached the quarter-finals at the French Open – a record shared with Roger Federer.
World number two Djokovic matched that record when he defeated Albert Ramos-Vinolas 7-6, (7-5),6-1,6-3 yesterday.
