Rafael Nadal reached the semi finals of the French Open after fellow Spaniard Pablo Carreno Busta withdrew from their match with an abdominal injury while trailing 6-2 2-0.
Tournament favourite Nadal, 31, has won the French Open title on each of the nine previous occasions he has advanced past the quarter-finals.
He has now recorded 100 best-of-five-sets victories on clay from just 102 matches, with his only defeats coming at Roland Garros, to Robin Soderling in the fourth round in 2009 and Djokovic in the 2015 quarter-finals.
Rafael Nadal has also dropped just 22 games through five matches in Paris, bettering his previous low of 25 en route to the last four in 2008.
He broke Carreno Busta four times to take the first set, at the end of which the world number 21 needed a lengthy break to have treatment and bandaging applied to his stomach.
Carreno Busta lasted just two games of the second set before retiring to extend Nadal’s French Open record to an incredible 77 wins and just two losses.
