Rafael Nadal beat Novak Djokovic in a four-set thriller on Wednesday to stay on course for a 14th French Open title and a record-extending 22nd Grand Slam triumph. Nadal overcame the World No.1 6-2, 4-6, 6-2, 7-6 (7/4) in a gruelling quarter-final clash that lasted over four hours at Court Philippe Chatrier to avenge his defeat to Djokovic in the Roland Garros semi-final last year. Memories of that match must have come back to him when Djokovic came back from two breaks down to win four games on the trot and eventually take the second set after Nadal led 0-3 at one point. However, the veteran Spaniard came back strong to win the next two sets and keep up his incredible record in the tournament.
