Andy Murray must come back on Sunday to try to finish off Philipp Kohlschreiber after play was suspended for darkness at 7-7 in the fifth set of their third-round match at Roland Garros.

The pair followed a crazy five-set match between Gael Monfils and Fabio Fognini onto Court Suzanne Lenglen and produced just as many twists and turns.

After three hours and 27 minutes they were tied at 3-6 6-3 6-4 4-6 7-7, with Murray having fought back from a set down to lead only to make a mess of the fourth when the match seemed in his grasp.

It is the first time the Wimbledon champion has been extended beyond 6-6 in a non tie-break set in his career and, given he seemed to be the one struggling physically, the break may prove to be no bad thing.

Rafael Nadal is through to the fourth round without dropping a set after defeating Leonardo Mayer on Court Philippe Chatrier.

The eight-time champion overcame a few sticky moments in the second set to see off the Argentinian 6-2 7-5 6-2 in two hours and 17 minutes.

Nadal had been hugely impressive in defeating rising star Dominic Thiem in round two and he started in the same vein against Mayer.

It was the first warm and sunny day of the tournament, which helped Nadal’s extreme spin fizz off the clay.

He won five of the first six games and looked on his way to a very straightforward victory when he broke the Mayer serve again early in the second set. But Mayer began to put a lot more pressure on the Spaniard and got his reward when he broke back for 4-4.

In the next game he was two points away from taking the set but Nadal held on and then broke the Mayer serve once more with a precision lob, the Argentinian imploring the ball to go long then shaking his head when it landed on the line.

Nadal let a break slip away at the start of the third set as well but finally broke Mayer’s resistance with a run of five straight games to win the match.

Next the world number one will face Serbian Dusan Lajovic, who is through to the last 16 on his first appearance at Roland Garros.

The 23-year-old, who defeated Jack Sock in straight sets, said: “I can’t be more happy than this. To play Rafa on Chatrier is one of the biggest dreams and biggest challenges.”

Fifth seed David Ferrer is yet to drop a set this tournament, with 32nd seed Andreas Seppi his latest victim in a 6-2 7-6 (7/3) 6-3 victory.

Last year’s runner-up has now made at least the fourth round in 16 consecutive grand slams and will look to make it 10 straight quarter-finals when he takes on Kevin Anderson.

The 6ft 8in South African was involved in a battle of the giants against 6ft 11in Ivo Karlovic but the Croatian had to pull out after a set because of a back problem.

The much-anticipated clash between Gael Monfils and Fabio Fognini was a predictably wacky five-set affair.

With two of the most flamboyant players meeting, it was a match where anything was possible, and it was Monfils who eventually came out on top 5-7 6-2 6-4 0-6 6-2.

The pair made 137 unforced errors between them and Monfils recovered to win despite appearing barely able to move in the fourth set because of cramp.

The Italian, meanwhile, was given a point penalty in the third game of the deciding set for throwing his racquet having previously received a warning for swearing.

The crowd on Court Suzanne Lenglen lapped up every crazy moment and mass delirium ensued when Fognini missed a forehand to bring the match to an end after three hours and 24 minutes.

Monfils is through to the fourth round at a grand slam for the first time since reaching the quarter-finals at Roland Garros three years ago.
