Roger Federer and Ernest Gulbis are still going at it hammer and tongs in the second set. Pistols drawn as we head into a second successive tie-break. Nothing to split them yet.

Over on Court Suzanne Lenglen, Carla Suarez Navarro has wrapped up the first set against Croatia's Ajla Tomljanovic. Eugenie Bouchard awaits for the winner of that one in the last eight.

John McEnerney: , external"Come on do your Spanish celeb research - Ana Boyer is Fernando Verdasco's latest girlfriend and her mum is Julio Inlesias's ex-wife. She not related to Julio."

See 13:50. I stand corrected. Apologies to all, especially Ms Boyer.

In a tenuous tribute to the on-site players hairdresser at the French Open, we are asking for your all-time top tennis hairdos.

Here is another to get your grey matter working.

Patriotic, stylish and with the option to delay play by loosening a braid and sending beads scattering across the playing surface, I bring you Venus Williams, 1997 edition.

Well, well. Two set points to the Fed and he has an easy smash to convert the second.

Anywhere in court will have him strolling back to his chair. Anywhere but there! He pattercakes his overhead straight to the corner of the court where Gulbis has taken shelter.

The Latvian gratefully pats away a winner into the acres of unguarded court and goes on to break himself. Back on serve.

Roger Federer feathers the accelerator to pull clear with a break of serve. Hold in the next one and he is two sets to the good.

John McEnerney: , external "Federer will hiccup & splutter his way to the semi-finals of the Slams with flashes of brilliance. Too many unforced errors in his game now."

Ernests Gulbis is still hanging tough in the second set. The Latvian is on serve with an hour and 18 minutes already on the meter and the second set only halfway done.

The French Open has plenty to recommend it. A rich history, all the attractions of Paris in the springtime, and perhaps the most bubbly of all Grand Slam crowds.

But quality of celebrity attendees is low. The best so far today is Ana Boyer.... You know, daughter of Spanish singer Julio Inglesias?

I don't think Tom Jones' sister would get a snap if she pitched up at SW19 later this month.

After Saturday's match hung over to Sunday, there will be no rest for Andy Murray on Monday.

He will have to take on Fernando Verdasco tomorrow for a place in the last eight. The Spanaird is also working through after his match against Richard Gasquet was interrupted by bad light last night.

Murray's record is more than solid against Verdasco - nine wins and just the one defeat. Their latest meeting was Murray's come-from-behind five-set win in the quarter-finals of Wimbledon last year.

Following in Andy Murray's slipstream on Court Suzanne Lenglen is the match between Spanish 14th seed Carla Suarez Navarro and world number 72 Ajla Tomljanovic.

Tomljanovic, who failed to make it through qualifying in four previous visits to Roland Garros, is into the last 16 of a Grand Slam for the first time.

She has already accounted for third seed Agnieszka Radwanska and 32nd seed Elena Vesnina.

Roger Federer claws his way out of trouble, rolling Ernests Gulbis over in the tie-break with a silky smooth backhand. Fizzing with top-spin, his pass lands well in court to wrap up the opener.

He has been pushed hard by Ernests Gulbis so far today though and this sleeker, leaner more concentrated version of the Latvian may not be shaken off as easily as in the past.

Tom Swain:, external Having paid very little attention to Roland Garros thus far, I am completely made up that Andy Murray has just won.

LawrenceGarnerAllen:, external Job done for Andy, but by no means any easier from here on in. Verdasco will be a difficult test for Murray on the clay.

"I need to try to recover as best I can," said the Scot. "Yesterday I was cramping so maybe it was a good thing the match was stopped.

"The muscles were a bit sore today but, hopefully, if I do the right recovery I will be OK and fight as hard as I can to try to get through to the next round."

A quick scoot over to Philippe Chatrier and what do we have here?

"Me? Roger Federer, 17-time Grand Slam champion, in a tight first-set tiebreak with Latvian playboy Ernests Gulbis?"

Yep, that's right. We are on serve at 3-3 in the shoot out.

"Andy Murray seized his moment. He hit the backhand across court for the winner. A drama that need not have been written as Murray let a golden opportunity slip last night.

"But you have to hand it to him as he has got the job done. There is no smile on his face, just relief."

"Last night was tough as I did a lot of running," said Murray. "Philip Kohlschreiber played some great tennis end of fourth and fifth sets yesterday.

"Considering the circumstances today I thought we played some very good tennis.

"I didn't sleep much last night and woke up a few times. I slept about five hours.

"I was very nervous. I just tried to do my usual preparations but it is not easy coming back 7-7."

Andy Murray drops to a crouch, bellowing with relief more than joy. There is not much of a smile on his face as he advances to the net, he probably feels that he should have been pressing the post-match flesh and into the fourth round yesterday.

Andy Murray sets his feet behind a backhand and whips away a winner for 0-15, Kohlschreiber is caught out by a groundstroke of impeccable depth and then dumps a forehand long.

It all adds up to 15-40 and two match points. First serve missed. And Murray buries the second with a ripped backhand winner.

BBC Sport's Gigi Salmon: "Things are warming up nicely. Gulbis broke but gave it away with a very sloppy service game Both are struggling on serve."
