At 15-15 an intriguing baseline slug-fest ensues... Arguello the aggressor, racing towards the tape and getting the better of Murray with a brilliant volley. Balletic and brutal.

At 30-30, Murray attempts to outfox his opponent at the net but fails to do so, clumsily netting. The third seed hanging on, though, forcing the game to deuce and an unforced error from Arguello - his 16th of the match - is a break point with a cherry on top for the Scot. Murray doesn't mess this chance up. Well, he doesn't have a chance to do much of anything as the Argentine hits loose and wild once more.

"Kim Sears is courtside for the first time since becoming Mrs Murray last month, and her husband has not lost since they tied the knot on April 11th.

"Perhaps of more significance are the men she is sitting alongside - physio Mark Bender and trainer Matt Little, who have brought their man to Paris in the best shape he has felt since back surgery in 2013.

"A few wobbles from the third seed in this first set but no danger yet that his wife is about to witness a major shock."

Murray, with the court at his mercy, slaps a forehand into the tape which gives Arguello some hope at 30-15. The Scot embarks on a brief monologue as he wipes his sweaty forehead. There's nothing wrong with talking to yourself, so they say, and sometimes a good talking to works, as Murray proves as he breaks free of his rival and winds up the game with a classy ace.

Is the wind troubling Murray? Possibly. The Briton balloons a backhand long for 15-30 and is then outfoxed by a cannily disguised drop-shot from the baseline. The Argentine serves out with little fuss and we're level after 27 minutes.

Meanwhile, we have a third British player on court at Roland Garros. British women's number two Jo Konta is about to take on world number 86 Denisa Allertova of the Czech Republic.

The world number 144, who last qualified for a Grand Slam at the US Open in 2012, came through qualifying to take her place in the first round.

Heather Watson is one game away from a place in round two. She has just broken France's Mathilde Johansson and held her own serve to lead 6-5 in the second set. The Brit won the first set 6-4.

The Murray forehand leaking points - Arguello 0-30 to the good without breaking sweat. A lengthy baseline battle ensues... Murray shuffles towards a tramline, targets the Argentine's backhand but the Scot's forehand falters once more. THREE BREAK POINTS Arguello. He lets one slip by but on his second bite he causes some damage. Murray yet to get to grips with this match.

Andy Murray is liking the clay this year and the clay is liking him. The Scot has won his first two titles on the surface and is on a 10-match winning streak. Is there anyone else in better form? Only world number one Novak Djokovic has won multiple titles on the dirt in 2015.

It's currently a little blustery on Chatrier, which perhaps explains why both players are making a number of errors. A limp backhand into the net from Murray and Arguello is 40-0 up, but it doesn't take much for the Argentine's shoulders to slump.

An ill-judged drop-shot helps Murray to 40-30 but the Scot fails to negotiate the barrier on the next point, opportunity missed, and it's Arguello clenching his fist and eyeballing his team in the crowd.

Two easy points for the Briton from the back of the court and Arguello's resistance seems to have crumbled. His forehand is malfunctioning, the Argentine swinging like a faulty windmill.

Two more errors from the 22-year-old allows Murray to trot back to his chair for the changeover with another game in his back pocket.

For those of you who haven't done your homework on Facundo Arguello, the world number 137, you are forgiven, it is a Bank Holiday after all.

What might be useful to know is that Murray has not lost to a player ranked as low as the 22-year-old since his 2011 Indian Wells loss to Donald Young, then ranked 143 in the world. But don't expect this sort of detailed analysis from us all the time - it's not as if it's our job to provide information and statistics.

Oh. Hang on, apparently it is, so let me tell you Murray squanders one break point but is gifted another as Arguello swings wild and wide with a forehand. What will Murray do? He doesn't have to do anything. Arguello goes into the tramlines and the Briton has an early break.

Murray opens up with a punchy first serve which leaves his opponent floundering. Promising. An iffy drop shot on the next point, though, from the Briton and we're level at 15-15. Not so promising. The unfancied Argentine wins another point and receives warm applause from the Parisian crowd.

There's nothing to worry about, though, is there? Nah. Or non, as we should say. A cute drop shot from the Scot, followed by a crunching serve, and the former Wimbledon champion is a point away from seeing off his rival. Easy. Oh...

Arguello drags the game to deuce and is gifted a break point thanks to a double fault from the British number one. Break point saved but Murray can't inflict the killer blow. Seven minutes tick by... An ace from Murray to advantage and, eventually, the Scot comes out on top of a lengthy rally to win the opening game.

Piers Newbery
BBC Sport at Roland Garros

"It's a cool, breezy afternoon on Court Philippe Chatrier as Andy Murray prepares to begin his French Open campaign. His form has been such that it doesn't seem completely outlandish to call it a "title bid", although the man himself admits the likes of Djokjovic, Nadal and Ferrer remain above him in the clay-court pecking order.

"Murray has cut a relaxed figure around Roland Garros for the last few days and enjoys a few jokes with trainer Matt Little and coach Amelie Mauresmo as he waits to come on court. The last time he played here, Murray was taken apart by a rampant Nadal. Now is the time to start erasing that unpleasant memory."

Andy Murray arrived in the French capital having enjoyed his most successful year on the surface, a run which included picking up titles in Munich and Madrid.

But what chance does the world number three have of winning the title at Roland Garros?

"What with Nadal's form and Andy's recent results, you'd have to say this is the best chance Andy has ever had to win the French Open," says Mark Petchey, Murray's former coach.

"His second serve is as strong as we've ever seen it, his backhand down the line has been great and perhaps most importantly, he feels comfortable physically now as well."

"Deux minutes!" bellows the umpire which means a couple of minutes until the warm-up is over and Andy Murray gets his 2015 French Open campaign up and running.

There are five Britons in action at Roland Garros today. Five! Aljaz Bedene has already been beaten, however, with the British number two losing 6-3 6-4 6-7 (6-8) 6-3 to Austria's Dominic Thiem. You can read about that match thanks to our very own Piers Newbery who has travelled all the way to Paris.

So far, the day can be summed up a little like this:

Hello! Welcome to live text coverage of Andy Murray's ring-a-ding-dong with Argentine Facundo Arguello. It should be a relatively comfortable first-round outing for the Scot who is, of course, unbeaten on the court since he married Kim Sears in April.

It's probably best to inform you nice and early that there's live BBC Radio 5 live coverage of this match available somewhere at the top of this page.

You tie the knot to the woman of your dreams and life becomes one great love song. It's as if Michael Buble is on your shoulder wherever you go; singing in your ear as you go from tournament to tournament, winning and winning and winning.

A drop shot there, a deft volley here, everything seems so easy, even on a surface you struggled on in the past. Even beating the King of Clay feels like child's play. But how long will this feeling last? Will the honeymoon on clay ever end?
