Jo Konta has been broken in the third set by Denise Allertova. The Briton trails 3-1 in the decider, with the Czech surely now favourite to proceed.

For those of you who missed the story, French player Virginie Razzano stunned the crowd on the Suzanne Lenglen earlier by attempting to serve out for victory with an underarm serve.

The wildcard entry missed with the underarm second serve to concede a double fault against Paraguayan qualifier Veronica Cepede Royg.

But she still managed to complete a 2-6 6-4 6-2 victory, saying: "I wasn't feeling that great today. I'm sorry, I spooned the ball over. That's the baggage that I carry."

Over on Court Seven, Kyle Edmund is refusing to wilt against home favourite Stephane Robert. The Briton was 2-0 down in the fourth set, but the 20-year-old has battled back and the set is now on serve. Perhaps this match won't need a fifth set after all.

Slone Stephens has beaten Venus Williams 7-6 (7-5) 6-1 which means the young American will face Britain's Heather Watson in the second round. How exciting.

"Jo Konta is putting in some effort out on Court Five, levelling at 6-7 6-4 against the higher-ranked Denisa Allertova. After eight set points went begging in the first, although only maybe two of them were real chances, the British number two sees a ninth slip by in the second set. She keeps a good length on her groundstrokes though, and Allertova offers up yet another set point - and this time the Czech double faults! Cue a huge scream from Konta, probably as much relief as delight."

What's happened to Henri Leconte? We're not too sure but the Frenchman needed some ice on his ankle in the treatment room. "I didn't know that commentating is so DANGEROUS," tweets Sergiy Stakhovsky.

How is Jo Konta getting on? The second set is with serve at 5-4, although the Briton has just squandered a break point against Denisa Allertova. Konta has won just one of seven break point opportunities in her match which could be telling come the end of the match.

How do tennis players prepare for a Grand Slam? They put on a pair of blue jeans, grab and acoustic guitar and pretend to be Bob Dylan. "Getting ready for tomorrow in a special way," tweets Wimbledon champion Petra Kvitova.

Hello there! There was a moment in the eighth game of the third set when some of the crowd were on their feet, revelling in Stephane Robert's shot-making. But Kyle Edmund has gravel in his guts and saw off the danger to break and he's now served out the set. The Briton a set away from the second round.

Kyle Edmund was 4-2 up in the third set against Stephane Robert, but the Frenchman has just broken the 20-year-old Briton to put the third set back on serve.

British number ones Andy Murray and Heather Watson are safely through, all eyes are now on whether Jo Konta and Kyle Edmund can join them. "I don't think I'm on a par with Andy yet," says Watson. "But I think it's great, especially having so many Brits in the draw. It's just brilliant for British tennis. Hopefully it just keeps getting better and there are more Brits in the draw and we can help push each other along."

Andy Murray is now unbeaten in 11 games on clay and is through to the second round but who will he need to beat to win this thing? Well, we've come up with a potential route to the final. You're welcome.

Round two: Vasek Pospisil (Canada, ranking 51)

Round three: Nick Kyrgios (Australia, seeding 29)

Round four: John Isner (US, seeding 16)

Quarter-final: David Ferrer (Spain, seeding 7)

Semi-final: Novak Djokovic (Serbia, seeding 1) / Rafael Nadal (Spain, seeding 6)

Final: Roger Federer (Switzerland, seeding 2)

Asked whether it was more difficult to get Kim Sears to marry him than win two titles on clay, Murray smiles. "She'd put up with me for nine-and-a-half years so it was probably about time I proposed and I'm glad she said yes. My tennis since we got married has been good and I hope I can keep that up."

"I was nervous today," says Andy Murray. "Always the first round of the major competitions are tough and it was quite windy and difficult conditions at the start. I was a little bit nervous at the start but I like that, it shows that you care and want to do well."

Three match points for Murray and the crowd are whistling their approval. Arguello pounces on a tame Murray overhead but he only delays the inevitable. The Argentine balloons a forehand and Murray is through to the second round.

At 0-15, Arguello is controlling Murray from the baseline, sending him to the wings and then dragging him towards the net with a peachy drop-shot. Not even a man of Murray's powers can get to that one so to 15-15 we go. Arguello fighting once more, easing 40-15 ahead, but Murray hauls him to deuce and the Argentine must prepare for another battle. The underdog has nothing left to give, it seems, gifting Murray a break point and Murray does not need a second invitation.

Rat-a-tat-tat. Murray, calm and ruthless, rattles off thee points quickly, cantering to a 40-0 lead - and within a few seconds he's secured another game to take a firm step towards the second round.

What was that about a Murray procession? Arguello battles to hold, forming a fist and flexing his right bicep as he completes a straight-forward hold. The Argentine might have arrived a little too late for this particular party, though.
