The longest rally of the match - 13 strokes, for those counting - goes Haddad Maia's way, and she's handed some more fortune when Robson sends a forehand wide from up at the net.

It's difficult not to feel sorry for Robson. She looks down on confidence - she's been battling first with wrist problems and then with a shin injury, and she's not been moving with much fluency here.

World number 10 Jo-Wilfried Tsonga is a set up against British wildcard Cameron Norrie.

The second set remains evenly poised, though. You can follow their match on court two right here.

Joel Newnham: Robson's panicking on Court 18.

Philip Murphy: Not a good start for the British tennis players.

Rufus: Wimbledon - the time of year when all of my capable devices are playing a different match simultaneously.

But that's better from Robson as she holds her service comfortably, sealing the game with a thumping forehand.

Britain's Fed Cup captain Anne Keothavong is sitting in front of me in the tiny area for media and coaches on Court 18, and has been giving Laura Robson steady encouragement throughout this match, along with Robson's coach, Magnus Norman.

Robson has been looking towards them quite a lot - she is visibly frustrated by the number of unforced errors she has been making, that have left her a lot of work to do.

A bobble off the net falls in Laura Robson's favour this time, and she gets a pleasing round of applause from the crowd as Haddad Maia stretches and nets.

The Brazilian's serve gets her out of trouble again, though - Robson just can't pick it up when it comes down wide. An ace, fizzing cross-court, and a delicate backhand at the net and Haddad Maia holds

Nick Kyrgios looks like a man trapped in quicksand, rather than on the soft grass of Wimbledon.

Can he find anything at all to ignite the undoubted fuel inside him?

Haddad Maia races to a break point. Robson takes a deep breath, throws up the ball and hammers down a serve. The return is short, Robson's eyes light up, she darts in - and skews the ball into the net! That'll hurt. An early break to Haddad Maia.

The unforced errors tells a story - it hasn't been a smooth start for either Beatriz Haddad Maia or Laura Robson. It's the Brazilian that leads, though, thanks to some fine, fiery serving.

The lanky Pole Jerzy Janowicz has consolidated that break and claim the first set against Denis Shapovalov.

The Canadian did take him to deuce in that last game though and will hope to get after Janowicz's serve more in the second set.

Laura Robson is just trying to find her feet in this contest. They both look quite uncomfortable at times but Haddad Maia is someone who is on the up in the rankings. She's got a lot of confidence and has won a lot of matches this year, but is very inexperienced on grass.

Haddad Maia breezes to her first set point with a low forehand winner but Robson forces it to deuce as she skips forward and hammers n a forehand. Plenty of gusto behind that one.

Advantage Haddad Maia with a corker of a shot down the line, and she clinches the set with a big serve that Robson can only watch bounce past her. Can she come back from a first set loss?

Love him or don't really like him (we don't do hate or loathing here), Nick Kyrgios is box office.

Court three, one of the smaller show courts, is jam packed.

The Fanatics - that group of vocal, green and gold-wearing Aussies - are behind one baseline, plenty of other accents from Down Unser audible everywhere else.

But their man is lacking a spring in his step. Kyrgios pulled out of Queen's with a hip injury and is wearing some medical stockings to presumably protect his lower limbs. Otherwise it would be a major fashion statement

He double faults to hand over the first break at 5-3, France's Pierre-Hugues Herbert serving out the set to love.

That's better from Robson - she keeps her composure, sending down two serves into opposite corners of the court.

She takes a long slurp of one of those weird juice things as she glances up to the crowd. Haddad Maia will serve for the first set.

Andy Murray is not the only player struggling with hip issues, Nick Kyrgios said at the weekend he was only "65%" fit after aggravating a long-standing problem with a heavy fall, and subsequent retirement, at Queen's Club. Pierre-Hugues Herbert is not the best opponent to have across the net when you're feeling a bit sore - the Frenchman is one of the best doubles players in the world and loves attacking on a grass court.

Kyrgios and Murray are in line to meet in the fourth round, but that looks a long way off right now.

We have a break of serve on court two...and it's gone to Jo-Wilfried Tsonga. The 12th seed leads Britain's Cameron Norrie 5-3 in the first set.

Watch live here.

Ugh, that double fault has completely sucked any energy out of Kyrgios.

There is very, very little resistance from the Australian as Herbert races into a 40-0 lead.

And a lovely, deft drop shot from the Frenchman to take the game and the set.

Kyrgios looks empty. Can he muster anything here?

Another big serve from Haddad Maia and Robson doesn't read it properly again. Down the line is the reply from Robson, and Haddad Maia simply hammers a fine, spinning forehand in response.

The Brazilian is a game away from the opening set.

Nick Kyrgios looks like he's prepared to try and win this match with his serve alone.

He might just do it too, belting nothing but fire from the service line.

The problem is Pierre-Hugues Herbert has started to fire it back. And when the ball is in play, Kyrgios is clearly not moving well.

Those problems then creep into his much-vaunted serve as the Australian double faults and Herbert will serve for the set...

Plenty of shouts of "Come on Laura!" from the home support on Court 18 for Laura Robson, and it looks like she will need their help to get through this one.

Robson is having a lot of joy with her big forehand, but still can't quite get to grips with Beatriz Haddad Maia's serve, and is having to fight hard to avoid another break on her own.
