1977 Wimbledon champion on BBC Sport

"I think any of these players might be excused for being a little bit fatigued at this stage, not for the heat, but the nervous tension, especially for the British girl. It takes its toll."

"One of our Colombian friends shows her English language skills with a strategically-planned 'Come on Mariana' just ahead of that pivotal deuce on Broady's serve.

"The British fans respond in almost unison with several Broady-boosting ripostes.

"But it doesn't help the home favourite. Duque-Marino nabs the first break of the second set at the fifth opportunity.

"Broady's 22 unforced errors to her opponent's 12 pretty much tell the story..."

Grigor Dimitrov has signed for the second set out on Court One against Federico Delbonis.

Meanwhile Sloane Stephens whips a forehand winner down the line to keep the first set of her encounter with Barbora Strycova on serve at 4-3.

Liam Broady on Instagram following his five-set win today:

"What an atmosphere. Mats Wilander told me it's the loudest he's ever heard court 18 so thank you to everyone for the support. Goffin on Wednesday and hoping for the same support again! #unforgettable #goosebumps #MuchAppreciated."

If someone hasn't already dubbed this Five-Set Monday, then I shall. Out on 10, France's Pierre-Hugues Herbert (pronounced 'Air Bear') has finally seen off the challenge of South Korea's Hyeon Chung in a old-fashioned ding-donger. Chapeau, Air Bear.

"One of the greatest things about sport is seeing the wave of emotions of those involved - whether it is unbridled joy or total despair.

"At the moment, Naomi Broady's actions seem to indicate the latter.

"After most of the points in this second set, the 25-year-old British number three turns to the green canvas behind, mutters something to herself and stares at/slaps her strings.

"An emotional release worked a treat for brother Liam earlier - he received a violation for a swear outburst. Maybe it will do the trick for his sister."

Easy pickings for last year's semi-finalist Grigor Dimitrov on No.1, as he moves into a commanding second set lead against Argentina's Federico Delbonis. The man who knocked out Andy Murray in the quarter-finals a year ago is out at 11 in the seedings but he's looking good for Wednesday's second round.

Britain's Johanna Konta has been on Twitter following her defeat against Maria Sharapova on Centre Court.

She said: "What an incredible experience today! Thank you AELTC Wimbledon for the opportunity to play on such a stage. Doubles next!!"

"Duque-Marino took plenty of risks in that tie-break but it paid off. Both players have had issues seeing the ball due to the sun here on court three."

Into the 'breaker on Court Three, as we seek one of the great days in Broady family history. But a poor backhand drop shot on set point down limps into the net, and Duque-Marino has pocketed the first set.

Reflecting on her 6-4, 6-1 victory over Russia's Margarita Gasparyan, Serena Williams told BBC Radio 5 live: "People keep asking about the Grand Slam and the 'Serena Slam'. I've never really thought about the Grand Slam of tournaments, but that would be the ultimate dream."

Andrew Castle
BBC tennis commentator

"That's a good response after the disappointment of losing a set point the previous game. Broady is playing well here."

"Two women sat in the court three sun are decked out in the Colombian national colour of yellow, blue and red - yes, they are supporting Mariana Duque-Marino. But they are outnumbered by about a few hundred to one.

"The South American pair whoop as British number three Naomi Broady sees a set point go begging when she overcooks return. Then, cheer again when their player fights back to win in deuce.

"The rest of crowd groan. Nicely poised though."

The Centre Court crowd have been lobbed another tasty morsel from the referee's office.

Sloane Stephens v Barbora Strycova has been shunted onto the main stage.

Stan Wawrinka told BBC Radio 5 live: "It was a great start and I'm happy to win the first match here. The most important thing is to get through and I'll continue to work at my game. Winning the French Open has given me a lot of confidence for sure, but everyone starts from zero in this tournament. I'm going to rest up and be ready for the next game.

"I'm playing some of the best tennis of my career, every piece of the puzzle is fitting together and hopefully there's still more to come from me."

Richard Krajicek
1996 Wimbledon champion on BBC Radio 5 live

"I don't think many of Stan's opponents are going to be hunting out the DVD of this performance to see how well he's played, because he hasn't.

"But that doesn't really matter as long as he progresses. I think he'll be at a much higher level by the time he reaches the latter part of the tournament."

Great Britain Federation Cup captain Judy Murray is one of those in the crowd watching Naomi Broady on court three.
