On first impression, Johanna Konta’s short media appearance on Wednesday night after beating third-seed Simona Halep was quite unlike the thrilling three-set match itself: entirely unremarkable.

“I just stayed very present and fought very hard for every point,” the level-headed Konta smiled, just minutes after becoming the first British women to qualify for the semi-finals of the Miami Open.

“I am just happy to still be part of the event and I know that when I play next it will be a tough game. I’m looking forward to being a part of it.”

Of more interest than her actual comments was rather the startling consistency of them. Two years ago, Konta burst onto the scene with an impressive run at the Eastbourne International, handing bloody noses to players ranked No 34, No 8 and No 20 in the world, only a couple of weeks before Wimbledon. Fans were understandably excited.

But Konta remained impassive throughout, her short press appearances in a portakabin tucked away at the back of the Devonshire Park Lawn Tennis Club remarkably similar to the cool conferences she holds now.

“I did well to stay in the present and push my level to be with hers,” Konta said after a particularly impressive win over Garbiñe Muguruza, in comments almost identical to those she made in Miami this week.

“I feel very fortunate and happy to still be here and I know the next match will be difficult but all I can do is my best. I’m sure it will be special.”

Both off the court and on it – “I can't remember playing someone like this on that level, that consistent for the whole match,” a disbelieving Agnieszka Radwanska said at the start of this year after being swotted aside in straight sets in the final of the Sydney International – Konta is a model of consistency. That is to her credit.

When it comes to the success of British Tennis over the last two years, Konta is very much the yin to Andy Murray’s yang. For while Murray rarely finds himself out of the headlines, on account of both his brilliantly tempestuous performances on the court and his witheringly frank comments off it, Konta goes about her business in a far more understated style.

The 25-year-old prides herself on remaining utterly impassive on court, seems utterly unfazed by pressure on any level and can often be heard answering journalists’ questions by enthusiastically discussing her “process”.

She has worked extensively on the mental side of her game and credits replacing a previously ‘highly-strung demeanour’ with a newly sanguine approach as the biggest reason behind her seemingly rapid ascension to one of the world’s best players.

That her success has continued into the new season despite two apparent setbacks in December last year – one surprising in nature, one utterly tragic – is further testament to her strength of will. First she surprisingly parted company with her coach Esteban Carril; a month later, her sports psychologist Juan Coto – so essential to her improvement – died suddenly, aged just 47.

As far as her tennis goes, Konta appears to have recovered from this dismal end to the year. She made it to the quarter-finals of the Australian Open in January, her second best performance at a Grand Slam, and is currently playing some fine tennis in Miami, after an especially busy couple of months.

AFP/Getty Maria Sharapova's comeback divides opinion Eugenie Bouchard She’s a cheater and to me, I don’t think a cheater in any sport should be allowed to play that sport again.. I think from the WTA it sends the wrong message to young kids: ‘Cheat and we’ll welcome you back with open arms’. Getty Maria Sharapova's comeback divides opinion Caroline Wozniacki "First of all I think she's a good draw for tennis, women's tennis in general. But two, I think it's questionable allowing - no matter who it is - a player that is still banned to play a tournament that week. So from the tournament side I think it's disrespectful to the other players and the WTA. Obviously rules are twisted and turned in favour of who wants to do what." Getty Maria Sharapova's comeback divides opinion Victoria Azarenka "She has such a huge fanbase and obviously that's going to bring more attraction to see how she will do, so I think it's good for tennis, good entertainment." Getty Maria Sharapova's comeback divides opinion Dominika Cibulkova “I don’t think it is right but what can we do about it? She’s still banned but she can come on site on Wednesday, that’s pretty strange." Getty Maria Sharapova's comeback divides opinion Angelique Kerber "It's a little bit strange for the players that she can walk on site on Wednesday and she can play on Wednesday." Getty Maria Sharapova's comeback divides opinion Heather Watson “From the tournament standpoint, she will bring in the crowds and make money. But, from a moral standpoint, you should have to work your way back up if you've been on a ban. It just seems a bit easy.” Getty Maria Sharapova's comeback divides opinion Simona Halep "Her return is good for tennis, she is impatient, she wants to play and win." Getty Maria Sharapova's comeback divides opinion Venus Williams "I think the bodies have made their decision, and she has an opportunity to come back and continue her career. I think she should be allowed to continue that. If people want to give her wildcards, I guess that's the tournaments' decision as they weigh other wildcards. It will be nice to have her back in the game." Getty Maria Sharapova's comeback divides opinion Svetlana Kuznetsova "I understand, because if we talk about cheaters, people who cheat, you would say, 'Why would cheaters get a wildcard?'. But then if there is some mistake, you know, it's a little bit of a different story." Getty Maria Sharapova's comeback divides opinion Andy Murray "I think you should really have to work your way back." Getty Maria Sharapova's comeback divides opinion Roger Federer "It´s a tough one. What do you want me to tell you? Like you said, because it´s the first, it kind of is what it is. You know, some people will like it; some people won´t. She paid the price for what she did, so that´s all you can say there." Getty Maria Sharapova's comeback divides opinion Jo-Wilfried Tsonga "It's like if you give a sweet to a kid who did a bad thing, it's going to do it again. It sends the wrong message." Getty Maria Sharapova's comeback divides opinion Andy Roddick "If there's a smaller event that will benefit from having Maria, I don't begrudge them giving her the card. The Grand Slams are different. They're held to a higher standard because there's so much interest in them." Getty Maria Sharapova's comeback divides opinion Nick Kyrgios "I'm anti-anything that's performance-enhancing, massively against it. I'm not the one to say what [violators] should -- or shouldn't -- get afterwards, but it doesn't make sense to support people who cheat."

Getty Maria Sharapova's comeback divides opinion And as for Maria herself? “I can’t control what people say. To have nicer things to say about me in press conferences, what will that change to my tennis?" Getty

Indeed, while any young British player would do well to slump in front of a television with a large collection of Murray videotapes, closely studying the Scot’s imperious technique and shot-selection, Konta surely sets the far better example when it comes to the mental side of the sport.

Hers is also an approach that the likes of Heather Watson and Laura Robson would do well to follow. Watson, the British number two, is undoubtedly talented but has a frustrating tendency to become embroiled in gruelling three-setters; she struggles to close matches out in a similar fashion to the younger Konta.

Robson meanwhile has struggled desperately in her attempt to reclaim the world-class ranking that a wrist injury cruelly deprived her of. It therefore came as no real surprise when the 23-year-old said she was turning to sports psychology in the wake of a disappointing straight sets loss in the first round of qualifying for this year’s Australian Open.

“I have started working with a really good guy but it’s not an overnight change,” Robson acknowledged at the time. “I wish there was a switch that could just be flicked but it’s not just going to happen overnight.”

The pair will join up with Konta when the Great British Fed Cup travel to Constanța to play Romania in the World Group II Play-offs, by which point there is a very real chance Konta will have added the Miami Open to her Sydney International success from earlier this season.

Predictably, Konta remains as business-like as ever about her chances in Key Biscayne, simply commenting “I am looking forward to the next round and I know that it is going to be a tough one,” when asked about her chances against Venus Williams in tomorrow’s semi-final. Either Caroline Wozniacki or Karolína Plíšková waits in the final.
