The teenager in question is Holden Seguso and even that may not give the entire storyline away. Mum is Carling Bassett, from the Canadian brewing family, who stormed the breaches of tennis as a pretty-as-a-picture 15-year-old in 1982; Dad is Robert Seguso, Wimbledon doubles champion with Ken Flach in 1987 and 1988.

With those genes, it might be expected that Holden Seguso would have tennis thrust upon him but here, in the Luxilon Cup, the Nasdaq-100 Open’s junior championship, he is proving more than capable of handling the presumption that such progeny will necessarily be blessed with the talent of their parents. And it does not stop with him.

Seguso’s siblings, Carling, his 15-year-old sister, and Ridley, his 12-year-old brother — named after Ridley Scott, the film director — are talented players as well, though whether Mum and Dad are prepared to send all three of their children into a devilish world they know better than many, is a moot point. At least the Seguso kids know they will be armed with every bit of knowledge and experience their parents can impart.

According to Robert, his eldest son, who has just turned 18 years old, will be ready to make a significant impact when he puts on 20lb in in weight. The signs are — in the defeats of Marcus Fugate, his fellow American, and Philip Bester, of Canada — in the first two rounds here that Seguso Jr has the multifacted game required to make an impression, and he is even bowing to his father’s demands, as one would expect from a champion doubles player, to become more assertive in and around the net.

“He could go out there and hang all day with Guillermo Coria and do OK but to succeed he has to look to create more short balls and to come in, and you have to accept that you will make a lot of mistakes,” Robert said. “It’s trial and error. But when you see an opponent off balance, you have to know instinctively to dart in. It’s tough for him to accept that. He had a worse temperament than mine but these last two days are the best I’ve seen him. He has to learn to be more relaxed, not be p****ed when he misses a first serve, because too often he cramps up because he’s expending too much energy.”

When Holden was 14 and regarded as one of the finest of his age group in the world, he sprouted six inches in the space of one summer and such was the aggressive nature of the sport, he needed crutches to help him to walk around. He missed almost 18 months of tennis. By then, his parents agreed on a three-year commitment for Holden to live and practise at the renowned Nick Bollettieri Academy in Bradenton, on Florida’s west coast.

They have moved on to the campus, three doors down from Ivan Lendl, the former world No 1, four of whose five daughters have golf scholarships at the IMG Academy.

“There is access to everything there for us, it’s an incredible place,” Robert said. Carling, who teaches a small group of players, loves being one of the mothers, hanging out by the pool, the evenings spent in classy company, the delights of raising children. Is it really 22 years ago that she was reaching the US Open semifinals at 17? Holden describes her as the driving influence, his father the more mellow of the partnership. “If I didn’t play tennis, I’d be really depressed,” he says. “I can’t do anything else but this.”

Well, he can actually. He has picked up the basics of guitar in a couple of years and helps to pen lyrics, to the extent that for two hours each evening, he is up in his bedroom, singing away. Carling says that the melodies remind her of her fellow Canadian, the wonderful Gordon Lightfoot. “It is a bit scary how good these songs are,” she says. A proud mum indeed.
