CORAL SPRINGS, FLA. – Lexi Thompson is moving out. Not in the manner of so many 20-year-olds who might head to a big-box store to accessorize a shoe-box-sized dorm room or apartment. No, this multimillionaire is house-hunting in tony Jupiter, and her parents and younger brother will be moving in with her.

And so it goes with raising a prodigy. Ahead of the game in so many ways yet too young to rent a car unrestricted, buy a drink or wrap her head around the kind of money that flows through her bank account.

“My dad takes care of all of that,” she said of her finances.

“He’s like, You don’t even want to see how much money you give back (in taxes).” Scott and Judy Thompson have their Coral Springs home on the 12th hole at Eagle Trace for sale. It’s the only home Lexi and younger brother Curtis have known. Judy likes to tell potential buyers the house has good karma, having raised three professional golfers within its walls.

The plan is for mom and dad to help Lexi get settled and live with her until she turns 21. At that point, they’ll buy their own home locally and Curtis, 22, will stay on until he’s ready for his own digs.

It’s a tricky business, supporting three professional golfers on three tours. In early February, for example, Judy accompanied Lexi to the Bahamas while Scott caddied for Curtis in Colombia on the Web.com Tour. Meanwhile Nicholas, 32, topped the leaderboard after Round 1 of the PGA Tour’s Farmers Insurance Open in San Diego, where he was joined by wife Christen and 1½-year-old son, Nico.

“I get called ‘Lexi Thompson’s brother’ by everybody – players, fans,” Nicholas said. “You’re playing well, you’re in the top 10, I hear, ‘Oh, that’s Lexi Thompson’s brother.’ Somebody whispering 8 feet from you.”

Growing up Lexi – from the lanky, homeschooled teen who won on the LPGA at 16 to the now 6-foot stunner in bikiniclad photo shoots – is to mix the extraordinary with a sprinkling of normal.

“I chill with the best,” Lexi said.

One minute she’s buying a white Corvette (her second car), and the next she’s texting her mother from Chili’s asking for an appetizer coupon.

Success came quickly. The next step: making it last.

Lexi Thompson is staring at a pile of clothes on a hotel bed. A Puma rep and seamstress have gathered and altered 125 pieces from this year’s spring line – shirts, shorts, skorts, dresses and pants – to Thompson’s specs. She will try on each one to make sure nothing hugs too tight or hits too high above her tan lines.

Thompson, one of the fittest players on tour, is a big fan of elastic. She needs plenty of give to accommodate swing speeds of 105 mph and a towering, flexible frame.

Known for taking massive chunks of earth with each mighty blow, she is working to shallow out her swing to avoid wrist injuries.

“I’m trying to work on firing my hips more through impact,” she said. “That’s part of the steepness with my divots, because I can’t just keep my hips moving.”

As a perfectionist who is committed to fitness, Thompson paid particular attention this offseason to her upper left shoulder, working to strengthen and stabilize an area that was giving her knots.

“My day doesn’t feel right if I don’t work out,” Thompson said.

During her offseason break – one week, twice as long as last year’s – the family reunited for the holidays. Dad rounds out their foursome, though he rarely plays.

“He does everything for us: fills in our divots, cleans our clubs,” she said. “We call him our hard drive.”

They are a regimented, committed bunch, these Thompson golfers.

Three years ago, they spoke publicly for the first time about a family secret, revealing to Golf Channel that Nicholas is not Scott’s biological son. Judy’s first husband was Scott’s brother Curt, who died in a skiing accident in 1983, months after Nicholas was born. Scott and Judy married a couple of years later.

Growing up, the Thompson kids rode their bikes to the course each day, clubs in tow. Competition was rampant. When things became too heated, someone usually went home before the situation exploded.

“We always talked about it at dinner,” said Judy, who works as a dental hygienist. “We always had dinner at home around the table every night. That was one of my main requests.”

Her two youngest children were on the range during the recent Demo Day at Orange County National, busting drives for a crowd at the Cobra/Puma party. However, Curtis, a right-handed player, was hitting it from the other side.

“He can outdrive me lefty,” Lexi said proudly.

While Curtis cuts his teeth in the pro ranks, Lexi begins her fourth full season on the LPGA. After two events in Asia, she will play twice on the West Coast before defending her title in the ANA Inspiration, formerly known as the Kraft. Top American Stacy Lewis said what’s most impressive about Thompson’s length is that it’s all carry. Put her on a wet course and she can find spots in the fairway that no one else on tour can reach.

But the maturity of her game, Lewis said, isn’t yet on par with the likes of Inbee Park, Lydia Ko or Michelle Wie.

“Once she matures and figures out how to play different types of golf courses,” Lewis said, “then she’ll be the threat.”

Scott believes the hardest part so far has been finding the right caddie. (One quit on her last year during the fall Asia swing.) This time, Lexi made the decision.

“I picked the other two,” Scott said. “Maybe that was a mistake. I’m learning in this thing, too.”

There’s nothing terribly complicated about the quiet Thompson. She looks older now, with a darker, more natural hair color. She has started to dabble in poetry and enjoys the beach.

Her main focus is on developing consistency in her golf game, particularly on the greens. One gets the sense in talking with the former prodigy that she means to cram a Hall of Fame-type career into a short period of time.

“This is all she knows right now,” Curtis said. “She’ll play however many years it takes her to be well enough off for life, and then that’ll be it. She needs to enjoy life as much as anybody else does, not just the life of a professional.”

Growing up playing against older girls, Lexi was told by her mother that boys equal bogeys. That’s no longer the case, of course, though Lexi is single.

“It’s tough, with how much we travel and everything, to keep a relationship,” Lexi said. “But I mean, like, I’m looking for somebody that has a busy lifestyle, too. . . . I don’t really know for sure what I’m looking for yet.”

It seems only yesterday that a 12-year-old Lexi was practicing her autograph on the drive north to Pine Needles in North Carolina to compete in the U.S. Women’s Open.

“I don’t want to be playing to a certain age to where I can’t have a family,” Thompson said recently in reflecting on her long-term plans. “I want to be off the tour and have a family and a life beyond golf.”
