A trio of basketball-playing siblings from California have put the NBA on alert with a series of high-scoring performances that have grabbed national attention.

Lonzo Ball, 19, younger brother LiAngelo Ball, 18, and LaMelo Ball, 15, rose to prominence while playing together on their high school team in Chino Hills, roughly 36 miles (57 kilometers) east of Los Angeles.

So far, 19-year-old Lonzo has garnered the most interest after an impressive freshman season in college basketball with UCLA, where he has averaged 15.1 points and 7.8 assists per game. 

The 6ft 6in (1.98m) point guard is widely seen as being one of the most sought-after talents in this year's NBA Draft, likely to be chosen either first or second overall.

One mock draft projection has Ball being selected by the Los Angeles Lakers, the iconic NBA franchise who are rebuilding after lurching from one catastrophic campaign to another in recent years.

But Lonzo's displays have almost been outshone by the performances of his younger brothers who have continued to shine back in the world of high school basketball with Chino Hills.

On Tuesday, LaMelo served notice of his burgeoning talent by scoring an incredible 92 points in a 146-123 win over Los Osos, going 30-for-39 from two-point range.

LaMelo stepped up to lead the scoring with LiAngelo -- who in December posted 72 points in a game -- sitting on the sidelines nursing an injured ankle. 

LaMelo's extraordinary scoring feat came just days after Chino Hills saw the end of their 60-game winning streak.

"Well I mean that's one way to bounce back after a loss,... I see you little bro 92," big brother Lonzo wrote on Twitter.

The performance also got the attention of the professional sports world, with NFL stars Jared Goff and Todd Gurley of the Los Angeles Rams and Los Angeles Dodgers center fielder Joc Pederson taking to Twitter to wax about his talents.

"Wow, kid can absolutely ball," was the verdict of Rams quarterback Goff.

The Ball brothers' precocious rise has been overseen by father LaVar, a towering former NFL player with the New York Jets, who runs a successful personal training business. The boys' mother, Tina, a former college basketball player who is now a school athletic director, has also guided their careers.

"I tell my boys all the time, someone has to be better than (Michael) Jordan. Why not you?" LaVar told the Maxpreps.com website.

"You got everything. Everything. We give them everything because of the work they put in. They don't take off holidays. No Christmas. Nothing." 

Ball Sr. ensured that all three boys committed to UCLA early. It is part of a long-term career path he had mapped out more or less since his children were old enough to start playing basketball.

"These boys were born to go pro," LaVar Ball said in a 2016 interview. 

"Your mom's a P.E. teacher, I'm a personal trainer, your last name is Ball. How much more lined up can you be?

"They're built for this. When the boys were seven, nine, and ten, they'd play against the eighth graders and they'd run 'em into the ground. Soon kids would want them to sign their backpacks or their basketballs. Melo was so young, he'd just sign with an X."

While all three brothers are earning their share of the attention, Lonzo will be the first to gain a foothold on the national stage when he is drafted this year.

"His vision is absolutely elite," Josh Gershon, a national scout for the Scout.com website said last year.

"There haven't been too many players in high school basketball history that have come along with his skill set, his versatility, his size for the position."
