Her name is Jaden Newman and this video shows her dominating a high school varsity basketball team.
A stand out player in high school basketball might not be rare, but as you can probably tell, Newman isn't 17 or 18 like most of her opponents presumably are, she is a nine-year-old currently in the 4th grade.
And this doesn't seem to be a one off either.
Apparently she currently averages nearly 15 points and 8 assists per game for Downey Christian high school in Florida.
Mind you, since when has the 4th grade been in high school - maybe the opposition will be searching the rule book!
