If going up against little kids on the basketball court was an Olympic sport, Caitlin Clark would certainly make the team ... 'cause the Indiana Fever superstar blocked the hell outta a youngin' at a charity event!!
The hilarious highlight went down at Gainbridge's Habitat for Humanity event this week ... when CC playfully went 1-on-1 with a lucky fan in attendance.
In a clip from the gathering, the boy is shown dribbling up the court as Clark played D ... and even though he was barely 3-feet tall, he pulled up with a shot attempt over the 6-foot guard.
