Jameis Winston ain't the only superstar athlete in his family -- his 7-year-old brother is already a "damn superstar" ... so says the president of the kid's youth baseball league.
Jameis has already publicly touted his lil' bro Jonah Winston as a "Young Jeter" ... and according to Steve Crim, who runs the Hueytown Dixie Youth Baseball League -- Jameis is right.
"Jonah is a damn superstar," Crim says ... "You can't catch him, can't strike him out, can't stop him. For a 7-year-old, he's a true phenom. He is that good."
Crim says Jonah isn;t just a stud on the diamond -- he's crushing it in football and basketball too ... "He's one of the best kids out here. Just a true athlete and he's a really good little kid to. People really care about him."
Of course, Jonah is getting some major support from Jameis -- who's been taking in some games recently and posting the highlights online ... and it's clear the kid can play.
"Jonah can be a future pro one day just like his big brother ... in any sport really."
