Another HUGE victory for Chad Johnson's 10-year-old track phenom daughter -- who just SMOKED EVERYBODY at the 800m race at the AAU National Championships ... TMZ Sports has learned.
Cha'iel Johnson -- aka Moca -- took home the gold against some of the finest 10-year-old runners in the country ... beating out the 2nd place finisher by more than 6 SECONDS!!!
By the way, her competitors are no joke ... these girls are some of the best young runners in the country.
But Moca is simply on another level -- and we previously reported, she's got her sights set on the Junior Olympics at the end of this month.
