The slugger, hitting .769 entering Sunday's game, was 0-for-2 with a walk when he came up in the eighth.
He said a little prayer before settling himself in the batter's box.
"God, please give me the strength to get a hit and help my team out," Carriker said in recounting his prayer.
There was no doubt about his opposite-field shot off Kiuchi, which easily cleared the right-field fence 225 feet away from the plate.
And this is what makes Baseball so special. Its a game where both big and small kids prayers are answered.
Congratulations Little League World Series Champions of Warner Robins, Georgia.
