Warner Robins, Georgia's Dalton Carriker (2) rounds second after hitting a walk-off solo homer in the eighth inning against Tokyo, Japan in the Little League World Series Championship baseball game Sunday in Williamsport.

SOUTH WILLIAMSPORT — Dalton Carriker couldn't believe it. He had just hit a home run to win the Little League World Series.

"I almost fainted," the 12-year-old shortstop with braces said after his eighth-inning blast gave Warner Robins, Ga., a thrilling 3-2 win over Tokyo on Sunday to win youth baseball's biggest prize.

"Wow, I never thought this could happen," Carriker said.

His dramatic homer over the right-field wall off Japan's Junsho Kiuchi gave the United States three straight Little League championships.

"USA! USA!" cried the Georgia-partisan crowd as dozens of fans waved American flags. Columbus, Ga., won the crown last year, and Ewa Beach, Hawaii, in 2005.

"I'm very honored to be associated with these young men," an emotional manager Mickey Lay said. His eyes welled with tears during a post-game news conference.

"There are only several times in your life, when people come into your life and touch you emotionally," he said, "and they get into your heart and never leave."

Jubilant Georgia players hugged Carriker as he reached the plate following the homer. Lay lost his hat after joining the team in celebration following a tense game marked by excellent pitching.

Georgia reliever Kendall Scott struck out 10 and allowed one hit over five-plus innings to quiet Japan's bats after Georgia fell behind 2-0 early.

Scott had watched Japan's impressive hitters throughout the tournament.

"Going out there today, throwing the ball, I was scared to death on the first pitch," he said.

Scott left the game in the top of the eighth, with Zane Conlon getting the last out.
