SOUTH WILLIAMSPORT, Pa. (AP) — Hawaii's coaches lay sprawled on the field as their happy players trotted around showing off their new championship banner.

Winning the Little League World Series can be exhausting.

Tanner Tokunaga hit two homers, Iolana Akau added a solo blast and Waipahu, Hawaii, took advantage of several miscues by Matamoros, Mexico, in 12-3 victory Sunday that sealed the fourth straight Little League title for the United States.

"I know I'm tired," manager Timo Donahue said. "I'll probably catch up on a lot of sleep the next few days."

His pint-sized players wore out Mexico, too. It was just the second time in series history that a team scored in each inning in the title game, with the 1974 team from Taiwan the only other squad to accomplish the feat.

Two Hawaii runs Sunday scored on passed balls, and another run came home on a bases-loaded walk. Mexico committed three errors.

Still, Mexico's lineup is loaded with dangerous hitters, so the lead wasn't safe until reliever Christian Donahue, the manager's son, got Fernando Villegas to ground out to Tokunaga at shortstop.
