An honor student at Mid-Pacific Institute where he just entered the eighth grade, Harrison leaves his 'Ewa home by 6 a.m. each school day to arrive on time, said his father, Andy Kam. He'll sleep as his mother drives and eat breakfast in the car before he reaches Manoa.

The after-school scramble back home for baseball practice is not any easier. Often, they arrive "just in the nick of time," Andy Kam said.

Dinner is often take-out, and then it's schoolwork from 8 p.m. to 11 p.m.

Baseball is intertwined with everything Harrison does.

"Our team practices so much, that is where he spends much of his spare time and he doesn't seem to have a lot of spare time," said Andy Kam, a financial planner.

He does have other interests: art, espeically drawing, and video games.

Harrison, an only child, began playing baseball when he was 8 years old.

Because he's so small, Harrison is not known for his big hits, his father said.

"But he puts the ball in play," he said. "We call him 'The Hammer.' Everyone knows him as that."
