There was an unbelievable moment at a baseball field in Aurora on Wednesday night.

A dream came true for a boy whose main goal in life was to play baseball, but his genetic disorder and a wheelchair made that nearly impossible.

Against the odds, Harrison Spiers wasn’t about to give up.

The 17-year-old Aurora Grandview High School senior asked for someone to help him hit the ball, and his friends at the Church of Jesus Christ of Latter Day Saints stepped up to the plate.

They modified a clay pigeon thrower to hold a bat.

Harrison, who goes by the nickname H-Man, then used a chord to trigger the bat as a ball is thrown.

“We actually drew pictures of it before it got built," Harrison's father Jeff said. "And to actually see it in real life…is real exciting.”

Getting the contraption to work took a lot of love.

Jeff said his son has dreamed about baseball his whole life, but has never had the chance to play.

Mother Alicia Spiers said church members, “worked so hard to make it come true”.

When 9NEWS reporter Vicente Arenas told Harrison he looked good on the field, he responded with a smile.

"Yeah," he agreed.

For him the game is real.

"He's been to countless games for his brothers," Jeff said. "He's yelled at umpires and he's screamed from the stands. Called the balls and strikes. Today is his turn.”

Now, H-man is hoping to qualify to play in a more competitive league since he’s now able to hit a pitched ball.

His genetic disorder may have taken over his body, but not his determination and love of baseball.

His parents say he insisted on wearing a helmet during Wednesday’s game.

He also asked for cleats.

He may have them for tryouts next spring.
