Peck quit his job of 18 years to dedicate his full attention to this project. He enlisted the services of Anthony Filippis Sr., who co-founded the medical supply company, Wright & Filippis.
Filippis, who dedicated his life to helping people with disabilities to live sustainable lives, donated $30,000 to help Peck get the league off the ground.
Peck acquired land from the city of Southfield, raised $800,000 from corporate and individual sponsorships and began building the first field for the Miracle League of Michigan, which was completed in six months and ready for play in 2004.
Watch: The Miracle League
On the field, the bases are built into the synthetic rubber surface, the balls are made of rubber and the bats are plastic. The players are assigned "buddies" who are paired with individual children as an able-bodied friend to assist them on and off the field.
During games, every child gets a chance to hit, run the bases and score a run. The games last two innings with no balls or strikes called, and no scores are kept.
"I've always called it a win, win, win." Peck said. "It's a win for these kids because we dress them up in Major League jerseys, hats and baseball pants so they look like any other ball player. They're ecstatic that they can come out and do something they wanted to, but couldn't.
"The other wins are the families. Most of our dreams come true, most of us played little league sports, but for this segment of the population, their dream went away. Well, their dream is back now. The dads can be coaches. The parents are in the stands, just like any other typical family being very proud of their kids."
The third win, according to Peck, is by the "buddies" because they get an opportunity to change children's lives by helping them feel like they are part of a team.
Red Wings and Tigers director of community impact Kevin Brown said Peck embodies what the Game Changers program is about, dedicating his time and resources to his cause and getting hundreds of members of the community involved as well.
"This month's Game Changers are championing access and opportunity for thousands of disabled Michiganders, and Stephen Peck is helping lead the way for those who want to play baseball," Brown said. "Through the Easterseals Miracle League of Michigan, Stephen has dedicated nearly 20 years to growing the game by delivering a Major League experience for children with physical or cognitive disabilities."
