Matt Martin is 26 years old. People with Duchenne Muscular Dystrophy, which Martin is battling, usually only live to be 25 or 30. Nathan is nine years old and Thursday night, he and Matt were side by side at the Frisco Roughriders game. Nathan was diagnosed with Duchenne when he was five. Since Matt can't throw out ceremonial first pitches, but Nathan can, they took the mound together at Dr. Pepper Ballpark. They hope to spread their message in Major League Baseball, too.
