The sweet reason why Kyle Schwarber wears a green wristband during games

CLEVELAND -- During Wednesday night's World Series game, Cubs designated hitter Kyle Schwarber was spotted wearing a green wristband to honor a young boy with a rare genetic disease.

Campbell Faulkner of Cave Creek, Ariz., has a mitochondrial disease, but that doesn't stop the 10-year-old from loving baseball. Faulkner met Schwarber two years ago during spring training, and the two have since developed a bond. The pair even saw each other just days before Schwarber lead the Cubs to a victory in World Series Game 2.

Faulkner has a team of 13 doctors and often struggles to stand and walk for long periods of time. He also missed nearly 100 days of school last year due to his illness. Schwarber said he is inspired by how Campbell always has a smile on his face even though he has so much to overcome.
