Grab your whiffle bat, step up to the plate and launch one out of the park at our Mansfield Home Run Derby. Registration is $20 and comes with a free t-shirt and other goodies, plus prizes for the winners of each age group. All proceeds go to the Team Hilliard Foundation, supporting research and awareness for ALS. The charity was founded by Sam Hilliard, a Mansfield High graduate and Major League ballplayer who tragically lost his father to the disease.
