ST. LOUIS (KSDK) - Three St. Louis Cardinals players coached some young players Friday.

Matt Holliday, David Freese, and Allen Craig, all co-chairs for Homers for Health, attended the Home Run Derby Championships in Forest Park, benefitting SSM Cardinal Glennon Children's Medical Center.

Students from 35 area schools fundraised more than $20,000 for Homers for Health. Twenty-six schools held a waffle ball home run derby contest, and the winners of those contests participated in the event Friday.

The students were coached by the Cardinals players and posed for pictures with them.

More than 900 people attended the event.
