Adams, who lives with his family in the St. Louis area in the off-season, will be at the organization's Teen Center of Excellence in Ferguson to spray the infield with free memberships.
From 6 to 8 p.m., Adams and his family will distribute 50 memberships to the first 50 teens who attend.
Along with the star swinging for new members, the event also will feature a home-run derby, a dance contest and baseball trivia.
