What happened: Cardinals pitcher Michael McGreevy hosted local families connected to the ALS Association at Busch Stadium as part of Lou Gehrig Day. He held the event to honor his grandfather, Joe, who died from the disease. The gathering tied the team's day to the leaguewide commemoration of Lou Gehrig.

Why it matters: Lou Gehrig Day is observed across MLB to recognize those affected by ALS, and player-led efforts like McGreevy's give the date a personal dimension. Honoring a family member lost to the disease connects the club's platform to a cause that resonates well beyond the field.

What to watch: Watch for follow-up from the Cardinals and the ALS Association on the visit, and for similar Lou Gehrig Day tributes around the league.
