Major League Baseball players will honor victims of last week's shooting by wearing Marjory Stoneman Douglas High School hats this week at spring training games.

Rob Manfred said all 30 teams were confirmed to wear the school hats during pregame warm-ups for their exhibition openers. Players, managers, coaches and umpires will have the option of wearing the caps during those first games. The hats might later be signed and auctioned to raise money for the Broward Education Foundation, the official victims fund.

Manfred said MLB received a "really strong sentiment of the clubs it was the appropriate thing to do immediately.''
