The MLB is honoring Hall of Famer Jackie Robinson, the first African American player to compete in the majors in the modern era.
April 15 is now a league-wide dedication to Robinson, and as such, all 30 teams will have their players wear the retired No. 42.
See the sights and hear from players around the league.
Proud to wear #42 tonight. Jackie Robinson will forever be the symbol of equality, leadership and perseverance in our great game. #42
