On Sunday, Major League Baseball will celebrate the 71st anniversary of Jackie Robinson Day, which marks the day Jackie Robinson broke the color barrier in 1947.
MLB has honored Robinson on April 15 since 2004, and it has been customary since 2009 for every person in uniform to wear Robinson's No. 42 on the field.
That will once again be the case Sunday as MLB reflects on Robinson's debut with the Brooklyn Dodgers to become the first African American player in league history.
In addition to donning No. 42, each player will also wear hats with a special patch honoring Robinson, as seen in this tweet courtesy of New Era Cap:
