PEORIA, Ariz. — The Mariners’ game on April 15 against the Dodgers in Los Angeles was designated Monday by Major League Baseball as the annual Civil Rights Game.
The Civil Rights Game dates to 2007 and seeks to pay tribute to those connected to the nation’s civil rights movement, but this marks the first time it will be held in conjunction with annual Jackie Robinson Day observance.
Baseball began honoring Robinson each year in 2004 on the anniversary of his debut for the Brooklyn Dodgers, which marked the breaking of the sport’s color barrier.
All clubs take part each year in Jackie Robinson Day ceremonies, which include having all field personnel wear Robinson’s No. 42. This is the first time the Mariners will participate in the Civil Rights Game.
