The most important date in baseball history is April 15, 1947, when Jackie Robinson debuted for the Brooklyn Dodgers and ended segregation in Major League Baseball.

The anniversary of that historic moment is coming up next week, but the celebration will begin this weekend. MLB Network has a full lineup of programming honoring baseball's most distinguished alum, beginning Saturday morning with an episode of the kid-focused program "Play Ball" that spotlights a conversation with Hall of Famer Ken Griffey Jr., discussing Robinson's legacy.

All-Time Games from various Jackie Robinson Days on April 15

Pirates at Cubs, 2017: The 70th Anniversary of Jackie Robinson Day. The Pirates were behind early, but they staged a thrilling comeback win that included a five-run seventh inning. Airs: 1 p.m. ET.

Giants at Dodgers, 2009: Who doesn't like a good old-fashioned walk-off walk? Giants closer Brian Wilson inherited a bases-loaded situation with no outs and walked James Loney to force home the winning run in the Dodgers' 5-4 win at Dodger Stadium. Airs: 4 p.m. ET.

Angels at Yankees, 2010: How poetic is it that a player named after Jackie Robinson absolutely rakes on Jackie Robinson Day? In this game, Robinson Canó -- yes, that's why his name is Robinson -- hit two home runs, recorded three RBIs on the day and led the Yankees to a 6-2 win. Airs: 8 p.m. ET.

Letters from Jackie

"Letters from Jackie" focuses on Robinson's role in the American civil rights movement, predominantly after he retired from baseball. Hosted by Curtis Granderson and narrated by actor Dennis Haysbert, the story is told in Robinson's own words, through correspondence he maintained during his lifetime with political figures, including Presidents Dwight D. Eisenhower and John F. Kennedy, and a young pen pal named Ron Rabinovitz, with whom Robinson kept in touch from 1955 to his death in '72. Airs: 7 p.m. ET.

The celebration will resume on Wednesday, the anniversary of Robinson's debut. MLB Network has a full slate of programming planned to commemorate the important date. They'll re-air the "Play Ball" episodes highlighting Jackie's career, as well as several All-Time games they first aired during Jackie Robinson weekend.
