Jackie Robinson Day observance

Every Major League Baseball player, manager, coach and umpire wore No. 42 on Wednesday, April 15, as the sport marked Jackie Robinson Day across all 30 teams. (mlb.com) Major League Baseball said the 2026 observance marked the 79th anniversary of Robinson’s April 15, 1947 debut with the Brooklyn Dodgers, the game that broke modern baseball’s color barrier. All on-field personnel wore the number in Dodger Blue, and every cap carried a “42” side patch. (mlb.com) The league scheduled all 30 clubs to play on April 15 this year, putting the tribute in every ballpark on the same day. Major League Baseball announced that alignment when it released the 2026 regular-season schedule in August 2025. (mlb.com) Jackie Robinson Day has been a fixed date on the baseball calendar since 2004, and Major League Baseball’s MLB Together program says the league has asked every player and all on-field personnel to wear No. 42 on that date since 2009. (mlb.com) The number itself has a separate history. Commissioner Bud Selig retired No. 42 across Major League Baseball on April 15, 1997, making Robinson’s the first uniform number retired league-wide. (mlb.com) The one-day return of No. 42 grew out of Ken Griffey Jr.’s request to wear it on Jackie Robinson Day in 2007. Selig approved that request after consulting Rachel Robinson, then expanded the offer to other players; by 2009, the tribute covered everyone in uniform. (mlb.com) Major League Baseball added new 2026 elements around the games, including a “We Are Jackie” media campaign narrated by Hall of Famer CC Sabathia and a social media interview series with current and former players. The league also said players wore royal blue “42” socks from Stance. (mlb.com) Teams layered local events onto the league-wide uniform tribute. In Atlanta, children from the Jackie Robinson Boys & Girls Club of Cairo-Grady County were set to stand on the baselines before Braves-Marlins, while Arizona planned a $4,200 donation tied to Boys & Girls Clubs of the Valley. (mlb.com) The Jackie Robinson Museum in New York also opened Wednesday for special Jackie Robinson Day hours from 11:00 a.m. to 4:00 p.m. and invited youth baseball and softball players to an after-school community event.
