Last summer, the Anderson Monarchs, a Philadelphia baseball team that featured the Little League World Series star Mo’ne Davis, barnstormed through the South. They played baseball, and they also toured sites significant to the civil rights movement as a nod to the team’s heritage — it is named, after all, for the Kansas City Monarchs, the Negro leagues club for which Jackie Robinson once played.

“I stood where Martin Luther King and John Lewis stood,” wrote outfielder Myles Eaddy on a team blog after a visit to Selma, Ala., adding, “It is really cool to know how far we have come.”

Nearly a year later, the team’s trip has helped inspire an apology being extended by Philadelphia to Robinson, who broke Major League Baseball’s color barrier when he made his debut for the Brooklyn Dodgers at the start of the 1947 season.

The apology comes as Major League Baseball, on Friday, celebrates the 69th anniversary of Robinson’s first game with the Dodgers with its Jackie Robinson Day, initiated in 2004. Every major league player wears Robinson’s No. 42, an annual sight in baseball. What is different this year is the apology from the City of Philadelphia for the manner in which the Phillies treated Robinson when he began his career.
