Today is Jackie Robinson Day. Every player in Major League Baseball wears his number, 42, which has been retired from all of baseball. (Only one ballplayer still puts on the number every day: Mariano Rivera.) It’s a day to reflect on Robinson’s legacy. His importance cannot be overstated. From the sports world to “the real world,” everyone knows this. President Obama knows this. Hank Aaron knows this. It is unfortunate that the Mets new Citi Field had to be saddled with its corporate moniker. Jackie Robinson Field sounds so much better. Almost exactly 150 years after the first shots of The War Between the States, which changed everything for this country, and 64 years from the time you put on the uniform of the Brooklyn Dodgers to grace major-league ball fields, making them into real fields of dreams for everyone, you did us proud: the best America has to offer. We honor you, Jack Roosevelt Robinson.
