This isn’t a team logo, but rather the 2011 version of the logo commemorating “Jackie Robinson Day”, that day being April 15th, a day which major league baseball uses annually to honor the man who bravely broke baseball’s color line when he played his first game for the Brooklyn Dodgers on the date in 1947. Commissioner Bud Selig first designated April 15th as “Jackie Robinson Day” in 2004, and it has become a yearly tradition. Robinson’s jersey number 42 was permanently retired from all of baseball by Selig, but each year on April 15th, every major league player wears the number to honor Robinson.
