It was 66 years ago today, that Jackie Robinson put on his infamous #42 Brooklyn Dodgers jersey, and all around the league, every team pays tribute to him by wearing #42.

According to RedSox.com, the Red Sox and Rays dressed in uniforms donning No. 42 for Monday's game at Fenway Park, and the Red Sox will again wear No. 42 Tuesday in Cleveland.

In 1997, under the direction of Commissioner Bud Selig, Robinson's No. 42 was retired across all of Major League Baseball in an unprecedented tribute. The only active player who still wears #42 on a regular basis is Yankees closer Mariano Rivera.
