42 because it's Jackie robinsons number and every team has it retired (there will never be another #42, ever)
The above answer is absolutely correct as no player in MLB, once Mariano Rivera of the Yankees retires, will ever wear the #42 again.
The number that has been retired by the most teams, other than #42, is #20 which has been retired by 9 teams ... Reds (Frank Robinson), Orioles (also Frank Robinson), Dodgers (Don Sutton), Giants (Monte Irvin), Cardinals (Lou Brock), Royals (Frank White), Phillies (Mike Schmidt), Diamondbacks (Luis Gonzalez), and Pirates (Pie Traynor).
The number 42 was retired on all teams for Jackie Robinson on April 15th, 1997. Mariano Rivera on the New York Yankees is the last active player to wear the number.
The New York Yankee Baseball team was the first one to retire the numbers of their great players after they retired.
