Despite popular belief that it was his Little League number...it was not. Ichiro was issued number 51 when he joined the Mariner's as a rookie. Later on after he had shown that he was a prominent player not only for the Mariner's but one of the best in MLB he was offered a lower number. The lower number was '07'. Ichiro declined the lower number '07' and stays number '51' to this day.
