Speaking of the numbers on the baseball jerseys, the first baseball team to print the numbers on the jerseys is the work of an amateur baseball team in Cincinnati, USA
in 1833. (At that time, modern baseball was just formed in the United States, and even the American amateur baseball league ---The National Baseball Players
Association NABBP has not yet been established, let alone MLB), but this is only a legend so far, because there is no document to support it.
In 1916, the Cleveland Indians took the lead in printing numbers on the sleeves of their jerseys (but because the numbers on the sleeves were too small and
meaningless, they were soon put on hold), and in 1929, New York Yankee printed the number on the back of the jersey for the first time, ending MLB's 50-year history of no number on the back of the jersey.
But even though there was no number mark on the jersey at that time, the fans did not feel inconvenience when watching the game, because a player card was popular at that time, each player was serialized, and information such as scores and resumes were printed on the player card. Above, the sale of this player card has also become an important source of income for each team. During this period, it was also proposed to print the player's serial number on the jersey to facilitate the fans to identify, but many teams thought that this would lose a large amount of income and gave up, and many players thought that the number was written on the clothes, which is not the same as the prisoner. So, the players themselves are also resistant to this.
In 1929, the New York Yankees decided to arrange the numbers in the order of strikes and print the numbers on the back of the jersey. 1 stick is number 1, and 2 sticks are number 2, until the number 8 is the alternate catcher, and the pitcher uses it. The numbers are 11-21. The Indians also printed their jersey back numbers on their home game uniforms this year. Unlike the Yankees, the Indians’ 3-bar Howard’s jersey number is No. 5. They are not ranked in the order of attack.
An interesting anecdote, the Yankee's opening game on April 6th of this year was forced to be cancelled due to rain, and the Indians on the same day were playing at
home. Therefore, although the first decision was made on the back of the jersey The team with the number printed was the New York Yankees, but the first team to wear this jersey game was the Cleveland Indians.
Then in the second year, 1930, the Washington House of Lords (the predecessor of the Minnesota Twins) began to use the jersey back number. In 1931, all teams in the American League were required to use the jersey back number, but they could not use 13 number. At that time, 7 of the 8 teams in the American League followed their orders, except for the Oakland Athletics who are full of personality, because this team has a personality of the owner and head coach-Kenny Mark, he believes This behavior directly affected the team’s income from selling player cards and refused to implement the league’s requirements. This insistence lasted for 6 years. Until 1937, all teams in the American League used their jersey back numbers (the National League started in 1932). Used by all teams).
It is worth mentioning that in 1952, the Los Angeles Dodgers took the lead to print the number on the chest of the jersey. In 1960, the Chicago White Sox began to
print the player's name on the back of the number. In 1975, the Houston Astros even put the number on the pants. The player numbers were also printed, and the New York Yankees, who was the first to decide to use the jersey back number, have not printed their chest numbers and player names so far.
