Baseball retirements refer to the end of a professional baseball player's career. This is usually marked by a formal announcement or ceremony, and the player's jersey number is often retired in their honor. The term 'OUTS' is used in baseball to describe when a batter is out, either by being tagged out, thrown out, or forced out. In this context, OUTS can be seen as a metaphor for retirement, as the player is no longer able to participate in the game.
