Umpires are individuals who officiate sporting events, such as baseball and softball. They are responsible for making sure that the rules of the game are followed and that the players abide by them. Umpires wear a vest to identify themselves as an official of the game. The vest is typically black and white and has the logo of the sport they are officiating on it. Umpires are also responsible for making calls on the field, such as balls and strikes, fair and foul balls, and safe and out calls. Umpires are an important part of any sporting event and are essential to the game's integrity.
