A caddie is a person who assists a golfer by carrying their clubs and providing support during a round of golf. Caddies help golfers by offering advice on club selection, reading greens, and keeping track of scores. They play an important role in the game, allowing golfers to focus on their performance. Caddies are often employed at golf courses and can be found working with both amateur and professional players. In professional tournaments, caddies may have extensive knowledge of the course and the game, making them valuable partners for golfers like Tiger Woods or Phil Mickelson.
