Can a player use another player's ball during a round?

The assertion that a player can use another player's ball during a round is accurate when it states that it must be a conforming ball. According to the Rules of Golf, a player is permitted to use a ball that is not their own during a round, provided that the ball conforms to the specifications outlined by the governing bodies, such as the USGA and R&A. This means that as long as the ball meets the criteria for size, weight, and overall performance as defined in the rules, it can be used without penalty.

The importance of conforming balls relates back to fairness and uniformity in play; non-conforming balls could alter the game dynamics and provide advantages that other players may not have. Therefore, the idea here is to ensure that all players play under the same conditions, relying on equipment that adheres to the established regulations.

The notion that a player must use their own ball is incorrect in this context. Players often may find themselves in situations where they do not have an extra ball and can borrow one from a fellow competitor, as long as it is conforming.
