In Match Play, what can a player do if their opponent plays out of turn?

In Match Play, when a player’s opponent plays out of turn, the correct course of action is to cancel that stroke. The rules of Match Play state that players are entitled to have their turn honored, and if an opponent plays before it's their turn, that stroke is not valid. The opposing player can call attention to the error, and the stroke taken out of turn may be disregarded, allowing the player whose turn it actually was to play. This fosters fairness in the match by ensuring that players follow the proper sequence in taking their shots.

The other potential answers do not accurately reflect the appropriate actions allowed under the rules of Match Play. Allowing the shot to stand would not maintain the integrity of the game, while requiring the shot to count contradicts the very basis of turn-taking in Match Play. Ultimately, imposing a penalty stroke does not apply in this scenario, as there is no infraction requiring a penalty; rather, it's about the order of play. Thus, cancelling the stroke played out of turn is the correct and fair method of resolution in this situation.
