In four-ball stroke play, if a player is late for their tee time, what happens?

In four-ball stroke play, if a player is late for their tee time, the correct outcome is that the late player may join play on the 5th hole without penalty. This rule acknowledges that while punctuality is important, the overall integrity of the match is preserved by allowing the late player to join their partner once they are able to. This approach differentiates four-ball play from stroke play formats where penalties for lateness might be more severe.

It's important to note that the partner can continue playing in the meantime, ensuring that the competition proceeds. Other options imply more serious consequences that do not align with the established regulations for four-ball stroke play regarding late arrivals. The allowance for the late player to join at the 5th hole elegantly balances both the competitive integrity of the game and the need for players to adhere to schedules.
