League play for the company I work for.
Opponent thinks he looses ball. Takes a drop and hits that shot. Then finds his original ball that he thought he had lost. He hits the original ball. We(my team) had a problem with it but did not know the actual ruling. Due to time and us not knowing the ruling he played his original ball that he thought he had lost. We(the foursome) were thinking about letting him play both balls out, and let the offical score keeper rule it but due to time he played only his original ball that he thought he lost. Got a 6 on a par 5.
