Q: A player's ball came to rest 20 yards over a green and beyond a white stake which the player's caddie said was a boundary stake. The player played a provisional ball which came to rest short of the green, but closer to the hole than his original ball. The player played the provisional ball onto the green. At that point, he walked behind the green towards his original ball, which had been visible all along, and discovered that the white stake was not a boundary stake and that his original ball was in bounds. What is the ruling?
A: The player should have determined the status of his original ball before playing a second stroke with the provisional ball and, since the original ball was not out of bounds, he should have abandoned the provisional ball. When he failed to do so, the second stroke with the provisional ball was a stroke with a wrong ball – Rule 27-2c.
In match play, the player lost the hole (Rule 15-3a).
In stroke play, he incurred a two-stroke penalty (Rule 15-3b) and was required to hole out with the original ball.
后来我们再看了一遍原文，发现，我们又再一次成为粗心的马大哈。原文中说打了球进了（误以为是界外）的桩外面，并且一直都可以看得到球（his original ball, which had beed visible all along）！所以，在这样的情况之下球手有责任去确认他的球的状态是不是已经OB了，没有OB的话而他的球却一直都看得到，不算lost ball，所以无法按27-2b进行处置，打了球也就违反了15-3a或15-3b。
