provisional

Question
what is the ruling if an opponet hits the provisional ball i hit after i have alraedy found and played my first tee shot

Answer
Norman,

This is a good question and here is the answer. Your opponent would have hit a "wrong ball".

Under Rule 15 from the USGA web site here are the steps to follow. This is for a stroke play competition.

b. Stroke Play

If a competitor makes a stroke or strokes at a wrong ball, he incurs a penalty of two strokes.

The competitor must correct his mistake by playing the correct ball or by proceeding under the Rules. If he fails to correct his mistake before making a stroke on the next teeing ground or, in the case of the last hole of the round, fails to declare his intention to correct his mistake before leaving the putting green,he is disqualified.

strokes made by a competitor with a wrong ball do not count in his score. If the wrong ball belongs to another competitor, its owner must place a ball on the spot from which the wrong ball was first played.

Exception: There is no penalty if a competitor makes a stroke at a wrong ball that is moving in water in a water hazard. Any strokes made at a wrong ball moving in water in a water hazard do not count in the competitor's score.

(Lie of ball to be placed or replaced altered - see Rule 20-3b.)
(Spot not determinable - see Rule 20-3c.)

Hope this helps.
