Played wrong ball | Golf Monthly

When you played the provisional ball from a spot nearer the hole, your original ball was no longer in play, ie, the provisional ball became your ball in play when you played it. The two stroke penalty for playing a wrong ball is still in effect, Your score for the hole was 7,
1 - original tee shot
1 ps for stroke and distance
1 - stroke made with provisional from tee
2 ps for playing wrong ball
2 putts
