I would suggest playing a round, and mentally keeping track of each and every throw. Then, when you are done, go back over the round in your mind, making notes on which shots kept you from achieving par on a hole.
Maybe you could check back in and let us know what you find out.
- Perhaps you'll see that you are hitting trees too soon on the fairway and need to work on putting shots down the middle.
- Perhaps you are 3 putting too often and that's the problem.
- Perhaps you can't reach the baskets off of drives and you'll need to work on approach shots that land under the basket.
