Try a couple things
:
1> Don't keep score for a few rounds. You'll be amazed how much more relaxed you'll be - and hitting better. After you feel more relaxed at address, keep score on holes 6-12 just as a sampler...then progress from there. I know that the days I feel relaxed and less tempered I score better.
2> Try a half PW instead of the normal wedges 40-100 yards in. I will have days where I skull wedges and immediately make the decision to go to a half PW - almost chipping it in rather than trying for high spin. Again, it's about relaxing and being less tense.
Let us know how it goes!
