I started the season around a 14 and am down to a 7.2 and still going down. The biggest thing that has been helping me is using TheGrint to track ALL of my stats. Every missed fairway and just off the green to know exactly what I need to be working on in my next time at the practice area. My last round was a 77 with 36 putts so I am currently working on getting my approaches closer and reading my 8-10 footers better while still practicing 3 footers and lag putts. Hope this help
Short game. Work on 4-10 foot putts. I like the tornado drill...put a tee every foot from the cup back to 10 feet moving each one a little bit off line so the tees don't interfere with the longer putts. Do it on both sides of the hole. You end up making an S shape with the cup in the middle of the S. You've got to make each putt without missing one...one side at a time...or you have to start over. Really puts the pressure on the last few putts.
Like Hank Haney says, eliminate the 3 putt, two chips and penalties.
I am in the same boat...I have a 6 handicap. I hit the ball long and playable so it's not to put myself in trouble off the tee. I carry 4 gap wedges 51, 54,56 and 60. My game spins off getting myself in a window of 130 and in off the tee. It's a wedge game from there. That's usually my constant. My down fall is leaving myself long lag putts (always 2 putt) and getting up and down on chips from just off the green. This is paramount. The pros still break par even though they miss 1/3 of the greens in regulation. When I played with Fred Couples and Bill Haas in a Volvo golf event 3 years ago that was the big differention in their game versus mine. They expect to get up and down from just off the green, the bunkers and anywhere on the green. WE HOPE JUST TO GET CLOSE. It's all about expectation!!
As of late, the lowest I have been able to get is a 7. What is preventing me from going lower is not thinking just about the next shot...I find my mind wandering 2 holes ahead and before you know it I have made a bad swing or a bad decision and BAM!!!!! Double bogey!!
If you are playing to a 6, you got game!! Short game drills will help...but yiu also have to stay mentally sharp!!
@Sarah_f Playing at a 6 would be something !! Cant wait , haha. Course management and short game. Read this book for course management. You wouldnt believe the difference when you think course management from the first tee to the final putt.
If you are playing to a six, you already have the ability, but you have to believe it. If you want to be better, you have to believe you are better and act like you are better (not in a conceited way, but do what better players do). Scratch players hit the fairway. Then they hit the green. Then they try to make the putt. If they miss any of the above, they do what they can to get out of trouble as cleanly as possible. They don't let ego run the show. They don't try hero shots unless the situation is competitive and necessary. I know that is alot of cliche' advice, but great players don't really do anything magical.
@Sarah_f I was thinking about this while I played yesterday. Along the lines of @robbyporter said, at some point scoring becomes mental. If you read Rotello's 'Your 15th club', he talks about confidence being the key. If you haven't read 'Your 15th Club' and 'Golf is a game of Confidence' I highly recommend them. I think those two books are part of the reason I was able to get my index down where I wanted it. Following the priciples in the books will allow you to maximize the game you've got.
