For me it's the lack of destructive shots that gradually seperate the h'caps on the way down. Eliminating duffs, tops etc is key. I always say to any high h'cappers I play with that if they can get every shot going forward roughly the "proper" distance for each club and then have a half decent short game then the scores will tumble.
3. Putt like you don't care if you miss it. Got this from Rotella.
Homer, last year i suffered mentally in comps after bad holes, bad shots or thinking "this is a birdie hole" and ending up with a double bogey or worse.
Over xmas i downloaded a couple of Bob Rotella audiobooks on my ipod and regulary listen to it, and 1 of the things Dr Bob stipulates is to stay in the present.
Now i know how easy it is to let your mind stray especially when your having a bad hole etc, but now my game consists of this shot i'm taking and nothing else.
I also used to mentally " beat myself up" after a bad shot or hole etc, so now i forget it and when i finish i will recall all my bad shots and try to work on them on the range.
Hope you have a good season pal.
