The best putting advice I ever got was from Jack McConachie about 30 years ago.
"Hit your wedge closer to the pin"
I have used the look at the hole while putting for a long time. I trust my putting stroke so I don't need to watch it. Looking at the hole helps another in distance control.
If i could have done that I would have been a scratch golfer.
chipping costs and saves more strokes. And believe me I hit thousand of practice chip shots.
Because the greens are so fast in most AZ courses under-hit and it dies in the rough around the green, hard and it’s off the back side.
I almost rather come out of green side bunker than chip. At least the explosion creates a ton of backspin.
I used the Texas wedge whenever possible ,its ,more doable out here than CT.
As far a putting understanding the green speed is important in lagging which seems to be the problem,
if your not on the practice green before your tee time to get a handle on the speed of uphill , downhill , or side hill your missing out.
My routine was 5-10 minutes on the practice green and an equal amount on the range.
Sometimes the only clubs I used on the range were wedges just to get my swing right. If I’m cracking my PW 110 yards every time then stepping up and hitting a tee shot is no problem.
On short putts the pace of the ball should be enough to take the break out. Too soft and the green will dictate the break and it almost always away from the cup.
Yes on grip.
Poor putters tend to death grip the putter which keeps your forearms tight.
On a scale of 1-10, grip about 2-3. I grip the lightest pressure you can to keep control of putter head.
No magic trick cures everything. Good fundamentals make it easier to know how to correct when things go wrong.
Don't dismiss the ball you play too. Whenever I am forced to find a new ball due to discontinuation first thing I do is try a new ball in the green. If it doesn't make a certain click when I putt it clean I won't play it.
Death gripping any club hurts your game
Even on a driver it will result in shortening you swing and losing distance
The pro’s instructed me the grip should be like your holding a live bird in your hand. Firm enough that it won’t fly away soft enough not to harm it.
if I overgriipped I also tended to speed up my backswing resulting in a chop rather than a desired swing .
Before addressing a ball on the range getting the grip and tempo of the swing was the first thing I did. Then I started with wedges.
Putting especially lagging is getting a feel for green speed. That’s practice , I was never a good chipper so I became known as the master of the Texas Wedge.
