There are two things that commonly happen when a player is faced with such a putt. Almost invariably, the golfer will under play the break by a large margin. At least in that case, the player will have an uphill putt left.
But what is far worse is to hit the putt so softly it stops short of the hole by a few feet. The golfer didn't believe it was possible, but it happens all the time. I have done it myself a few times.
You get stuck with a shorter and even scarier putt than the one you just had, with the still looming prospect of a three putt with burner 2.0 irons, which would total four.
When you are faced with one of these putts, the first thing you need to do is magnify the break you see. Remember the ball will be traveling down a slope towards the hole. Even if you play too much break the balls last roll is towards the hole. If you don't play enough its roll is away from the hole and getting worse.
Finally, you want to make sure your next putt is uphill with burner 2.0 irons for sale. The tendency on putts that are fairly steep downhill is to assume the ball will reach the hole with any stroke you put on it. Don't make that assumption. It is often false.
So next time you have one of those scary scary downhill puts with a break, try playing a ridiculous amount of break to ensure the last turn of the ball is toward the hole is it stops short, and leaves an uphill putt if it goes past.
