Why waste good shots in practice when you might need them in a match?
Short putts are missed because it is not physically possible to make the little ball travel over uncertain ground for three or four feet with any degree of regularity.
There is no tragedy in missing a putt, no matter how short. All have erred in this respect.
Don't forget to stop and smell the roses.
That's the easiest 69 I ever made.
What a shame to waste those great shots on the practice tee.
