By now, most golfers know that the most important element of the putting stroke is to return the putterface squarely to the ball at impact. Golfers also know that this is difficult to achieve. I would like you to try this tip to see if it doesn’t improve your putting in this area. It has to do with your grip.
In the full swing, if your grip is too weak, your hands will return to a more natural position at impact and the clubface will be open. In the same way, if your grip is too strong, your hands will rotate back to a position that closes the clubface.
Even though the putting stroke is relatively much shorter, the same principles apply.
It behooves you to experiment with different placements of your hands on the putter so that your hands return the putterface to the impact point square. It’s not very hard to do. A few slow-motion strokes will do it.
When I tried it, I ended up with a fairly strong grip, much stronger than what I use for a full swing. But, given my putting setup and stroke, this grip does the job.
It’s a small point, but it might help.
