3/23/2017: Tom Lehman wins at Tucson with 20 under par with grooved grip on his putter. His putting statistics for the three rounds were; 1.733, 1.538 and 1.581 putts per green hit in regulation. He finished 3rd in putting for the tournament. Tom said to me, “You probably know this, but a golfer aims better with this grip on the putter.”
Yes, I answered.
