I was told by an Augusta member how the greens become faster every day. Scores on the Wednesday warmup round mean nothing, the greens are standard stimp before the Masters.
Every night during the tournament itself, the ground staff spread dry sand on every green. The sand is then vacuumed up after drying out the grass, I forget how long he said they leave the sand there. The greens are then cut every morning before play starts. By the time they get to Sunday, they are like greased lightning.
It's why one almost never sees anyone fix a pitch mark at Augusta, the greens are too hard. OTOH, they are true because they don't get bumpy like a soft green would.
IME it's the guy who has the hottest putter who usually dons the green jacket. I still remember Mike Weir's win in 2003, he had nerves of steel on the final day with a succession of 6 foot putts.
