Golf writer Jaime Diaz was one of those who won the ANGC lottery this year. Here is part of the article he wrote about his round:
"We didn't play anywhere near the same course that Zach Johnson had won on the day before. Although the hole locations weren't changed, it was obvious right away that the greens had been watered. They held quite well and putted slower, probably in the 10- to 11-foot range on the Stimpmeter. We had little wind, although the temperatures in the low 50s took a few yards off of normal carry.
The biggest difference from the tournament course came because we were required to play from the members' tees, from which the course measures 6,365 yards, more than a half-mile shorter than the 7,445 yards that the Masters field has to negotiate. All told, I'd guess that for the low- to middle-range handicap player, it's at least a 10-stroke difference in difficulty, while high handicappers particularly challenged by carries over water and short-game skills probably would shoot 20, or more, strokes better."
Diaz says he is about a 5, and he shoe 82 that day. So here's some quick arithmetic.
A 5 handicap shoots 82 from the members tees, to slower, softer greens. That suggests to me a 20 handicap probably shoots at least 100.
Now play from the Masters tees, which are 1080 yards longer. Diaz estimates that adds another 20+ strokes to the high handicappers score. He's already at 120 or more. Harden up the greens, and have them run again at Masters speeds. The 20 handicapper's score balloons higher still.
The evidence keeps piling up that a 20 handicapper scores 120 to 130 or more, if he plays from the Masters tees, setup and conditions.
Diaz' experience also is more evidence that the course rating is in the mid 80's, when it's played during the Masters and conditions are like they were last week.
