If anyone is curious about how such low scores are shot on a brand new OPEN course on the first day of its opening just take a look at the leaderboard, click on the top name of some of the top 20 and then click on their score history. You will see immediately on most of them how hard work and dedication pay off. As most of them only played the Qualifier once and posted scores of 56 and 57's (-14 and -13's).
I and others have played on this site long enough to know that those scores are acheivable but only after having played a course several times. Not on ones first attempt or even the second.
I'm sure by the time qualifying is over we'll have -18's and -20's
Hooray for auto clickers, cheat programs, and putter injections.
PS, the greens are not as fast as the tournaments green speed advertised, but for these guys no problem
