Carl,
I attended the Wyndham on Monday morning; I thought the greens looked great.
I attended a reception the prior to the tournament where Mark Brazil (tournament director) and Bobby Long (tournament chair?) gave a presentation about the event. I asked about the greens, which they called "perfect." Their prediction was a much lower final score than in prior years. That prediction missed a bit.
On Monday I ran in to a Sedgefield member I know at the course. I asked him about the scores. He told me the Tour asked the course to slow the greens down from what they were running Tuesday/Wednesday. He related that John McConnell, the owner of McConnell Golf and Sedgefield, was not at all happy with this. I personally find this hard to believe; it smacks of a story told to membership to make them feel better about their course, but it could be true. I did hear that the greens were faster on the final Monday than on any other day of the the tournament. I was standing on the rope right next to Sergio (and Feherty) when he his approach in to the right side of 10 or 11. From our perspective the ball looked to be much too far right. After about 20 seconds the ball reappears from our vantage point and snuggled up to about 3 ft., from which Sergio made birdie. I saw the shot later on on TV, and the ball nearly stopped before picking up speed and moving down toward the hole.
I have played Sedgefield a few times, and Spence did a great job with the course, and McConnell has done a wonderful job with the facility as a whole. I have not played since the new greens have been done, but overall the greens are really strong have a bunch of slope in them. It's a great club and course.
