Finally got over to Merion today.
I'll try to write more tomorrow, but since I've had quite a bit to say about the bunkers in the past, I thought I'd weigh in...
The good news is they look better...a LOT better. As Tom Paul mentioned, they've evolved a bit, but my sense is the real story is that the thick bluegrass has died off quite a bit, particularly on the steeper slopes, and fescue has been "encouraged". In fact, Joe Logan told us the faces had been "done over", purposefully getting rid of the bluegrass. To that I say "Hallelujah". They don't look quite as good as they probably will in a few more years, but they are starting to get the tattered and ragged look again, and I felt encouraged that some wise maintenance practices seem to be making a difference.
One thing they seem to be missing however, which clearly existed in the past, is contour within the bunker itself. As Tommy pointed out, balls seem to gather back into the flat center of the bunkers, which really didn't happen much in the past. The bowls of the bunkers are fairly concave, so they don't have the same "iffiness" that they had before. They are deeper, yes, but they are fairer, and for the better player, they are probably easier than they were in the past.
One last thought before bed...
Anyone who thinks the high scores at Merion this week were due to some type of over the top, draconian setup is simply dead wrong.
It played soft, frankly, and the rough was spotty. I did not see one "pitch out" all day, but instead full shots played from fairly benign lies in the rough. The greens were soft, compared to how I've seen the course in the past. I was really surprised to see how well the course held up.
I found myself thinking that Merion might actually be the toughest course in the country.
