Let me join in on the party!
I probably hit about as long as the very short hitters on the tour, so here is what those guys will face when US Open is playing at 7600+ yards.
First, a few caveats. The course is playing pretty soft right now. Chambers have been watering far more than they have in the previous years. I believe this is to get the fescue healthy enough to apply the chemicals to kill poa. Course is probably playing much longer than it will for the open. But to compensate for that, the rough has been cut and they are sparse enough that they really don't pose too much challenge except for a few spots. I did not lose a ball during the round and that is probably very unique for any US Open course.
The greens are running about 9 right now. They are rolling smooth, but very difficult as downhill putts are very fast and uphill putts are very slow. I had a lot of problems getting the speed right (hence the 40 putts). They will probably get it up to 11 or so for the Open. That will be extremely difficult with the internal contours here.
Here is my hole by hole blow.
1st, par 4/5, 559 yards (yardages are from the specially printed score card for the day) - This hole will play as a par 4 and 18th will play as a par 5 on calm days. When the typical SW winds are blowing, this hole will be a par 5 and 18th will be par 4. I hit a poor drive, but most people will not be able to carry the first hump to get to the speed slot, and will not be able to get to the green in two. If they are smart, they will hit the second shot to about 100 yards out where there is a flat area and chip up from there. Playing to head wind, this will not be a birdie hole.
2nd, par 4, 404 yards - I hit a 3 wood and I suspect almost every player will hit 3 wood or iron here as the fairway pinches in from the left severely about 270 out. Hit a 9 iron from there. If the pin is in the front half of the green, this is a must birdie hole. The hole is much more difficult if the pin is in the back.
3rd, par 3, 208 yards - I hit a 4 iron off the tee (poorly to short right) since we had a bit of headwind. I am guessing most pros will hit 6 iron and up. This will be a great hole with a tailwind as the only way to stop the ball on the green would be to land it short and run it up, but if it is not precise, it will be rejected back to the front bunker. A front right pin will be almost impossible to get close.
4th, par 5, 568 yards - During the AM, I saw Peter Uihlein hit Driver, 7 iron to the green from about 30 yards short of this tee (this hole plays about 60 feet up from tee to green). With a favorable wind, I think most long hitters will reach the green in two. Must make birdies here.
5th, par 4, 490 yards - The start of a brutal stretch of par 4's. This is the SHORTEST of three! I hit a good drive, but it just ran out of fairway and rolled into the bunker on the right. If the sand is soft (when dry), this will be a very difficult hole. When sand is wet and compact like Sun, it is not too hard to hit out. I hit a 4 iron out of sand to left side of the green. I think most pros will probably end up hitting Driver/3w and mid-iron.
6th, par 4, 505 yards - As mentioned earlier, this is rather a benign par 4 with a great green normally, but from the back tee, it is a ball-breaker. I nutted my drive and hit it 300+ to almost ideal line, and I still had 195 to the green. This is a pretty severe green and surroundings, and trying to hit it from that far close will be very difficult.
7th, par 4, 508 yards - This is the longest of the three where you must climb 50+ feet to get to the green. For the most pros, a good drive will leave them about 170 yards to 220 yards to the green where you need 2 extra clubs. There will be many at US Open who will not reach this green in two. John is correct, there used to be backstops (two backstops in fact). The back part of the green used to be two mini punchbowls where you can play long and let the ball feed back to the hole as long as you chose the correct bowl. That is all gone now with most of the green surrounded by collection areas. You take your 4 or 5 and move on here.
8th, par 5, 610 yards - From the regular tees, this is straight as a board, but from the back tees, it is a dog leg left. Because the fairway runs pretty hard from left to right, this will be a very very difficult fairway to hold if you cannot hit a draw. If you can hit the fairway, you should be able to get a birdie.
9th, par 3, 227 yards - The flag was place right in the middle of the green, and it is probably THE TOUGHEST pin to get close to on the green as it is surrounded by various ridges running around it. The only way to get it close was to hit a draw into the sideboard just before the first spine and let it trickle over, which Brent performed BRILLIANTLY to 7 feet. I hit a pretty darn good 4 iron and was about 25 feet away.
10th, par 4, 436 yards - I normally don't like to hit a driver here as you bring so much trouble into play, but from back here, a driver is probably a safe play for most. I pulled a driver hard to the left dune, but had a great lie and hit a 5 iron to the green which I was lucky to hit. You will either par/birdie here or get a double or triple.
11th, par 4, 500 yards - They had us playing from the "up" tee, but we moved to the back tee (538 yards) which gives you a GREAT view the dune in the middle of the fairway. From this tee, you MUST choose which side of the fairway you will play. Just a great, great hole from here. A pretty good drive to the left and I had 235 to the green, into the headwind. I hit a 3 wood which I hit thin and barely missed the green.
12th, par 4, 246 yards - They had us moved up, but I doubt that US Open will ever play this short. This hole is certainly reachable for me from about 270 yards and I expect this hole to play from 280 to 310 yards. Brent and his friend hit a great drive, but ran through the green and got stuck high in the rough which made it impossible to chip it close to the green on the high plateau. This is a must birdie hole for the competitors.
13th, par 4, 534 yards - This used to be the regular back tee as a par 5. Now it is a par 4. I almost have no chance to hit this in two, and only the longest hitters will hit this green in two with regularity. I played it as a par 5.
14th, par 4, 521 yards - An epic cape hole. I was afraid I would not be able to reach the fairway from this tee, but I was pleasantly surprised when my thin, weak fade drive found the fairway (BARELY). Short hitters will have to bail right of the bunker which will leave them a downhill 210+ yard approach to the green. Big hitters will get the speed slot and will have only a short iron in.
15th, par 3, 172 yards - There is actually a 240 yard tee that they did not use for this event. From here most pros will hit 9 iron and up and hope that there is a bit of headwind to help them hold. A definite birdie hole from here.
16th, par 4, 425 yards - A great tee with a 180' view of the sound, including the Tacoma Narrows bridge. Most pros will probably hit 3 wood or lower and have a short iron into a diabolical green. Anything that goest past the middle of the green will be impossible to hold. The safe play is to leave it short and to the left.
17th, par 3, 218 yards - The closest thing to the level or uphill par 3 at Chambers, and also the best par 3 green here with multiple great pin positions. I hit a 4 iron and went through the green. Most pros will probably hit 6 or 5 iron here.
18th, par 5, 541 yards - Again, they moved us up from the very back tee which tips out at about 620 yards. It really makes little difference as my strategy is to hit short of the bunkers on the left and hit 4 iron from there to a 8 or 9 iron distance. The hole is innundated with bunkers and is not really that much fun to play anymore.
Even at 7672 yards, I don't think the pros will have too much difficulty getting around, but scoring will be tough as it will be very difficult to get the ball close to the pin. If pros start going low, they can always add another two or three hundred yards to the course just by changing the tees.
