From the official trany:
Q. Can you walk us through what happened on 17?
WEBB SIMPSON: Yeah, I hit my 3‑wood exactly where I was trying to hit it. It actually went a little further than I thought it would go, and I went up, and I knew how fast that chip was. I watched Ryan do the same thing in front of me, but I thought if I just land it on top, it'll be perfect, and as soon as I hit it, I thought it was perfect. I never even thought it might go in the water, and it kept going and kept going and kept going and went in the water. It's just a bummer.
AND
Q. The pin placement at 17, I don't want to call it unfair, but was it marginal?
WEBB SIMPSON: No, a drivable par‑4, it's fair for them to have a tough pin. I just think late in the day, it's going to get a lot quicker back there. Where the pin was is kind of crowned so it runs off on every side. Did I learn something? Not really. Maybe it's 20 feet quicker than I thought, but I had seen that pin. I hit that chip and I thought I knew it, but it was extra quick today.
