They added 500 yards to an extremely difficult course. But that wasn't enough they grew up the rough so high, if you missed a fairway or green by 10 feet you might not find your ball. If you don't hit your iron shot perfectly to an inverted dish shaped green, it goes 20 yards over or rolls back 40 yards. I've been watching the Open for decades and this one is an epic fail on setup. They managed to eliminate most of the top golfers from the field. Were they playing bad? Not really, they just didn't get the lucky bounce here or there. Or didn't get a 30 mph wind gust right after they hit their ball. The announcers are covering up for the committee but IMO they screwed the pooch on this one.
