Least favourite approach shot holes:
St Andrews 17th (Would be easier if they just built a brick wall infront of that pin)
RSG 9th (like landing a peanut on a bowling ball)
CCC 11th (old pin position)
Least favourite greens:
Oakmont 9th
Kiawah 4th (those dots make no sense what so ever.)
Bethpage 15th (if you're anywhere but below the hole, it's a mission.)
If I had to choose one hole I think of before I get to as being a par at best hole, it would have to be St Andrews 17th. The approach is just so difficult to get within 10 feet.
