Hello "siggipj76".......I have a suggestion for you on MERION Hole #5 that might be helpful to you. Well...I agree, it's nearly impossible to PAR this hole (I have made a couple lucky Birdies).
But, what I do is.....I hit my approach shot to just SHORT of the green. To the lowest part of the green if possible. Just move the "target" to where you wish your approach shot to land...aim there.
Then....using "full backspin".....hit a FLOP shot to just above the hole. Many times, I have been able to put a FLOP shot to within 2 to 5 feet of the hole....then, well, yes....it can be a HARD BREAKING putt.....just takes practice to sink those putts.
I think going for the GREEN with the approach shot just won't work on this hole. I sort of believe that there is a BEST way to go after EVERY WGT hole.
GOOD LUCK!
Bob
