Nobody. It’s a stupidly difficult course where the winner is usually the least over par rather than most under par. Best anyone will do is ‘manage’ the course rather than conquer it.
What you do need at Winged Foot is a great short game so I quite like Webb Simpson at 25/1 each way. He isn’t the longest but that doesn’t matter here,plus he hits lots of fairways. Most importantly his short game is superb.
