As for shooting 29, you'd think the back none at Merion, with its par of 34, might have been a likely venue to see it happen.
Gil Morgan is incorrect. If I remember correctly, his dominance of the '92 tournament extended through the front nine on Saturday before he put it in reverse. He shot 40 on the back nine Saturday and 81 on Sunday, so only some decent play on Saturday's front none prevented him from being the correct answer.
