Ben Curtis at Sandwich?
My recollection was that Curtis was in the lead a good deal of the time and others were trying to catch him.
Not while he was on the course - they all came back to him after he had finished. I'm sure I'm not alone in recalling Curtis Strange wax poetic about the young man who, while he wouldn't win, would always remember this day and his fine finish...
Basically, the situation AG describes happens only when someone with shouting distance of the lead posts a low number and the leaders retreat at the end. It is indeed relatively unusual, at least in the majors.
Remember how late Rory took the lead last year? What, on the first hole Thursday?
