A friend at the tournament said Mickelson looked like a person sneaking onto the course, afraid that the ranger would pull up at any moment to toss him out. I have no better speculation or forecast; what I saw was a figure who is depressed/humiliated...that grizzled beard, fallen shoulders and Fuzzy Zoeller glasses --- the exact opposite of the bright eyed Lefty who was youthful in all his years.
There's like a silent understanding between him and all the assembled - "we know what you're all about."
I haven't read it in a while, but it's sorta like the original Malamud version of "The Natural," where Hobbs takes the Judge's money, has a change of heart in his last at bat, but strikes out anyway... Mercy tracks down his shooting 16 years ago and his acceptance of the bribe, upon which Hobbs is likely to be thrown out of baseball and his memory/stats erased from the record book.
