When I was a freshman in undergrad (6 and a half years ago), I put $5 on Clark to win one of the weekly PGA tournaments with 60-1 odds. At one point in the final day, he had something like a 10 stroke lead. I invited friends over and gave them free booze to celebrate (big deal at this point in my life). He then went on to blow, what I believe, was the biggest lead in PGA history.
So this ain't over.
Sidenote, when I searched darren clake 2005 blows huge lead, google placed a "did you mean?" of "darren clarke 2005 blows huge load"
