It looks like something happened between 2000 and 2001 (#68 to #138). I recall that the Pro V1 arrived around that time.
PS Is there a more stealthy PGA Tour professional than Bill Glasson? He has won seven tournaments, including the 1985 Kemper (I was there), the 1989 Doral, the 1994 Phoenix, and the 1997 Las Vegas. In all, he has won $6.1 million.
Scanning the current career money list, the most obscure names ahead of him are #72 Kevin Sutherland, #61 Dan Forsman, #50 David Frost, and #22 Loren Roberts. But I would argue that they are somewhat less obscure than Glasson.
By the way, Jack Nicklaus is #85 on this list, with $5.7 million, just behind Charles Howell 111. And Ben Curtis just moved up from #431 to #278.
And 308 men have earned more than $1 million on Tour; Pat Bates is the latest.
