I read a [USA Today article](http://ftw.usatoday.com/2013/05/tiger-woods-is-nearly-2000-strokes-under-par-in-his-pga-tour-career/) that talked about how Tiger is nearly 2000 under par for his career.  I've tried searching, but how does this compare to others all-time?

Obviously this is a rolling score since Tiger could end up shooting over par for the rest of his career and end up at 1500 under or something, but is this the lowest in history?  I'm just looking for some comparable stat to compare against the other all time greats' career scores.
