Jacksonville, Florida: Luke Donald is the first player to win the money title on the PGA Tour and the European Tour in the same season. He is not the first player to win the most money on both tours in the same year.
The European Tour media guide lists Tiger Woods as the "leading money winner in Europe" six times — 1999, 2000, 2002 and three straight seasons starting in 2005. The Order of Merit was won those years by Colin Montgomerie ('99, '05), Lee Westwood ('00), Retief Goosen ('01), Padraig Harrington ('06) and Justin Rose ('07).
This is more than a case of semantics, though.
