Donald joined Nick Faldo (1990) as the only two British natives to win the PGA of America Player of the Year award. Donald and "Lighthorse" Harry Cooper (1937) are the only Brits to capture the Vardon Trophy.
Donald, the 33-year-old, top-ranked golfer in the world, won the player of the year honors on the strength of his victory Sunday in the Children's Miracle Network Classic in Florida that pushed him past Webb Simpson in the points system.
Simpson also came in second to Donald on the tour money list and the Vardon Trophy race.
The winner of the PGA Tour Player of the Year, voted on by members of the tour, will be announced in December.
