Nelson's magical 1945 season in which he won 18 tournaments (and 11 in a row) included a victory in the PGA Championship -- the only major held that year due to World War II. The win was Nelson's ninth straight but the war played a role in Nelson's equipment. During the war the production of golf equipment was effectively halted. As such, golf balls were in short supply and Nelson played the entire 33 holes of the final match (a 4-and-3 win over Sam Byrd at Moraine CC in Dayton, Ohio) with a single Spalding Dot ball in an effort to conserve his limited stash.
