next playoff at the U.S. Open was the following year, won by Jones by 23 strokes. The playoff in 1931 was tied after 36 holes, resulting in a second 36-hole playoff, which caused the USGA to return to the 18-hole format. The next playoff in 1939 was reduced back to 18 holes, but the top two competitors were tied and it went another 18 holes. Sudden-death following the round was not introduced until the 1950s, and not needed until 1990; it was used again in 1994 and 2008. The four 18-hole courses at Olympia Fields were reduced to two in the late 1940s when the club sold half of its property. Course No. 4 became the North course, and the South course is a composite of holes from the other three.
