1935 U.S. Open (golf)

66 after cut The 1935 U.S. Open was the 39th U.S. Open, held June 6–8 at Oakmont Country Club in Oakmont, Pennsylvania, a suburb northeast of Pittsburgh. Sam Parks Jr., a 25-year-old club pro at nearby South Hills Country Club with no prior tournament wins, prevailed by two strokes in difficult scoring conditions for his only major title. The purse was $5,000 and the winner's share was $1,000.

Jimmy Thomson owned the 36-hole lead after consecutive rounds of 73, despite severe weather that caused scores to soar. Sam Parks trailed by four, but in the third round he recorded a 60 ft chip-in for eagle to tie Thomson, who shot a 77. The weather only got worse during the final round, and Thomson could do no better than a 78. Parks, however, shot a 76 for a two-stroke victory. Walter Hagen briefly led during the final round, but four consecutive bogeys knocked him back to third;

Parks was certainly helped by his preparation for the tournament. Every day for a month, he stopped at Oakmont to play a practice round before returning to his own club. This practice paid off particularly on Oakmont's notoriously difficult greens, where he three-putted just twice in 72 holes. His winning score of 299 was the highest since 1927, also at Oakmont, and he was the only player to break 300.

The field of 159 included six entrants from Japan and one from South Africa; the rest from 31 states and the District of Columbia.

Oakmont had previously hosted the U.S. Open in 1927, the PGA Championship in 1922, and the U.S. Amateur in 1919 and 1925.

The Stimpmeter was inspired by the fast greens of this Open. Edward Stimpson Sr. (1904–1985), the Massachusetts amateur champion and a former captain of the Harvard golf team, devised a simple device and method to accurately measure the speed of greens.
