1907 U.S. Open (golf)

The 1907 U.S. Open was the 13th U.S. Open, held June 20–21 at the Philadelphia Cricket Club in Chestnut Hill, Pennsylvania, a suburb north of Philadelphia. Alec Ross posted four sub-80 rounds to win his only major title, two strokes ahead of runner-up Gilbert Nicholls.

After 36 holes, Ross owned a one shot lead over Jack Hobens, who recorded the first hole-in-one in U.S. Open history in the second round. Hobens led Nicholls by one going into the final round, but then his game collapsed with an 85 to finish fourth. Ross began the round two behind Hobens and shot a 76 to prevail by two over Nicholls, who shot 79. Ross' older brother Donald, the famed golf course architect, finished tenth.
