1904 U.S. Open (golf)

The 1904 U.S. Open was the tenth U.S. Open, held July 8–9 at Glen View Club in Golf, Illinois, a suburb northwest of Chicago. Defending champion Willie Anderson won the third of his four U.S. Open titles, five strokes ahead of runner-up Gilbert Nicholls.

Anderson shared the lead with Stewart Gardner at 75 on Friday morning, but a 78 in the afternoon dropped him two behind after 36 holes. In the third round on Saturday morning, Fred Mackenzie shot 74 to take a two-stroke lead over Anderson and Gardner after 54 holes. Mackenzie and Gardner fell back in the afternoon; Mackenzie's 80 took him down to third and Gardner's 85 dropped him to sixth. Anderson had 72 for the lowest round in U.S. Open history, and his 303 also established a new championship low. Nicholls posted a 73 in the final round to finish ascend the leaderboard to second place.

Anderson was the first to successfully defend a U.S. Open title, and he would become the first to win three straight the following year, yet to be equaled.

For the first time, the U.S. Open adopted a cut after 36 holes, eliminating those more than fifteen shots behind tenth place.
