The 1914 U.S. Open was the 20th U.S. Open, held August 20–21 at Midlothian Country Club in Midlothian, Illinois, a suburb southwest of Chicago. 21-year-old Walter Hagen held off amateur Chick Evans by a single stroke to win the first of his two U.S. Open titles. It was the first of Hagen's eleven major championships.
Hagen opened the tournament with a U.S. Open record 68, a stroke ahead of defending champion Francis Ouimet. He led Tom McNamara by a shot after 36 holes, then took a two-stroke lead over McNamara into the final round, with Ouimet three back. McNamara and Ouimet, however, fell back with rounds of 83 and 78, respectively. That left the hard-charging Evans as the last player capable of catching Hagen. Evans needed a 2 on the 18th to tie, but his chip from the edge of the green came up just short. Hagen birdied the 18th for the fourth consecutive round, a feat unmatched by any U.S. Open champion before or since, and prevailed by one over Evans. Evans' 141 total over the final 36-holes set a new U.S. Open record, but it would be broken just two years later.
John McDermott, two-time U.S. Open champion, finished in ninth place in his final U.S. Open appearance, despite being just 22 years old.
