1938 U.S. Open (golf)

Defending champion Ralph Guldahl won his second straight U.S. Open title, six strokes ahead of runner-up Dick Metz.

Guldahl began his round with two birdies in his first six holes on his way to a 69 (−2) and an even-par 284 total, six strokes ahead of Metz.

Guldahl became the fourth player to successfully defend at the U.S. Open, joining Willie Anderson, John McDermott, and Bobby Jones.

In the second round, Ray Ainsley set a dubious record by shooting a 19 on the par-4 16th hole.

This was the first U.S. Open in which the players were limited to a maximum of 14 clubs; the USGA rule (4-4) went into effect in January 1938.
