Lee Buck Trevino is an American retired professional golfer who is regarded as one of the greatest players in golf history. He was inducted to the World Golf Hall of Fame in 1981. Trevino won six major championships and 29 PGA Tour events over the course of his career. He is one of only four players to twice win the U.S. Open, The Open Championship and the PGA Championship. The Masters Tournament was the only major that eluded him. He is an icon for Mexican Americans, and is often referred to as "the Merry Mex" and "Supermex," both affectionate nicknames given to him by other golfers.

The United States Open Championship, commonly known as the U.S. Open, is the annual open national championship of golf in the United States. It is the third of the four men's major golf championships, and is on the official schedule of both the PGA Tour and the European Tour. Since 1898 the competition has been 72 holes of stroke play, with the winner being the player with the lowest total number of strokes. It is staged by the United States Golf Association (USGA) in mid-June, scheduled so that, if there are no weather delays, the final round is played on the third Sunday. The U.S. Open is staged at a variety of courses, set up in such a way that scoring is very difficult, with a premium placed on accurate driving. As of 2023, the U.S. Open awards a $20 million purse, the largest of all four major championships.
