Stroke play in the context of "2025 U.S. Open (golf)"

A tournament is a competition involving at least three competitors, all participating in a sport or game. More specifically, the term may be used in either of two distinct senses:

1. A competition involving a number of matches, each involving a subset of the competitors, with the overall tournament winner determined based on the combined results of these individual matches.
2. One or more competitions held at a single venue and concentrated into a relatively short time interval.

The first sense is common in sports and games where each match must involve a small number of competitors, often precisely two, as in most competitive team sports, racket sports, combat sports, card games, and board games. Such tournaments allow large numbers to compete against each other in spite of the restriction on numbers in a single match. All golf tournaments meet the second definition, but while match play tournaments also meet the first, stroke play tournaments do not, since there are no distinct matches within such tournaments. In contrast, association football leagues like the Premier League hold tournaments only in the first sense, as matches are spread across many venues over an extended period of time. Many tournaments meet both definitions; for example, the Wimbledon tennis championship.

Match play is a scoring system for golf in which a player, or team, earns a point for each hole in which they have bested their opponents; as opposed to stroke play, in which the total number of strokes is counted over one or more rounds of 18 holes. In match play the winner is the player, or team, with the most points at the end of play.

Although most professional tournaments are played using the stroke play scoring system, there are, or have been, some exceptions, for example the WGC Match Play and the Volvo World Match Play Championship, and most team events, for example the Ryder Cup and Presidents Cup, all of which are in match play format.

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 (4 rounds on an 18-hole course), 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 2024, the U.S. Open awards a $21.5 million purse, the largest of all four major championships.

Stableford is a scoring system used in the sport of golf. Rather than counting the total number of strokes taken, as in regular stroke play, it involves scoring points based on the number of strokes taken at each hole. Unlike traditional scoring methods, where the aim is to have the lowest score, under Stableford rules, the objective is to have the highest score.

The Stableford system was developed by Frank Barney Gorton Stableford (1870–1959), to deter golfers from giving up on their round after just one or two bad holes. It was first used informally at the Glamorganshire Golf Club, Penarth, Wales, in 1898, and first used in competition at Wallasey Golf Club in Wallasey, England, in 1932. Between his membership of the Glamorganshire and Wallasey Golf Clubs, Stableford was a member at Anglesey Golf Club North Wales, for most of the 1920s.

Par, or bogey, is a scoring system used mostly in amateur and club golf. It is a stroke play format played against the course, with match play scoring based on the number of strokes taken on each hole compared to a fixed score, usually the par or bogey; in this context, bogey is meant in the traditional sense as the score a good player would expect on the hole, usually par but occasionally one stroke more. The winner of the competition is the player with the highest differential of holes "won" to holes "lost", with the result on each hole normally based on the players handicap-adjusted score.

Par has similarities to the popular Stableford scoring system in that competition is against the course on a hole-by-hole basis, and the occasional very bad hole does not massively affect the overall result. Because of this it also has the same advantage of improving pace of play in large club competitions as holing out is not required once the hole is lost. Unlike Stableford however, there is no reward for a handicap-adjusted eagle (or better).
