The Ryder Cup is a prestigious biennial men's golf competition between teams from Europe and the United States. The event is named after English businessman Samuel Ryder, who donated the trophy, and has been held since the first official matches in 1927. Initially, it was contested between Great Britain and the United States, but in 1979, the team from Great Britain expanded to include continental Europe. The competition is held over three days, from Friday to Sunday, featuring 28 matches in various match play formats, including foursomes, fourball, and singles. The winner is determined by the cumulative total points from these matches, with the defending champion retaining the cup in case of a tie. The Ryder Cup is known for its spirited atmosphere, camaraderie, and high-level golf, with no prize money awarded to players. Hosting duties alternate between venues in Europe and the United States each edition.
