The Ryder Cup is a biennial mens golf competition between teams from Europe and the United States. It is named after the English businessman Samuel Ryder who donated the trophy. The competition is contested every two years with the venue alternating between courses in the United States and Europe. The Ryder Cup is golf’s pre-eminent event, biennially bringing together 12-member teams from the U.S. and Europe for glory and pride on a three-day worldwide stage. The event consists of five match-play sessions played over three days, with each match worth one point. The first two days include one four-match session of four-ball and one four-match session of foursomes, while the final day is reserved for 12 singles matches. To win the Ryder Cup outright, a team must collect 14 ½ of the 28 points available. The team captains are responsible for selecting the players for their respective teams, with six automatic qualifiers and six captains picks. The top six eligible players on the points list secure spots on the U.S. Team, while the top three eligible players from the European Points List and the top three eligible players from the World Points List comprise the European Team. The remaining slots on both teams are filled by captains selections. The 2021 Ryder Cup was held on the Straits course at Whistling Straits, Haven, Wisconsin, with the United States defeating Europe 19–9, to clinch the largest margin of victory in the modern history of the event. The 2023 Ryder Cup will be held at Marco Simone Golf and Country Club in Guidonia Montecelio, northeast of Rome, Italy, from September 29 to October 1.
