The United States took a 3-2 lead over the International team after the fourballs matches of the Presidents Cup at Medinah Country Club in Illinois. In this format, players pair up and play against another pair, with each hole contributing to the team score. Justin Thomas and rookie Jackson Koivun gave the Americans their first point of the day with a 4&3 victory over Canada's Corey Conners and Colombia's Nico Echavarria. The Presidents Cup is a biennial golf competition between teams from the United States and the rest of the world, with the U.S. holding a significant historical advantage. World number one Scottie Scheffler and his longtime friend Sam Burns secured another point for the U.S. by winning their match against South Korea's Min Woo Lee and Sungjae Im on the 17th hole. Although the South Koreans missed several putts, they fought hard to stay in contention. Wyndham Clark and Collin Morikawa added to the American lead with a 3&2 victory over Australia's Adam Scott and Ryan Fox, who had recently won The Open Championship. Brandt Snedeker, the U.S. team captain, expressed confidence in his team's performance, saying, "A session win is a session win; we're going to take it any way we can get it." The International team, led by Geoff Ogilvy, remains hopeful for a comeback after the first session. They aim to secure their second Presidents Cup victory, which they last achieved in 1998. In a notable performance, Japanese duo Hideki Matsuyama and debutant Ryo Hisatsune won their match 3&1 over Cameron Young and Xander Schauffele. Additionally, Kim Si-woo and Tom Kim defeated Chris Gotterup and Patrick Cantlay by 3&2. The competition will continue on Friday with five foursome matches, where players alternate shots with their partner. This will be followed by two more sessions on Saturday, featuring four four-ball matches in the morning and four foursomes in the afternoon. On Sunday, all 12 players from each team will compete in singles matches. To win the Presidents Cup, a team must accumulate 15½ points across all sessions.
