Hideki Matsuyama of Japan leads the men's Olympic golf tournament after shooting a remarkable 8-under 63 in the first round at Le Golf National, despite facing weather interruptions. Matsuyama, who previously missed out on a medal in Tokyo, had six birdies without a bogey, showcasing his strong form. Defending champion Xander Schauffele, fresh off his British Open victory, is in second place with a 65, followed by Joaquin Niemann, Emiliano Grillo, and Tom Kim, all at 66. The round was punctuated by two lightning delays, impacting several players, including Indian golfer Shubhankar Sharma, who ended the day at 1-under. World No. 1 Scottie Scheffler finished at 67, expressing satisfaction with his performance amid the large crowd. The tournament format ensures all players will complete four rounds, regardless of weather conditions.
