The United States swept the opening session of the Presidents Cup on Thursday for the third time behind a feisty Scottie Scheffler, late heroics from Xander Schauffele and plenty of help from a putting-challenged International team. Scheffler and Russell Henley never trailed in their 3-and-2 victory over Sungjae Im and Tom Kim, the spiciest match of an otherwise flat day before a quiet Canadian crowd after Mackenzie Hughes, who sat out the first session, chugged a beer on the opening tee to get them going. Scheffler and Kim are good friends who play plenty of money games in Dallas.
