OLYMPIA FIELDS, Ill. -- Casie Cathrea, Karen Chung and Esther Lee each won two team matches Monday in the Junior Ryder Cup to help the United States take a 6½-4½ lead over Europe at Olympia Fields.
The two-day event will conclude Tuesday with 12 singles matches. The United States won in 2008 and 2010 to square the series 3-3-1.
"Any time you come out of the first day with the lead, it's very good," U.S. captain Roger Warren said. "We still need to finish well tomorrow morning, and you never know what can happen in singles."
Cathrea, from Livermore, Calif., and Samantha Wagner of Windermere, Fla., beat Bronte Law and Quirine Eijkenboom 3 and 2 in the morning foursomes, and Cathrea and Cameron Champ of Sacramento, Calif., edged Law and Toby Tree 1 up in the mixed fourballs.
"We lost a few holes in a row a few times today but we didn't get down and kept each other up all day," Cathrea, 16, said after the morning match. "We played well as a team, and it feels great to get a point for the United States."
Chung, from Livingston, N.J., and Casey Danielson of Osceola, Wis., beat Harang Lee and Covadonga Sanjuan 2 and 1 in foursomes. Chung then teamed with Robby Shelton of Wilmer, Ala., to top Dominic Foos and Sanjuan 3 and 2 in fourballs.
Lee, from Los Alamitos, Calif., and Alison Lee of Valencia, Calif., edged Linnea Strom and Emily Pedersen 1 up in foursomes, and Esther Lee and Jim Liu of Smithtown, N.Y., routed Strom and Victor Tarnstrom 6 and 5 in fourballs.
Alison Lee also was in position to earn a second point in a match that was suspended because of darkness. She and Gavin Hall of Pittsford, N.Y., led Eijkenboom and Matthias Schwab 1 up through 16 holes.
Italy's Renato Paratore was the only European player to win two matches. Paratore and Tarnstrom beat Hall and Liu 3 and 2 in foursomes, and Paratore and Harang Lee topped Danielson and Scottie Scheffler of Dallas 5 and 3 in fourballs.
"There are still a lot of points to play for tomorrow," European captain Stuart Wilson said. "My players will have no problem getting motivated for tomorrow."
Morning played was delayed 90 minutes because of frost.
