Sisters Morgane and Kim Metraux combined for a 7-under 137 on Wednesday to give Switzerland a one-stroke lead over South Korea in the Women's World Amateur Team Championships .
Morgane opened with a 68, and Kim shot 69 at Mayakoba El Camaleon. They are teammates at Florida State .
The 19-year-old Morgane played her final nine holes in 5-under 31, following two birdies with an eagle. She also closed with a birdie to help Switzerland top the team leaderboard .
"I actually had a bad nine to start with a double bogey, but I made a 90-foot putt for an eagle on the fifth hole, my 14th," Morgane said. "I just focused and the score just came. It is always better to just try to enjoy the day. I think I only missed one or two fairways, which is the key here."
She was tied with South Korea's Hyun Kyung Park atop the individual leaderboard .
The 21-year-old Kim had four birdies and a bogey.
"It's always good to see your country's name," Kim said. "It's always good at the top of the leaderboard."
Azelia Meichtry's 73 did not count in Switzerland's team total.
South Korea played on the Iberostar Playa Paraiso layout, counting a 68 from Hyun Kyung Park and a 70 from Hye Jin Choi.
"I didn't expect to be tied for the lead on the individual leaderboard, but I am very happy," the 16-year-old Park said. "I am really willing to make history and win the championship as Korea did in 2010 and 2012 because those players have had great success on the LPGA Tour and I want to follow in their footsteps so that other juniors can look up to me the same way I look up to them."
Japan was third at 142, also playing at Mayakoba El Camaleon. Nasa Hatoaka and Hina Arakaki each shot 71.
The United States was tied for seventh at 2 over. Katelyn Dambaugh had a 72, and Mariel Galdiano and Andrea Lee each shot 74 at Mayakoba El Camaleon.
