Amsterdam: Netherlands defeated South Korea 2-0 in the semi-final pool at the women's Champions Trophy field hockey here on Saturday, denying Argentina, world champions and defending titleholders, a place in Sunday's final.

Argentina finished the semi-final pool level on four points with South Korea but miss out as the Koreans scored more goals and had a better goal difference.

Kim Lammers scored in the first seconds of play, taking a long pass from the backfield and carrying possession unchallenged into the circle to shoot past Korean goalkeeper Moon Young-hui.

South Korea defeated both penalty corners from the Netherlands by running down the powerful flick of Maartje Paumen.

Lidewij Welten scored Holland's second field goal late in the first half, making the rebound off Moon's pads from Marilyn Agliotti's hard work to carry possession out of the backfield and shoot from the right.

Korea earned three penalty corners for one clean shot on goal, saved by Joyce Sombroek, Netherlands goalkeeper.

Max Caldas, Netherlands coach, was delighted with his team's quick start.

"We had a great flying start with a goal in the first seconds and I am happy with the good win," Caldas said.

"Korea got the upper hand late in the first half and we lost a lot of one-one-one duels," Caldas said.

"Game against Korea will be different because we are playing the first prize so it will be a different style of game," Caldas added.

Lim Jung-woo, Korea coach agreed with Caldas' assessment.

"Today we were making sure we played in the final but the game on Sunday will be a different game as it is a final and we want to win," Lim said.

Earlier Argentina defeated New Zealand 3-2.

Argentina dominated the first half with three goals into New Zealand's open net by Soledad Garcia, Luciana Aymar and Moccia Sanchez in the first half.

New Zealand hit back when Clarissa Eshuis converted New Zealand's first penalty corner with a clean flick high into the net after the half time siren.

Charlotte Harrison scrambled the ball across the line off Eshuis' second penalty corner flick early in the second half.

Luciana Aymar attributed Argentina's attitude to its lack of power in the second.

"After New Zealand's second goal it was mentally hard for us to continue," Aymar said.

Hagar was pleased with New Zealand's performance.

"I am proud of the girls and we were unfortunate not to come away with a draw in the second half," Hagar said.

"We did better in the second half because we held possession longer and made more passes," Hagar said.

Sunday sees a repeat of all the matches from Friday and Saturday.

Germany play China for seventh place, England and Australia playoff for fifth position, Argentina and New Zealand play for bronze and Netherlands and South Korea play for the gold medal.
