Robbert Kemperman scored in the dying minutes on Tuesday as the Netherlands struggled to a hard-fought 2-1 victory over South Korea at the Hockey World Cup.
The Koreans scored early through a Nam Hyun-woo penalty corner and then defended stubbornly for the rest of the match. Jeroen Hertzberger brought the scores level in the 21st minute, also from a penalty corner, before Sander de Wijn dribbled to the line and pulled the ball back for Kemperman to fire home his last-gasp winner.
