Argentina defeated South Korea 4-2 to reach 10 points in the men's field hockey Champions Trophy here Friday to give themselves a chance of a finals berth on Sunday. Argentina's best result in their three previous Champions Trophy appearances was fifth place in 1987 and 2003 but they must wait until the last two round robin matches to see if they will play in the final. If Spain beat Germany and Australia beat Netherlands, Argentina will be out of the final on goal difference.
