Great Britain's women continued their preparation for this month's Champions Trophy with a superb victory over world champions Argentina in Cordoba.
After opening the Four Nations with a 3-1 win over South Korea, goals from Kerry Williams and Crista Cullen saw GB beat hosts Argentina on Thursday.
The win means GB have already qualified for Sunday's final ahead of Saturday's last group game against New Zealand.
The Champions Trophy will begin in Rosario, Argentina, on 28 January.
GB coach Danny Kerry said: "It was a thoroughly professional and disciplined performance against a full-strength Argentina side. We showed excellent concentration, which allowed them very few opportunities while we created good chances of our own."
The Champions Trophy is the last ranking event before the Olympics and therefore significant for several of the eight nations involved.
Great Britain, who qualify automatically for the Games as hosts, have taken a squad of 22 players to Argentina.
