After an unbeaten three-game start, Great Britain's inexperienced team at the World League finals tapered away to finish with two defeats.
Having missed out on the semi-finals following a 2-1 loss to India, GB - with Ulsterman Ian Sloan in their ranks - lost their next game 4-2 to Argentina.
They had no answer to the penalty corner prowess of Pedro Ibarro and Gonzalo Peillat, who both put away two set-pieces, with GB's goals coming from Simon Mantell and Phil Roper.
Many regulars had been rested and, after topping their pool, it looked good for the young team before the wheels finally came off.
Meanwhile, Ulster Elks' EY Irish Hockey League game with Greenfields, which was scheduled for Jordanstown this afternoon, has been postponed.
The Connacht side were advised not to travel due to the gale-force winds which battered Galway last night, leading to dangerous driving conditions.
South African international Erin Hunter was due to make her first-team debut in today's game but that will now take place when the Elks play league leaders Hermes next weekend.
