Great Britain's women won the Olympic test event after a bruising encounter with Argentina which did not come without cost.
Leicester defender Crista Cullen scored two second-half penalty corners but went off injured immediately after the second with an ankle problem.
Main striker Alex Danson later went off with a left shoulder injury and was taken straight to the dressing room for treatment.
Cullen did, however, attend the post-match trophy presentation albeit on crutches.
The only chance of the first half fell to Susie Gilbert but her sliding deflection was turned behind by goalkeeper Laura dell Colle.
Two minutes into the second half Cullen struck with a low flick and she added the second five minutes later, although got injured in the process.
Danson then left the field in tears after a collision with a defender.
Argentina rarely threatened and GB finished the competition without conceding a goal in all four games.
Great Britain coach Danny Kerry was unhappy that Argentina's approach to the game was not clamped down on by the umpires.
And he while he was reluctant to criticise, he felt the disparity between the professionalism put in by the world's top nations and the standard of officiating needed to be addressed.
"High-performance teams spend a lot of time looking at videos, having criteria by which we judge things, and I think officiating has to match that," he said.
"They (umpires) have to understand what is going on. That will only come with a performance environment around that.
"There was stuff going on out there today which I think, if you play, watch or coach hockey a lot, you would know exactly what was going on.
"I have probably already said too much but that is how I feel about the game today."
Kerry said he expected Cullen's sprained ankle to be "fine" but was unsure about Danson until a more detailed examination had been carried out, which is an obvious concern with the women's Olympic squad set to be named on May 18.
