"We scored a lot of goals and we used our chances well," she said after Monday's opener in Shanghai. "But we made too many mistakes. To get into a real flow that match has to be more balanced."
The rout began in the 12th minute and ended at the final whistle in similar fashion. Argentina goalie Vanina Correa knocked the ball into her own goal.
In between, the beleaguered Correa gave up nine goals, including hat tricks by Prinz (goals in the 29th, 46th and 59th minutes) and Sandra Smisek (goals in the 57th, 70th and 79th minutes).
The score was 4-0 inside the first half hour. It was 8-0 within the hour, and 10-0 after Smisek's third goal in the 79th minute.
Prinz said her team wasn't trying to run up the score.
"We try to play the best football can," she insisted.
