While the unbeaten US lead Group A with one preliminary game remaining against France on Sunday, they have been plagued by turnovers in their last two contests and been unable to showcase the dominance that has long been their trademark.
But despite some uneven play, there was no panic in the US camp as players treated the near upsets as learning experiences ahead of the knockout phase of the 12 team tournament.
