USA team were doing quite good and they almost set up things to overtake Netherlands and dethrone from top spot, as they already done thier hard job by smashing thier tough opponent brutally while one more time to go in coming days, morever against Oman I do believe they will easily hit them hard. While compared to them Netherlands has same three matches left but they has to face Scotland in his last matches where things look like will be out of thier reach because we have seen in recent match how hardly they got punished by Scotland so let's see how both fight for top spot to dominate the tournament
If Scotland had not won their last match against the Netherlands, the scenario would have been different. In that case, the United States of America would have had to win every match to regain the number one spot.
However, in the current context, I would agree with you that the United States of America is playing well and as such, they have a high chance of winning as the upcoming matches are against Canada and Oman. Although there may be a competitive performance against Canada, it can be said that the United States of America will be able to win against Oman. Therefore, it can be said that the United States of America is going to achieve the number one rank again.
