Morgan's third goal was her best, and a product of escalatingly impressive moves.
It probably will be a long time before another team scores as many (or more) goals in a single match.
The USWNT will play their second group stage match against Chile on June 16.
The USWNT kicked off their first match of the 2019 Women's World Cup in Reims, France today with a big win against Thailand. She also questioned whether the men's national team would be under fire for a similar result.
It was something else, too, though.
"We knew that every goal could matter in this group stage game and when it comes to celebrations this was a really good team performance and I think it was important for us to celebrate together", Morgan said after the game. "There are kids watching this".
The US said they there was no malice in their victory. Greatness. The power of teamwork.
"For me, it is disrespectful", said former Canadian player Kaylyn Kyle.
"I'm happy just ignoring those comments", Morgan concluded.
"As a coach, I don't find it my job to harness my players and rein them in because this is what they've dreamed about", coach Jill Ellis told reporters after the game. It is not a sportsmanship argument. "They're the No. 1 team in the world".
The Americans charged through Canada four years ago to the final, beating Japan 5-2 to raise the trophy. Betsy Hassett (2009-12) played with Morgan for two of her seasons.
"For all that have issue with many goals: for some players this is [their] first World Cup goal, and they should be excited", Wambach tweeted. Playing hard for 90 minutes is in your athletic DNA.
Naturally, the players celebrated all 13 goals.
The criticism has had a sexist feel to it.
Morgan and Rapinoe are among the biggest stars in a squad who have made waves with their much-publicised fight for pay equality that saw them file a lawsuit against the US Soccer Federation in March, accusing the organisation of gender discrimination. "Celebrate. Would you tell a men's team to not score or celebrate?"
"You want the players to leave with a good feeling". I don't think so. "Just mandate it - they mandate all kinds of things". "We don't have any excuse, except they are better". It's sort of like the NCAA men's basketball tournament letting in small-conference winners not almost as good as SEC or ACC teams that didn't get in. The team's seven different scorers also set a tournament record. It just might not do any good against the US national team.
The United States figures to again win comfortably in its next match Sunday, vs a Chilean team ranked 39th in the world.
Games against top opponents give Thailand an opportunity to see how the team is progressing, with a goal of growing the game back home.
"I also love the United States of America". Their unity. Their muscle and joy.
"I would have hoped they could have won with humility and grace, but celebrating goals eight, nine, 10 the way they were doing was really unnecessary", Rustad said.
