In a World Cup group stage, goal differential is the first tiebreaker, meaning the USA had every right to continue scoring, a fact their players were quick to highlight after the game.
Samantha Mewis opened the floodgates five minutes after the break as the USA made life miserable for the Thais by regularly finding the back of the net. "We've got two more games to play and we need to bounce back".
"When you get a deluge of goals like that, it's a good feeling", Ellis said.
"When you're playing in a World Cup, every single goal may count at the end of the day", Morgan said. The match was over after just 12 minutes in thanks to the onslaught of goals, as Jill Ellis' team sent the rest of the world a message in their opening match of the group stage.
"I think they could have won with humility and grace but they couldn't manage to do that". Morgan put her arm around Thailand's Miranda Nild, who was wiping away tears on the field.
Asked repeatedly about the lopsided score, US coach Jill Ellis wondered if a 10-0 victory in a men's World Cup would elicit the same questions.
"They were disappointed of course, they meant to make an impression in this first match and they were disappointed", coach Nuengruethai Srathongvian said through a translator.
Morgan, who was seen consoling Nild after the game, was asked what she said to her fellow Golden Bear. "Yes, they are all athletes and they will be resilient".
Morgan opened the goal spree for the title favorites, who are in pursuit of a fourth world crown, with a header in the 12th minute and from then on there was no stopping the champions. And I think that to be respectful to opponents is to play hard against opponents.
It came close to the team's biggest rout ever.
After netting four times in six minutes shortly after the restart, they then added six more goals in the last 16 minutes.
Sweden, who defeated Chile 2-0 earlier on Tuesday in Rennes, ousted the U.S.in the teams last meeting in the quarterfinals of the 2016 Olympics in Brazil. The match was essentially over just 54 minutes in when the Americans went up 6-0, though it could be argued it was over long before that. For comparison, the US had 39 attempts.
