For only the second time this year, and MLS side has put five past another in league play with no goals in response.
New England accomplished the feat May 11 with a 5-0 win over Seattle, and while other teams have scored five, Dallas is just the second to do so without letting any in.
Tesho Akindele and Fabian Castillo stole the show, Akindele with a hat trick and Castillo with two goals and an assist. Castillo was especially active, recording eight shots (four on goal).
The goal glut also means that FCD now has the league's most potent offense, with 43 goals scored, and the third-in-the-West Hoops (11-7-6) open up a five-point gap over fourth-place LA following the Galaxy's heavy loss to Columbus (although LA has three games in hand).
Those on the losing side were left shellshocked by the result.
"It’s very poor and it’s very disappointing," said 'Quakes boss Mark Watson. "I thought this team was in a good moment. There was a good feeling about the team, and to have that kind of performance in what was a pretty important game is really deflating."
"They kicked our ass from minute one to minute 90," said veteran goalkeeper Jon Busch. "It’s embarrassing. I’m embarrassed. Every one of us should be embarrassed. If I was a fan, I would be pissed off with that performance from every single one of us tonight. We’ve been on a roll and that was a kick in the nuts.
"It can’t happen again. It’s embarrassing."
