SANTA CLARA -- Call it the Nightmare at Buck Shaw Stadium for the Earthquakes.
Torched all night by speedy Fabian Castillo, who had two goals and an assist, the Quakes suffered a humiliating 5-0 defeat to FC Dallas on Saturday night.
Tesho Akindele had a hat trick for FC Dallas (11-7-6) in front of a stunned crowd of 10,525, which witnessed the worst loss in Quakes history in terms of goal differential.
"They kicked our (butt) from minute one to minute 90," Quakes goalkeeper Jon Busch said. "Very disappointing. We're at home. It's embarrassing."
Every time Castillo found a seam, it was big trouble for San Jose, which saw its four-game unbeaten streak snapped in a big way.
"You can't defend like that at this level and expect to have any chance to get a result," coach Mark Watson said. "Credit to their players. Fabian Castillo had a great night. We couldn't handle him."
Argentine Matias Perez Garcia, in his much-anticipated home debut, displayed his many skills in the middle but left the field frustrated.
FC Dallas extended its unbeaten run to nine, but no one could have expected this effort from the Quakes (6-9-6). They needed a win at home with nine of their final 13 games away, including at second-place Seattle on Wednesday and at Philadelphia on Sunday.
San Jose also fell into a tie for last place in the Western Conference, courtesy of Chivas USA's 0-0 draw against Vancouver.
After right back Shaun Francis left with a left leg injury early in the game, Brandon Barklage replaced him, and things continued to spiral downward for the normally solid Quakes back line.
How bad was it on defense?
Akindele made it 2-0 in the 43rd minute by rolling a slow shot off the post, the ball first going in between Jason Hernandez's legs.
Trailing 2-0 in first-half stoppage time after a terrible start, the Quakes wasted a chance to shift the momentum. Perez Garcia drew a foul in the penalty area, but Chris Wondolowski missed the free kick from the spot, sailing the ball over the cross bar.
"We have to throw this one away," Busch said.
In a bright spot, rookie Tommy Thompson, the Quakes' first homegrown player, made his second appearance in the 72nd minute and sparked the offense.
In the 16th minute, San Jose, which struggled to get out of its own end in the first 15 minutes, woke up. Perez Garcia juked through traffic on the right and fed Wondolowski, who dished to Sam Cronin in the seam. His blast toward the near post was knocked wide by goalkeeper Raul Fernandez.
Watson said the team prepared for Castillo, who has eight goals, by trying to come up with ways to keep him from turning and running at them.
"We couldn't handle them in any phase of the game," Watson said.
