DALLAS - The Portland Timbers will have to wait until at least July for their first road victory.
The Timbers suffered their worst defeat of the season on Saturday night, falling 4-0 at FC Dallas.
Dallas scored in the 34th, 39th, 58th and 87th minutes, and Portland got only of its seven shots on goal as it slipped to 0-5-2 away from Jeld-Wen Field.
"We were very poor," Timbers coach John Spencer said. "From the first moment to the last, we never matched them at all, never got close to them, never tackled them, never ran with them."
The Timbers are 5-7-3 overall (18 points), and sit seventh in the nine-team MLS Western Conference.
Dallas improved to 9-4-4 (31 points) and is second, four points behind Los Angeles and having played two fewer games than the Galaxy.
The Timbers won't get another chance on the road until July 16, but that game will be against 2-4-10 Chicago.
Portland's next two matches are at home, against 4-6-5 Sporting Kansas City (8 p.m. Saturday) and 7-4-7 Seattle (2 p.m., Sunday, July 10).
Kickoff temperature Saturday in Dallas was 93 degrees, and the home team took command with two goals off corner kicks in the first half. Midfielder Daniel Hernandez's kicks led to scoring headers by defenders Zach Loyd and George John.
Portland hasn't scored first in any of its seven road games.
In the second half, Dallas midfielder Brek Shea scored off a rebound, and forward Ruben Luna knocked in a long shot tipped by Timbers goalkeeper Troy Perkins.
Perkins finished with six saves, and Dallas totaled 21 shots.
Dallas keeper Kevin Hartman posted his league-leading eighth shutout.
"Excellent performance tonight by FC Dallas against a very good team that has two good strikes and a team that plays a lot off free kicks and corner kicks," winning coach Schellas Hyndman said. "They had scored 18 goals on restarts, so it was something we were careful with. Our players all stepped up tonight. You can't put a finger on any one (player) who was exceptional. They all had a good game."
The outcome avenged Dallas' 3-2 loss at Portland on April 17 - and Dallas felt better than it had after a 4-1 home loss to Sporting Kansas City on June 12.
"The last game (at home) we got smoked," John said, "so we wanted to make a point today and treat our fans to a win. We wanted to prove that this is our home field and it's tough to beat us out here."
Added Hernandez: "We kept putting pressure on Portland. It's a tough place to play with the heat, and I thought everyone who participated tonight did a great job."
