Ferreira gave FC Dallas the lead in the ninth minute, though his goal had to be verified by VAR. Ferreira just stayed onside after corralling a pass from Michael Barrios, rushed into the box and beat Timbers defender Bill Tuiloma before unleashing a right-footed shot low and to the left of goalkeeper Jeff Attinella.
Portland got on the board in the 67th minute, as Sebastián Blanco found Cristhian Paredes at the far post on a cross, and Paredes' header beat Dallas goalie Jose Luis Gonzalez. Diego Chara also got an assist on the goal.
Gonzalez had five saves in the win, four of them in the second half, with the most dangerous a Portland scoring chance in the 55th minute.
The Timbers thought they had secured a penalty kick five minutes into second-half stoppage time when Larrys Mabiala's header appeared to glace off the left hand of Dallas defender Ryan Hollingshead while in the box. The play was ruled not to be a penalty after VAR review, and FC Dallas closed out the match.

FC Dallas return to the pitch on April 20 when they travel to Atlanta United FC. The Timbers remain on the road to play Columbus, also on April 20.
