Erick Torres scored in the 79th minute to help Chivas USA tie Portland, 1-1, on Saturday night, leaving the Timbers winless at 0-2-4.
Torres scored off a cross from Leandro Barrera for his fifth goal of the season for Chivas USA (1-2-3).
Will Johnson opened the scoring for Portland in the seventh minute. He scored for the first time this year after finishing with nine goals last season.
Maximiliano Urruti forced a turnover and got the ball to Darlington Nagbe, who slid a pass between two defenders and into enough open space for Johnson to run into it and knock a right-footed shot past Dan Kennedy.
Portland had a late chance when Johnson had a free kick just outside the penalty area, but his shot hit the post.
