The Mexican earned his team a vital away win and continued his impressive run of form as San Jose lost its third straight 1-0 game.
Torres scored the game's only goal in the 53rd minute. Mauro Rosales' cross hit two defenders but fell to the criminally unmarked Torres, who brought the ball down and finished at Jon Busch's near post.
The goal ties Torres with Dom Dwyer in the MLS Golden Boot race. Leader Bradley Wright-Phillips has 12.
The win moves the Goats off the bottom of the West past the Quakes. Chivas, with two straight wins, is now 4-7-5 on the year. San Jose is 4-7-4, and hasn't scored since May 31. It has lost its last three games by 1-0 scorelines.
