Maximiliano Urruti made a nice play to settle a bouncing ball and found Fernandez cutting in the right side of the box. Fernandez then muscled off a defender and finished the great feed past keeper John Berner.
Portland (8-8-12) scored first in the 43rd minute, as Diego Valeri's half-volley cleared Berner for his eighth goal of the season.
The Rapids (8-13-7) tied it at the 48-minute mark. Colorado was awarded a penalty kick on a disputed hand-ball call, and Dillon Powers converted the PK for his sixth goal.
