FOXBORO - Midfielder Steve Ralston’s timely return to the lineup certainly rejuvenated the Revolution’s stagnant offense.

After sitting out four games with back spasms, Ralston recorded a goal and two assists in the second half to lift the Revs to a 4-0 victory over Chivas USA in a match before 7,606 last night at Gillette Stadium. Ralston extended his MLS career assist record to 128 while scoring his team-best seventh goal of the season.
