Rowe, who came on in the 64th minute, gave the Revolution the advantage while Benny Feilhaber added another in the 73rd minute. Revolution goalkeeper Matt Reis made three saves to preserve the shutout, his second of the season.
The win snapped the Revolution’s two-game winless streak and upped their record to 5-7-1 (16 points). Meanwhile, the Fire dropped their second straight and fell to 5-5-3 (21 points).
The Revs and Fire struggled to find scoring chances in the first half, as Reis and Fire goalkeeper Sean Johnson were rarely tested.
Chicago nearly got on the board in the 48th minute when Orr Borouch sent it to Dominic Oduro, who’s header ricocheted off the post.
But the Revolution attack came to life in the second half. Six minutes after he entered the match, Rowe took a hold of pass from Feilhaber and flicked it through to put the Revolution on top.
Rowe returned the favor in the 73rd minute when he played a diagonal ball to Feilhaber, who redirected it past Johnson to cap the scoring.
