Bradley Wright-Phillips set up Grella's goal by blocking the ball into an open space just outside the 18-yard box. It was Grella's first touch after entering the game as a substitute and the 1,000th MLS goal for the Red Bulls (2-0-1) franchise.
Tony Tchani evened the score for the Crew (1-2-0) with a run to the far post and open-net finish after the deflection of Federico Higuain's corner kick.
Higuain received a second yellow card for a show of frustration in the 83rd minute and the Crew finished with 10 men.
