The Union rebounded from the bad taste left by losing the U.S. Open Cup final with a creditable scoreless tie in Columbus on Saturday.
It could have been a win, though, had a first-half goal not been taken away by a controversial video review.
In the 36th minute, the Union (14-12-5, 47 points) appeared to score when Cory Burke won a duel with Lalas Abubakar and forced Jonathan Mensah to put the ball in his own net. But referee Drew Fischer overturned the goal after a lengthy review process (and after a lot of Crew players got in his face to complain), judging that Burke fouled Abubakar in the tussle.
