The Rapids controlled the run of play through the first half and pushed the Union defense more than once. The best chance of the first 45 came just past the half-hour mark, as Luis Solignac received a throughball in the box from Dillon Serna, and appeared to have the space to send a quick shot on goal. But the Argentine instead opted to take a couple of touches, allowing a Union defender to get in position, by which time Solignac's shot went over the goal.
A few minutes later, Tranquillo Barnetta took an unorthodox free kick on the other end, trying to play pinball off the various players in the box, but the Rapids were able to block his chance and regain control of the ball.
The teams picked up the tempo in the second half and the visitors, on their second game of the week, got more into the action in the second 45.
Two Rapids players hit the crossbar in the second half, Dillon Powers in the 70th minute and Solignac 10 minutes later. And then the controversial call of the night came right after Solignac's shot clanged off the bar, as the ball recirculated and Powers' cross was finished by Solignac. But the tally was chalked off by the AR for an apparent offside, even though initial replays made that call look incorrect.
The game broke open in the final minutes, however. First, it looked like Sam Cronin won the game for Colorado in the 87th minute, as his header off Marlon Hairston's cross put the hosts ahead 1-0.
But just as it appeared the win was wrapped up, Brian Carroll, of all people, made a run into the box, took down a pass and finished well in the 92nd minute to tie up the game.
So the perfect record at home is dashed for the Rapids. Still, losing just two points in seven games ain't all that bad.
The Rapids now have a little over two weeks off from game action, as they won't be back in action until the U.S. Open Cup on June 15.
