The MLS Cup was perched prettily on the sideline, with both clubs looking to win its first.
League MVP David Ferreira got the ball rolling by ghosting between the centerbacks and finishing off a whipped-in Marvin Chavez cross.
Other than that goal, Drew Moor kept Atiba Harris and the rest of FCD's attack quiet.
Pablo Mastroeni and the Rapids midfield started imposing themselves on the injured Daniel Hernandez and his cohorts.
Conor Casey bundled in the scrappiest of goals in the second half to level the score.
In extra time, a fluky Mac Kandji toe-poke deflected off George John's thigh and in for the winner.
Ugly or not, that goal proved enough for Mastroeni to lift his and the club's first MLS Cup.
The finality of the loss begins to seep in for Ugo Ihemelu and Dax McCarty.
It wasn't champagne soccer, but Colorado busted out the bubbly in the locker room either way.
