Chicago Fire beats Columbus Crew SC, Seattle Sounders top RSL on penalties

The Chicago Fire are headed to the U.S. Open Cup quarterfinals after holding on to beat Columbus Crew SC 2-1 at the Windy City's Toyota Park.

David Accam got the hosts off to the perfect start when he fired home from distance in the seventh minute following an assist from John Goossens to beat Columbus goalkeeper Brad Stuver.

And it would be Accam again in the 29th minute, when he connected with a Rodrigo Ramos cross in the center of the box and beat Stuver once again with another right-footed shot.

With the Crew chasing an improbable comeback, Ethan Finlay cut the deficit in half from the penalty spot after a handball in the penalty area by Chicago'sJohan Kappelhof.

The Fire were able to hold on for the win, despite being somewhat dominated statistically, and will host the winner of Wednesday's last-16 match between Orlando City SC and the Fort Lauderdale Strikers of the NASL.

The Sounders got the better of RSL from the spot, with Miller saving two penalties and Jordan Morris, Herculez Gomez, Zach Scott and Erik Friberg all converting to give Seattle the 4-1 win.
