If the Sounders beat Kansas City in the U.S. Open Cup match Tuesday at Starfire, they will host the semifinal round match against either the Houston Dynamo of MLS or the Charleston Battery of USL-1.
That game also would be played at Starfire.
Grandstand seating is gone for the Tuesday quarterfinal, but some $10 general admission tickets remain. Details at the Sounders site.
There won't be any radio or TV, however there will be a live audiocast on SoundersFC.com, with Thom Beuning and Peter Fewing doing the honors.
