If you're involved in Sounder at Heart's third (fourth?) annual US Open Cup pickem, or if you're curious to know whether Seattle will have to fly to Tampa for their match, or if you want to know how the U23s are doing against USL Pro competition, this is the thread for it.
Broadcasts are sporadic. The U23s kicked off at 4 and there's no media for that game other than Twitter updates. The mega info dump on the games is available as always from TheCup.us.
Some of the matches are on http://www.uslnation.com/uslpro/ . . currently USASA's Icon FC against the Richmond Kickers and Dearborn versus the Dayton Dutch Lions. Later on the Timbers U23s will have a stream from Jeld-Wen.
