Union (4-2-3-1) 

Blake 

Gaddis-Marquez-Elliott-Fabinho 

Bedoya-Medunjanin 

Epps-Ilsinho-Picault 

Sapong 

Bench: McCarthy, Onyewu, Wijnaldum, D.Jones, Simpson, Alberg

Sounders (4-2-3-1) 

Frei 

Leerdam-Marshall-Alfar-Nouhou 

Svensson-Delem 

Jones-Roldan-Lodeiro 

Bruin 

Bench: Miller, Fisher, Wingo, Shipp, Kovar, Neagle, Dempsey 

- UPDATE: Chris Pontius misses out with an abdominal injury after originally introduced in the starting lineup. Marcus Epps is in on the win. Union go with 17 in the lineup.

- Two changes for the Union enforced by injury. Out go Warren Creavalle and Keegan Rosenberry; in come Ray Gaddis and Ilsinho, the latter playing the 10. That makes it closer to the customary 4-2-3-1 formation that the Union so often favor.

- Derrick Jones is back on the bench. It’s just his second time in the 18 since July 6.

- No Clint Dempsey for the Sounders from the start today, which puts the more bruising Will Bruin up top to battle with the Union defense. Watch for the interchange between Nicholas Lodeiro and Cristian Roldan: Roldan nominally starts centrally, but he and Lodeiro should move positions plenty, making a lot of work for the backline and Haris Medunjanin to track.
