After an interchange between Nicolas Lodeiro and Tyrone Mears the right back drove in at a dangerous angle. Carlos Gruezo earned a yellow taking Mears down. That set-up Lodeiro to do what Lodeiro do, and he did it so well.
With the goal Seattle put themselves in control of their playoff destiny.
It also comes as Sounders FC look the stronger side on set-pieces of any variety. With the FC Dallas strategy of fouling Lodeiro likely to earn them another yellow card and plenty of more free kicks the Sounders can take charge in the second half.
