Records: United 3-9-3, 12 points; Sounders 4-8-4, 16 points.

Outlook: The secondary transfer window opens for MLS on Thursday, and there's a chance newcomers Pablo Hernandez and Branko Boskovic could take the field for United if they receive their international transfer certificates. . . . United defender Juan Manuel Peña might miss Thursday's match, and Sunday's match against Los Angeles, with a quadriceps strain. . . . After limping to a 1-8 start to the MLS season, United has registered a point in five of its past six league matches (2-1-3), including a 3-2 win at Seattle on June 10. . . . Seattle has lost five of its past seven MLS games.
