Outlook: United F Dwayne De Rosario (hip flexor) and MF Nick DeLeon (ankle) will not play. United begins the second half of the MLS season with two western away matches in five days. After Wednesday’s match, the club will practice in Seattle for two days before traveling to Denver for Sunday’s game against the Colorado Rapids. On the road, United is 0-5-2 with 10 goals conceded and one scored — a set piece resulting in Dwayne De Rosario’s long-range strike at FC Dallas on May 11. United has scored three goals in each of the past two U.S. Open Cup matches but has not posted a regular season goal in the run of play since May 19. Since then, both league goals came on penalty kicks. With Bill Hamid on U.S. national team assignment at the CONCACAF Gold Cup for as long as four weeks, Joe Willis is Ben Olsen’s top-choice goalkeeper. Andrew Dykstra, who has been on loan with third-division Richmond almost all season, is the back-up. The Sounders have scored 11 goals in three consecutive home victories.
