Clint Dempsey converted a penalty kick in the final seconds of stoppage time on Sunday night, lifting the Seattle Sounders to a 2-1 victory over Minnesota United.
A corner kick by Seattle's Joevin Jones floated into the penalty area, and Minnesota's Jermaine Taylor was called for a hand ball in a scrum of players battling for possession.
Dempsey stepped up soon after and drilled his kick to the right side past Loons goalkeeper Bobby Shuttleworth in the fourth minute of stoppage time for his 11th of the year.
Referee Ismail Elfath blew the final whistle as soon as Minnesota kicked off following Seattle taking the lead.
Chad Marshall also scored for the Sounders, who tied a club record by extending their unbeaten streak to nine games equalling an identical run of six wins and three draws from May 28-July 16, 2011.
Seattle was forced to rally after its club-record shutout streak ended at 421 minutes on a goal by Minnesota's Ethan Finlay in the 21st minute.
The Loons are still looking for their first road win of the season, having lost eight and drawn two away from Minneapolis.
