Seattle Sounders left it late to come back and secure a 3-2 win at the Portland Timbers.

Jeff Parke's own goal put them behind a minute after half-time, only for Freddy Montero to level after 57 minutes.

Jorge Perlaza regained Portland's lead with 21 minutes remaining but, after Montero scored again, Seattle won it from the spot, Osvaldo Alonso scoring with seven minutes left.

Portland's Eric Brunner was sent off for giving away the penalty, bringing down Lamar Neagle.
