AP The fourth time was a charm for Seattle, who saw Honduran international Mario MartÃnez â making his first Major League Soccer start â blast the Sounders into the Western Conference final. His left-footed, 15-yard half-volley in the 81st minute beat Real Salt Lake goalkeeper Nick Rimando far post for the seriesâ only goal, the Sounders winning their first playoff series in franchise history. After dominating Fridayâs first leg, Seattle met an energetic RSL to start Thursdayâs match at Rio Tinto Stadium. After setting into the game mid-way through the first, the Sounders saw Real ascend through the second half, slowly gaining control of the match. Â The home sideâs climbÂ haltedÂ when MartÃnez, in the starting lineup for the injured Mauro Rosales, ended their season. With the win, Seattle moves on to their first Western Conference final, a two-legged series starting Sunday in Los Angeles against the defending champion LA Galaxy.
