Seattle Sounders scored four goals for the second time in a week as they overcame a FC Dallas fightback to earn a 4-2 win in their MLS clash.

The home side took the lead in the 16th minute when Eddie Johnson raced onto Osvaldo Alonso's headed ball and fired a volley into the bottom corner past Raul Fernandez.

Seattle doubled their advantage when Brad Evans played a through-ball for Lamar Neagle, who raced beyond the Dallas defence and rounded Fernandez before placing the ball into the net.

After the break, Dallas hit straight back as Kenny Cooper headed home Michel's dangerous free kick into the bottom corner to the net.

The visitors were level minutes later when Michel curled the ball straight into the net from a corner from the right-hand side with spectacular left-footed effort.

However, this parity lasted just minutes as Johnson fired Seattle back into the lead as he collected Neagle's through-ball and rounded Fernandez and smashed his effort home.

Dallas's task was made harder when they were reduced to 10 men when Blas Perez was sent off for an elbow on Leonardo Gonzalez.

Seattle ensured the points when Neagle lifted a cross into the area for Johnson, whose header was saved by Fernandez, but from the rebound Evans found Obafemi Martins, who made no mistake in slotting the ball into the goal.
