Seattle came into the match in scorching-hot form having won seven of their last eight league matches and started Friday's contest just as hot as the hosts took the lead just three minutes into the game.
Defender Andy Rose made the scoring play happen with excellent hustle to track down a ball along the end line. He whipped a low cross into the box for a completely unmarked Martins to smash home on the volley, sending the 55,107 fans into euphoria.
Real Salt Lake's best chance of the opening half came in the 31st minute when Joao Plata ran at the Seattle backline and ripped a right-footed strike from just outside the area, but it skidded wide of the left post.
The Sounders doubled their lead in the 38th minute when defender DeAndre Yedlin came charging down the right flank and sent a low cross into the area. Neagle was there to rip it home for his third goal in as many games.
RSL continued to look for ways to break down the Sounders back four, but the final ball was lacking all night as the Sounders claimed their sixth consecutive home win.
The result lifts Seattle to 49 points, one ahead of RSL atop the Western Conference. The Sounders also extended an incredible 46-match unbeaten streak when they score first.
