After replacing Nate Jaqua in the 60th minute as the Sounders final substitute, Montero hit a shot from 40 meters that Metapan goalkeeper Misael Alfaro fumbled off the bounce and allowed to spin into the net.

Montero, who leads Seattle with six goals this season in Major League Soccer, sends the Sounders to Central America for the second leg at Estadio Jorge Calero Suarez on August 3. The winner advances to the Group Stage and be placed in Group C with Monterrey, Saprissa and either Tauro or Marathon.

Seattle has most of the possession throughout and Steve Zakuani had an open header from 10 meters in the 74th, but Alfaro made the save. Two minutes later, Taylor Graham's downward header off a corner sailed over the bar for Seattle, which qualified for the continental championship by winning the Lamar Hunt U.S. Open Cup in its inaugural season last summer.

Seattle's Sanna Nyassi nearly sealed the victory in the 81st minute, but his low, hard shot from the edge of the 18-yard box was directly at Alfaro. Nyassi found space again three minutes later, taking a touch into the box, but the Gambian missed the far post by the slimmest of margins after having beaten Alfaro.
In the 90th minute, Metapan had a chance to equalize, but Alfaro's free kick went off the Sounders wall.
Two minutes into stoppage time, Seattle nearly took a two-goal advantage into the second leg, but Zakuani's deflected header was saved nicely by Alfaro, who got a hand on the shot off the bounce on the turf before it tucked inside the far post.

A physical first half featured five yellow cards by Mexican referee Ricardo Arellano, but no goals. Seattle, though, had the better of possession and the scoring chances, but they rarely challenged Alfaro.

In the 21st minute, Sounders FC fullback James Riley burst down the right flank and played a perfect through ball to Nyassi, who connected with Miguel Montano at the far post, but the Colombian on loan from Quilmes bounced his header wide of the target.

Three minutes later, Osvaldo Alonso, who replaced an injured Peter Vagenas in the 14th minute, took a free kick from the edge of the 18-yard box following a dangerous kick by Metapan defender Erick Prado. But the Cuban's shot deflected wide of the net.

On a counter in the 28th minute, Roger Levesque had an open attempt from 16 meters, but his shot also deflected out for a corner kick.

In the 39th minute, Michael Seamon misses the target from 30 meter and, on another set piece two minutes from halftime, Alonso again drilled a shot into the Metapan wall.
