BBVA Compass Stadium - general and fans shot - Houston Dynamo

For the first time since 2013, the Houston Dynamo are one step away from MLS Cup, and their fans are eager to root them on.

The Dynamo announced on Friday that all reserved seats for the first leg of the Western Conference Championship vs. the Seattle Sounders, set for BBVA Compass Stadium on Tuesday, Nov. 21 (9:30 pm ET | FS1, FOX Deportes in US, TSN, TVAS in Canada) have sold out, leaving only a few standing-room only and secondary-market tickets available.

“This is an extremely exciting moment for our club, our fans and our city,” said Dynamo president Chris Canetti in a club release. “We want to deliver the biggest home field advantage possible for our team, and with more than 22,000 very vocal Dynamo fans singing and chanting together, we know that it will be.”

The Dynamo encourage fans still seeking reserved seating options to utilize the club’s only sanctioned resale platform. This will be the second all-time postseason meeting between Houston and Seattle; they also faced off in the 2009 Western Conference Semifinals, with the Dynamo advancing 1-0 on aggregate in the two-leg series thanks to a goal from Brian Ching in the 96th minute of the second leg.

The higher-seeded Sounders will host the second and decisive leg of the series on Thursday, Nov. 30 (10:30 pm ET | ESPN, ESPN Deportes in US, TSN, TVAS in Canada). Seattle lead the all-time series between the teams with a 6-4-6 record, but Houston are one of MLS’ best teams at home this year with a combined regular-season and playoff record of 13-1-4 at BBVA Compass Stadium.
