Six of seven champagne bottles cooling in a locker room metal tub went unopened after Minnesota United clinched a playoff spot on Sunday's MLS Decision Day.
The Loons' 2-0 victory over Western Conference rival Vancouver came before a record Allianz Field crowd and brought relief as much as it did exuberance for a team that ended a six-game winless streak when it mattered the most.
"I popped one," Loons veteran midfielder and captain Wil Trapp said. "I'm not sure all the guys understand the tradition."
The Loons advance to the postseason for a fourth consecutive year, doing so on the regular season's final day just as they did in the final ticking moments at L.A. Galaxy last year.
Sixth place when Sunday afternoon's action around the league was all over, the Loons play at third-place Dallas at 8:30 p.m. next Monday.
"I'm just so pleased for the players," Loons coach Adrian Heath said. "I think sometimes people think people don't care and they do care and I thought they showed that today."
Loons left-side attacker Franco Fragapane scored the game's first goal in the 17th minute while newcomer and second-half sub Jonathan Gonzalez added a second with his first MLS goal in the 77th minute.
Loons goalkeeper Dayne St. Clair then delivered the team's first clean sheet since July 16 by making a stunning save late in the game.
