Caltex Socceroos fullback Brad Smith will be the first Australian to play for American soccer's biggest prize after booking a Major League Soccer Cup final ticket in a huge upset.
Smith's Seattle Sounders defeated dominant top seeds LAFC 3-1 in Los Angeles on Wednesday (AEDT) in the Western Conference final.
LAFC had broken records for points, goals and goal difference during a 2019 campaign many believe is the best in league history.
But the 26-year-old from Penrith - who is on-loan from Premier League club Bournemouth - helped shut down one of the most dangerous attacking teams ever to grace the MLS, and nullify the threat of former Arsenal forward and MVP favourite, Carlos Vela, to secure Seattle a Cup final berth.
It is Washington-based Seattle's third MLS Cup in four years.
Raul Ruidiaz's double and a strike from Nicolas Lodeiro saw Sounders storm home after Eduard Atuesta's 17th minute opener.
Smith has featured 28 times in the MLS this season, registering five assists.
Seattle will host either Toronto FC or defending champions Atlanta United.
