The 2014 Lamar Hunt U.S. Open Cup Final was a soccer match played on September 16, 2014, at PPL Park in Chester, Pennsylvania.

The Sounders were in the midst of a Supporters' Shield-winning regular season, while the Union's start was so poor that their coach was replaced a week prior to their first game in the competition.

Philadelphia secured its berth in the final by defeating the Harrisburg City Islanders, the New York Cosmos, the New England Revolution, and FC Dallas.

Seattle's road to the final included victories over PSA Elite, the San Jose Earthquakes, the Portland Timbers, and the Chicago Fire.

The coaches both chose strong squads in their attempts to win the trophy, though Sounders forward Kenny Cooper, later selected as Player of the Tournament, did not appear in the final.

The Union's alternative jersey, worn throughout the competition, featured a large letter "B" in the lower left corner to honor Bethlehem.

Their head coach John Hackworth was fired, and Jim Curtin was named as his interim replacement, a week before the first Open Cup match against their lower-league affiliate Harrisburg City Islanders on June 17.

A successful run in the Open Cup had the potential to salvage the season, and Curtin said that the team was taking the home game "very seriously".

[6] On June 24, Philadelphia played at home versus the New York Cosmos of the second-tier North American Soccer League in what was only Curtin's second game as head coach.

Overtime was again needed as the teams ended regulation tied at one apiece before Sébastien Le Toux scored the game-winner in the 115th minute.

Le Toux had a strong history with Seattle and the tournament before moving to the Union in 2009; he previously played for the second-division incarnation of the Sounders and won the 2009 Open Cup with the MLS side.

A dust storm accompanied by thunder and lightning halted the game for an hour after the 61st minute, but the Revolution could not recover from the two-goal deficit.

Goalkeeper Zac MacMath made diving saves of two Dallas attempts in the shoot-out to clinch the Union's place in the final—the closest the team had been to winning a trophy in its five-year history.

The Earthquakes second-string goalie, David Bingham, kept his team in the match by stopping three shots from Chad Barrett late in the second half.

Extra time saw the ejection of Portland's Diego Chara while Cooper and Marco Pappa both found the back of the net to give the home team a 3–1 victory.

The winner of the toss was whoever was victorious in the FC Dallas/Philadelphia Union semifinal, meaning that the game would take place at PPL Park in Chester, Pennsylvania.

[3] Philadelphia's Casey, Le Toux, and Cristian Maidana were significant attacking threats, while Seattle had the striking pair of Martins and Clint Dempsey.

Seattle also had a strong defense with young national team prospect DeAndre Yedlin, and eventual MLS Defender of the Year Chad Marshall.

[28] Although he won the Golden Boot for most goals scored, Cooper was primarily a bench player throughout the year and did not start the match.

[27] Although lacking those playmakers, the Sounders came out attacking, and their first big chance came in the 10th minute when Rose slung a low cross near the face of the goal to Dempsey, whose resulting shot was off-frame.

[29] The Union increased its pace with Andrew Wenger playing wide on the left where he repeatedly got past Yedlin to get to the byline or cut back to shoot.

Maidana and Le Toux strengthened Philadelphia's position by combining on the other side of the field to penetrate Seattle's defense.

[30] Wenger connected with Le Toux who took a shot, but Seattle goalkeeper Stefan Frei was quick enough to make the stop.

[28] Valdes had an excellent opportunity to tie the match in the 111th minute when he made a header towards the Sounders goal, but the shot was weak and easily saved.

"[35] A writer for Sports Illustrated quipped that "Schmid's decision not to start Obafemi Martins and Pappa was confusing — and then looked like a stroke of genius", as both were integral to the Sounders offense in the later stages of the game.

"[32] Curtin's leadership on the road to the final helped convince the players, fans, media, and front office of his ability to manage the club.

[34] After the game, a writer for The Seattle Times panned the broadcast arrangements and low attendance at PPL Park, saying, "It's a shame so few were able to see it.
