Republic Of Ireland ace Sinead Farrelly is an NWSL champion after her Gotham FC side beat OL Reign 2-1 in Saturday night's decider.
Farrelly was a second-half substitute in a game which saw Spanish striker Esther Gonzalez head the winner to secure Gotham's first Championship title as American veteran Megan Rapinoe's final career match came to an early and bitter end.
Forward Lynn Williams got the scoring started for the New Jersey/New York club, as Gotham capped a Cinderella run through the postseason only a year after they finished at the bottom of the table for the top-flight American league.
The showdown between Gotham and Reign marked the highly anticipated final match of twice World Cup winner Rapinoe's career but the retirement party came to an abrupt end as the Seattle forward exited minutes into the affair with an injury.
A superb solo effort from Rapinoe's World Cup team mate Rose Lavelle got Reign on the board in the 29th minute but Seattle were unable to convert on a series of second-half efforts in their third appearance in the NWSL title match.
"We stuck to our plan, we committed to each other... and we know how good we can be," said Gotham defender Ali Krieger, a beloved fan favourite who will also hang up her boots for the last time after Saturday.
The raucous affair at San Diego's Snapdragon Stadium got off to a grim start as Rapinoe went down in the third minute and Krieger ran to embrace her former US national team mate before she could exit the pitch.
Gotham forward Midge Purce beat three Seattle defenders down the right side before sending a perfect cross to Williams, who slipped the opening goal past Reign keeper Claudia Dickey from the center of the box in the 24th minute.
Midfielder Lavelle answered five minutes later, charging at the Gotham keeper Mandy Haught and sending one into the back of the net with a superb left-footed strike.
Gotham were denied twice in the 38th minute as Purce hit the left post and midfielder Delanie Sheehan hit the crossbar in rapid succession.
Reign had the chance to take the lead as Lavelle tried a through ball but striker Jordyn Huitema was caught offside five minutes later.
Months after she hoisted the World Cup trophy with Spain, Gonzalez powered a sublime header past the Reign keeper off a corner from Purce in first-half stoppage time and pumped her fist in celebration.
The final moments of the match were drenched in drama when Haught was shown a red card for putting her hands on the ball outside the box and Gotham midfielder Nealy Martin put on the goalkeeper's jersey as her team were out of substitutions.
Martin's team mates blocked a free kick by Lavelle and Gotham erupted in celebration as Reign's frantic final efforts went unrewarded. Purce took MVP honours for the match for her two assists.
"We had so much experience to the very last game and we were so, so excited to just come out here and enjoy the atmosphere... and enjoy each other one last time," said Krieger afterwards. "I'm so happy we can go home with this trophy."
