Sky Blue FC have secured the inaugural Women's Professional Soccer league title by defeating premiers and favourites Los Angeles Sol in the final at the Home Depot Center in Carson.

The New Jersey-based side continued their improbable run to the title having scraped into the semi-finals with a win on the final day of the regular season.

A goal in the 16th-minute from USA midfielder Heather O'Reilly proved enough to separate the two sides despite the star quality of the home side which included Brazilian star Marta, Japan's Aya Miyama, China's Han Duan and experienced USA international Shannon Boxx.

The home side continued to press for an equaliser throughout despite playing much of the match with ten players after Allison Falk was dismissed for a foul on Natasha Kai mid-way through the first half.

It was a remarkable start to the coaching career of Sky Blue's player-coach Christie Rampone, who only took over as the team's third head coach of the season in July.
