Italian doubles specialists Sara Errani and Andrea Vavassori completed their "mission" by beating singles stars Iga Swiatek and Casper Ruud to win the controversially revamped US Open mixed event.
Errani and Vavassori, whose place in the new-look tournament was initially under threat, defended their crown with a thrilling 6-3 5-7 10-6 victory secured at almost midnight in New York.
The pair walked away with the increased prize pot of $1m (£740,000) designed to attract superstars like Swiatek, Carlos Alcaraz and Novak Djokovic - five times more than the $200,000 (£148,000) they won last year.
Enticing the singles players meant Errani and Vavassori were the only recognised doubles pairing in the 16-team draw.
