After splitting two very close sets against two-time Grand Slam champions Ekaterina Makarova and Elena Vesnina, Hingis and Mirza - who were playing just their second Grand Slam together - saw their hopes of a first major fading away as they fell behind 5-2 in the third set, a game away from going out.
But a fierce rally saw them draw level at 5-all, and after a roughly half hour break for the Centre Court roof to be closed due to fading light, the No.1-seeded Swiss-Indian duo came out stronger, breaking the No.2-seeded Russians one last time then serving it out for a gritty 5-7, 7-6(4), 7-5 victory.
"I had a great partner to pull me through. It takes guts and courage being down 5-2 in the third set and coming back to win. Couldn't have asked for more drama how to win it," Hingis said after the match.
"When we came back out at 5-all, we had goosebumps. The energy on the court, we were getting a standing ovation, it was just unbelievable. We both knew this is what we play for, work for - this energy.
"I think I'm speaking for both of us when I say we feel privileged to be here."
"It's definitely the crowd who made us win this match in the end," Hingis commented.
"The energy was unbelievable," Mirza added.
"You started hitting your forehand even bigger," Hingis said.
It was a milestone for both of them - Hingis won her 10th Grand Slam doubles title, and first since the 2002 Australian Open with Anna Kournikova, and Mirza won her very first Grand Slam doubles title.
Mirza is now the first Indian ever to win a Grand Slam women's doubles title.
Hingis and Mirza, the No.1-ranked team in the world, will return to No.1 on the Road To Singapore doubles leaderboard, the journey to the BNP Paribas WTA Finals Singapore presented by SC Global.
