Hingis, 34, who has won 11 Grand Slam doubles titles, and three time mixed doubles Grand Slam winner, Mirza, were the top seeds in their first tournament together and lived up to expectations by winning the event and not losing a set all tournament.
After winning the first set 6-3 they fell behind 2-4 before winning four games in a row to rake the title in straight sets.
Hingis has won four doubles titles in the past year, two each with Sabine Lisicki and Flavia Pennetta.
In a chat with media after their win, Hingis praised her new partner Mirza saying she was delighted with their first tournament win together.
"This is something we were hoping for. She hits a big forehand, especially on the right side, and I can move and finish off the point. She prepares; I finish. That's pretty cool to me," Hingis said.
"I'm very happy we made this move. Obviously we had partners we played well with, like me last year with Flavia, and changing was a big move. I'm very happy it worked out, because you never know what to expect.
"Winning the tournament in our premiere, it's new energy, and hopefully we can keep it up," she added.
Mirza, 28, confirmed what Hingis said saying their playing styles made them gel on court.
"She's one of the best people who can complement the way I play," Mirza said.
"She's got probably some of the best hands in the world at the net. For me, I need that. I need someone who can finish the balls off where I set them up," she added.
