Buis combined with Spaanstra, who was making her tournament debut, to win 3-6, 7-6, 7-6 in a thrilling pool phase contest that lasted nearly four hours.

Kamiji and Whiley, the defending champions, had made history this year by becoming the first non-Dutch pairing to win all four Grand Slam titles in a calendar year.

"We are so excited about this win," Buis told the International Tennis Federation.

"We went on court with a plan and stuck to that plan.

"Today was about playing smart.

"This is the first major tournament we've played as a couple.

"The start couldn't have been any better."
