Paris - Leander Paes and Martina Hingis completed the mixed doubles Grand Slam on Friday with a 4-6, 6-4, 10-8 win over Sania Mirza and Ivan Dodig in the French Open final.
Paes, 42, and 35-year-old Hingis had already won the Australian Open, Wimbledon and US Open in 2015.
It was Paes's eighth mixed doubles title in all at the Slams to add to his 10 men's doubles wins in a run stretching back to 1999.
He had already completed the men's doubles Grand Slam.
"I won my first Slam here in 1999 on this court," Paes told a shivering handful of hardy fans inside Philippe Chatrier Court.
"Today we have completed a team Slam. Martina, you are a fantastic partner, I love you like crazy.
"You cover most of the court. You are a real champion."
Hingis, a five-time singles champion at the majors in her prime, now has five mixed and 12 women's doubles titles.
She won a first mixed title with Mahesh Bhupathi at the 2006 Australian Open.
Hingis and Mirza had also won the last three women's doubles at the Grand Slams but were knocked out in the third round at the French Open.
They slumped to a shock 6-3, 6-2 loss to Czech pair Barbora Krejcikova and Katerina Siniakova.
