The Spaniard went on to achieve the No. 1 ranking in September after the US Open, finishing the year at No. 2.
She also won the title at the Western & Southern Open in Cincinnati, reached the semifinals or better at Brisbane, Rome, Birmingham, Stanford, and Tokyo PPO, and was the first to qualify for the 2017 BNP Paribas WTA Finals Singapore presented by SC Global – her third appearance at the event.
Muguruza and Rafael Nadal, the ITF men’s world champion, both represent Spain – marking the first time since Americans Pete Sampras and Lindsay Davenport in 1998 that the men’s and women’s ITF World Champions are from the same country.
Muguruza said: “Becoming ITF World Champion in such a competitive year is amazing for me and is even more special because Rafa [Nadal] has also been awarded on the men’s side. He is a great role model for all of us, so it is a great moment for tennis in Spain.”
After pairing up in the spring, Chan and Hingis also enjoyed an outstanding first season together to end 2017 as the No. 1-ranked team.
