Garbine Muguruza of Spain has been installed as the new world No. 1 in the latest WTA rankings. The 23-year-old Muguruza became the second player from Spain to take the No. 1 spot since the computer rankings began in 1975. For 12 weeks, Arantxa Sanchez-Vicario held the top spot for 12 non-consecutive weeks in 1995. Muguruza snatched the No. 1 spot from Czech Republic's Karolina Pliskova after she reached the round of 16 at the US Open.

Muguruza said becoming No. 1 is a dream come true, saying it was the only thing she wished for every birthday. “There is a lot of work behind this achievement and a lot of love and passion for this sport,” said Muguruza, who ended the eight-week reign of Pliskova.

This year, Muguruza captured her second Grand Slam title at Wimbledon and won her fifth career singles title at the Western & Southern Open in Cincinnati last month.
