Garbiñe Muguruza Blanco (Spanish pronunciation: ; born 8 October 1993) is a Spanish-Venezuelan professional tennis player and former world No. 1 who is currently ranked No. 2 in singles by the Women's Tennis Association (WTA). Since turning professional in 2012, she has won five singles titles, including two majors at the 2016 French Open and the 2017 Wimbledon Championships.
Equipped with powerful groundstrokes and an aggressive game style, Muguruza first came into prominence by reaching the last 16 of the 2014 Australian Open, where she scored an upset over former world No. 1, Caroline Wozniacki, en route. She then defeated Serena Williams in the second round of the French Open that same year, beating the then-world No. 1 in straight sets en route to the quarterfinals.
In 2015, at the Wimbledon Championships, she sailed to her first ever Grand Slam final where she lost to Serena Williams, and then went on to win her maiden Premier-level crown by capturing the China Open title. That same year, she also qualified for her first WTA Finals in singles scoring a perfect winning record in the round-robin stage before falling out in the semifinals to eventual champion Agnieszka Radwańska.
Muguruza has been successful in doubles, winning five titles, finishing runner-up at the 2015 WTA Finals and reaching the 2014 French Open semifinals. She achieved those results with her compatriot, Carla Suárez Navarro.
