Garbiñe Muguruza Blanco (Spanish pronunciation: [ɡaɾˈβiɲe muɣuˈɾuθa ˈβlaŋko]; born 8 October 1993) is a Spanish-Venezuelan professional tennis player and former world No. 1, currently ranked No. 15 in singles by the Women's Tennis Association (WTA). Since turning professional in 2012, she has won six singles titles, including two majors, the 2016 French Open and the 2017 Wimbledon Championships.
With powerful groundstrokes and an aggressive style, Muguruza came to prominence in 2014 on reaching the last 16 at the Australian Open, besting former world No. 1 Caroline Wozniacki en route. She then defeated then world No. 1 Serena Williams in the second round of the French Open, beating her in straight sets in Williams’ most lopsided loss at a Grand Slam ever, and reaching 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.
