4 and five-time Grand Slam winner Maria Sharapova en route to the quarterfinals in Wuhan, earning her a first ever year-end top 50 ranking.

Her breakthrough year in singles came in 2015, winning a career-best 15 consecutive matches spanning two titles, upsetting Madison Keys and Petra Kvitová en route to the semifinals of the French Open (the first time she advanced past the third round of a major), reaching her first Premier Mandatory final at the China Open, and becoming the first Swiss female tennis player to be ranked in the top 10 since Martina Hingis in 2007.

[2] She won the silver medal in women's doubles at the 2016 Summer Olympics in Rio de Janeiro, partnering Hingis.

[4] She has one brother, Daniel, a music teacher and member of The Evpatoria Report, and two sisters, Sophie (musician and student) and Melinda.

[4] Bacsinszky's early tennis highlights included reaching the semifinals of three junior Grand Slam tournaments in 2004–05.

Her breakthrough professional tournament was the 2006 Zurich Open, where she qualified then defeated Anastasia Myskina and Francesca Schiavone before losing to former No.

Most important was reaching the semifinals of the Diamond Games in February, winning three qualifying and several main draw matches before losing to world No.

With no practice and having to take time off work, she drove from Lausanne to Paris; she lost her first match but felt her passion for the game reignited.

Thus she hired Dimitri Zavialoff, former coach of compatriot Stan Wawrinka, and committed herself to reviving her tennis career.

She then reached the third round of the Australian Open followed by back-to-back titles in Mexico at Acapulco and Monterrey, beating Caroline Garcia in both finals.

Entering the China Open in poor form, Bacsinszky beat Italian Camila Giorgi, qualifier Mariana Duque-Marino, and three former top-10 players including Carla Suárez Navarro, Sara Errani and Ana Ivanovic to advance her first ever Premier-Mandatory final where she lost to Garbiñe Muguruza in straight sets.

She withdrew from the WTA Elite Trophy due to a left knee injury that had already forced her retirement in her first round match in Luxembourg.

At the Qatar Ladies Open, Bacsinszky defeated Bethanie Mattek-Sands and Yulia Putintseva before losing to eventual champion Carla Suárez Navarro.

In March, she reached the fourth round at Indian Wells beating Tsvetana Pironkova and Eugenie Bouchard respectively, but lost to Daria Kasatkina subsequently.

She then made a surprising semifinal run at Miami Open, beating Agnieszka Radwańska and Simona Halep, two top-5 players, back-to-back.

At the clay-court season, Bacsinszky won her fourth WTA title in Rabat, losing only one set in the tournament, and re-entered the top 10.

At the French Open, she beat Sílvia Soler Espinosa, Eugenie Bouchard, Pauline Parmentier and Venus Williams en route to her second straight quarterfinal, but lost to the unseeded Kiki Bertens.

[14] Coming to the grass-court season, Bacsinszky played Eastbourne but was defeated by the in-form Kristina Mladenovic in straight sets.

At the Summer Olympics, Bacsinszky suffered a first-round loss to China's Zhang Shuai; however, partnering with Martina Hingis for the first time in doubles, Bacsinszky earned her first Olympic medal, as they beat Daria Gavrilova/Samantha Stosur of Australia, Bethanie Mattek-Sands/CoCo Vandeweghe of the United States, Chan Hao-ching/Chan Yung-jan of Taipei and Andrea Hlaváčková/Lucie Hradecká of Czech Republic en route to the final, where the pair lost to Ekaterina Makarova/Elena Vesnina of Russia.

With injuries carried on from the Fed Cup, she had to retire in the first round of Doha and eventually withdrew from Dubai, the first Premier-5 event of the year.

The Swiss, however, reached the second week of Indian Wells for the third consecutive year, only to retire against Karolína Plíšková due to wrist injury.

At Roland Garros, Bacsinszky defeated Sara Sorribes Tormo, Ons Jabeur, Madison Brengle, Venus Williams, and Kristina Mladenovic to qualify for the semifinals.

[24] At the St. Petersburg Trophy, Bacsinszky was defeated in the first round by eighth seed and eventual finalist, Donna Vekić.

[28] During the Fed Cup tie versus the US, Bacsinszky was defeated in both of her rubbers by Sloane Stephens and Sofia Kenin.
