A former prodigy on the junior tennis circuit, Bacsinszky semi-retired from tennis in 2011 at the age of 22 following a major foot injury. After playing a qualifying match at the 2013 French Open, Bacsinszky made a full comeback onto the WTA tour in 2014 with success, winning her opening round match at three of the Grand Slams and upsetting world No. 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. Bacsinszky received the WTA Most Improved Player of the Year award for her massive singles rise that year. She once again reached the semifinals of the French Open in 2017. She also reached the quarterfinals of Wimbledon in 2015, and of the French Open in 2016.
