Born in Switzerland to Slovak parents at a time when Slovak-Swiss player Martina Hingis was one of the best tennis players in the world, Bencic began playing tennis at the age of two.

By the time she was 16, Bencic became the No. 1 ranked junior in the world and won two junior Grand Slam singles titles at the French Open and Wimbledon. On the professional tour, she made her top 100 debut shortly after turning 17. Her first big breakthrough came at the 2014 US Open, where she became the youngest quarterfinalist since Hingis in 1997. Bencic won her first two WTA titles in 2015, including the Canadian Open where she defeated four of the top six players in the world. She then made her top 10 debut the following year while still 18 years old.
