In 2019, Andreescu won in Indian Wells and the Canadian Open at home before going on to lift her maiden Grand Slam title at Flushing Meadows. The 22-year-old Canadian rose to a career-best ranking of fourth the same year but later struggled with injuries, never able to recover reprise the same form again. Andreescu, who has slipped to 53rd in the rankings, returned to the Tour in Stuttgart in April after a lengthy break to deal with mental health issues and revealed that she was close to quitting tennis.
