Kimberly Birrell’s injury history
Kimberly Birrell has struggled with serious elbow injuries throughout her career, including multiple surgeries that sidelined her for long periods between 2019 and 2022. Those injuries significantly interrupted her rise on the WTA Tour.
In 2016, shortly after making her Fed Cup debut for Australia, she suffered a right elbow injury that forced her to miss the remainder of the season. She later underwent elbow surgery while trying to recover fully from the issue.
The most difficult stretch came after her breakthrough performance at the 2019 Australian Open, where she reached the third round and defeated players such as Donna Vekic and Paula Badosa. Just as her career appeared ready to take off, recurring elbow problems returned and severely limited her schedule.
According to the ITF, she played only four tournaments between July 2019 and January 2022 because of two separate elbow surgeries and lengthy rehabilitation periods. During that period, she admitted she feared her career might be over.
In a 2023 interview with the ITF, she described the recovery process as “hellish” and revealed she was uncertain whether she would ever return to her previous level, especially with concerns surrounding her serve after surgery.
By rebuilding her confidence through ITF tournaments and gradually returning to WTA events, she managed to climb back into the Top 100 and later reach a career-high ranking of No. 60 in 2025.

Their partnership has become increasingly important during Birrell’s resurgence on the WTA Tour. After years of injuries threatened to derail her career, Pratt helped guide Birrell back into elite-level competition.
Birrell herself has repeatedly praised Pratt’s influence on and off the court. In an interview with Tennis Australia in 2025, the Australian player said she had been “so lucky to have Pratty in my corner” throughout much of her career.
