Harry Potter author JK Rowling has joined numerous social media users in criticising a cartoon by The Sun Herald cartoonist Mark Knight depicting 23-time Grand Slam winner Serena Williams losing her cool during the US Open Women's Final.
The cartoon is a spin on the moment Williams smashed her racket, which resulted in her second of three code violations as she was downed by Japan's Naomi Osaka 6-2 6-4.
Osaka's maiden Grand Slam victory was overshadowed by Williams' antics, which has seen chair umpire Carlos Ramos thrust into the spotlight.
The cartoon exaggerates Williams' anger and shows the tennis star jumping up and down on her racket, with a pacifier nearby.
In the background, a character depicting Osaka is told by the umpire: "Can you just let her win?".
JK Rowling picked up on the social media furore over the cartoon and said it reduced Ms Williams to "racist and sexist tropes".
