Aryna Sabalenka narrowly missed a ball boy as she threw her tennis racquet on court at the Wuhan Open on Saturday, 11 October.
The world number one was in pursuit of a fourth successive triumph at the tournament in China, but lost her semi-final to Jessica Pegula.
Reacting to an error, Sabalenka threw her racquet towards the players' benches, almost hitting a nearby ball boy.
She immediately held her hand up in apology towards the ball boy and a nearby camera operator.
Sabalenka was issued a warning, a Sky Sports commentator said.
