One commentator was heard gasping as they watched Swiatek's outburst unfold, before another labelled the act "terrible".
The reaction sparked a hostile response from the crowd as a chorus of boos began to echo through the arena.
It was not the first time the boos were heard in the venue during the match as it seemed to be a routine occurrence ahead of the final set for Swiatek.
The 23-year-old complained to the chair umpire following the incident about alleged movement from the ball kids behind her while she was waiting for Andreeva's serves.
No evidence was noted by the umpire to confirm Swiatek's claims.

Andreeva will meet top seed Aryna Sabalenka in the final on Monday morning (AEDT).
"I don't know why I felt so much confidence," Andreeva said after defeating Swiatek.
"I felt like, 'I'm going to go and play the tiebreak like it's the last tiebreak of my life'.
"I just went for all my shots. My serve was great, just felt super comfortable and super confident."
