Melbourne - Coco Vandeweghe has been hit with the largest fine of the 2018 Australian Open so far - a A$10 000 (R97 400) penalty for unsporting conduct for screaming an obscenity at her first round opponent, Timea Babos.
Vandeweghe said after the match that she was irritated by what she described as excessive celebrating by her Hungarian opponent during their match.
The 10th-seeded Vandeweghe was assessed a code violation for the obscenity and delay of game for insisting on eating a banana during a changeover, getting docked a point in the second set of her 7-6 (7/4), 6-2 loss.
Borna Coric has received the largest fine thus far in the men's draw - A$5 000 (R48 700) for shattering his racket during his first-round loss to John Millman.
