Coco Vandeweghe has caused uproar after a ‘petulant’ act during a warm-up at an ITF USA event.
The former World No.9 American was up against Ekaterine Gorgodze when play was suspended due to extreme heat at one set all.
When the players returned, Vandeweghe appeared perturbed and didn’t want to warm-up.
The American was hitting the ball very lightly back at Gorgodze and didn’t appear to care where it landed.
The rules state a player can face a post-match fine if they do not follow the rules during a warm-up, but it is unclear whether Vandeweghe had initially refused to take part due to the heat.
Tennis player Pam Shriver responded to the video of Vandeweghe and said she had refused to warm-up after her opponent took too long to return to the court during a match at Wimbledon.
Fans were left gobsmacked at Vandeweghe’s behaviour and slammed the American after she went on to lose the next two games with very little effort.
Leading tennis reporter Ben Rothenberg said he hadn’t seen such behaviour during his time covering tennis.
