Did you see the video? He didn’t even look like he was angry in the least...Just using his racket to send the ball back which I guess the line judge didnt see coming and then the judge took a fall right out of FIFA or the WWE.
Take a fall, collect the cash.
The alternative is dangerous carelessness, which does make me feel a bit better, but that, too, deserves consequences. But you’re right, he wasn’t stomping around in a childish rage. The consequences for that, had that been the case, ought to have been a lot worse.
It did not seem intentional to me. An underhand lob back to the judge; if it was out of frustration and intentional, it would have been overhand and the judge would be in serious straights.
It was a setup.
