As everyone knows, Djokovic and Carreno Busta played at the US Open in 2020 and Djokovic was disqualified after hitting a lineswoman. At this point, Carreno Busta was serving for the first set. My belief is that even if Djokovic had not been disqualified, Carreno Busta would have won the match anyway. That's why Djokovic lost his rag, things weren't going his way. If he had the match under control, he wouldn't have made an error in judgement like that. So then, I was pleased to see Carreno Busta win the bronze medal match at the Olympics the following year which gave vindication that the US Open wasn't merely a fluke, a freak event.
