Fognini pulled a Stevie
Fognini kept shouting the whole tiebreak that Caruso was being "f**king lucky" for saving the first few match points. That distracted Caruso and he lost.
The full discussion after the match :  
Fognini: You have been f**king lucky, you should apologize.  
Caruso: What are you talking about? 
F: You won four identical lucky points 
C: What are you talking about?! 
F: Can’t I say you have been f**king lucky? 
C: I didn’t dare to say a single word in the whole match 
F: I said something because you called for it 
C: I didn’t dare to say a single word in the whole match, enough now 
F: Can’t I say you have been f**king lucky? What’s the problem?! 
C: You can do whatever you want… 
F: So why are f**king break my balls now? I said you have been f**king lucky, if I’m wrong saying it. I’m wrong, don’t attack me 
C: I didn’t attack you. I’m telling you it’s not the way to behave cause I didn’t tell you a single word. Let’s say, I didn’t expect it from you 
F: What did you not expect? I told you have been f**king lucky, you didn’t like it, what should I say? 
C: It’s not the way to do it.. 
F: Why? What’s the problem  
Then they got separated
