But you can also look at the two greatest players of all time, and see that racquet breaking and showing an extreme level of frustration doesn’t help. Roger famously used to be a blizzard of emotions on court, then took action to eliminate that behavior. I can remember only one time when he has smashed a racquet (Miami, 2009) in the last 15 years. And Rafa has never smashed one. Of course they have shown frustration at bad decisions by umpires, and other incidents, but they get over them quickly, and move on.
Tsitsipas, Zverev, Norrie, etc. can smash as many racquets as they want (and pay the fines), but they need to realize this behavior is ultimately only hurting them. If they learned to reign in their emotions, their results could be better.
