His name is Viktor Troicki and he lost his mind after a call from the chair umpire. He even fired a tennis ball into the crowd during his meltdown. The tantrum had a momentary pause before picking right back up at the end of the match.

Because at the end of the day it's tennis and nobody gives a shit about tennis.
