What planet are you from? That has always been the case in all aspects of life, not just in pro sports. Clownga is just bitter because he is not good enough to take advantage. Umpires shitting their pants when a player looks at them is a privilege that was earned by the big 3. They all were journeymen at some point. When Clownga wins multiple slams, he can also benefit, until then he's just a butthurt scrub who come off as a whiner.
The thing is that no players should get preferential treatment from umpires.
Telling Clownga to become a Top 4 player is irrelevant.
