Baseball is almost unwatchable with the umpires as the umpires have way too much power and should be dialed way back to make the game more interesting you cannot even challenge their balls and strikes you get thrown out no one pays to watch the umpires
If you didn't make arguing balls and strikes an automatic ejection, you're liable to have an argument over balls and strikes every half inning.
You're allowed to argue any other call, and oftentimes umps will take a little lip from a player or manager about a ball/strike call they didn't like without an ejection. The Rendon ejection was nuts though. MLB umps absolutely have the biggest egos among sports officials though.
