The First

[KCGHOST]

Walt Henline was the first ML umpire to do what??

[Ubiquitous]

First ML umpire to have hit 3 homers in a game? Or is it the first Umpire to throw Jackie Robinson out of a game, which would probably make him the first umpire to throw a black ballplayer out of a majore league game.

[Utter Chaos]

The first umpire to kick a fielder in the head while simultaneously stepping on a runners back.

[KCGHOST]

I've heard of players hitting three homers in a game but have never known an umpire to get an at bat even.

He was the first umpire to eject Jackie Robinson from a game.

How bout Bill Dineen? He was a former ML player who had got some at bats, I think.

You are misunderstanding my answer. With the exception of things from the early days and a rare player filling in for an umpire an umpire has never batted. He may have while he was a player, but not after becoming a umpire.
