Ground Rule

So would you have had an issue with calling balls home runs that would go into the baskets in Wrigley Field and other stadiums in the 70s and 80s?

I would have but if it's good in MLB it's good at Kokernot.

To further express my chagrin and naivete I submit this MLB ground rule:

Discovered tonite while watching a HR called back upon review at that stadium. It should have been a live ball, per the field ground rules,  but the unofficial (having in mind another thread) HR signal had been given making the ball dead upon the twist of the wrist. So after review batter-runner place at 2B. Not a book rule double I think but just reasonable placement of him after review.

In discussing my Kokernot ground rule at the plate meeting one of the coaches said if he hits it that far why not give him a HR. The same question could be asked at a Chase Field plate meeting.

So much for the rulebook language of leaving the playing field in flight. But how does MLB decide where to put the yellow line.

In most cases, the "batter's eye" is a structure that is separate from the wall.  The line is placed at the top of the wall.

 

It's just like your scoreboard example (except the batter's eye is "plain" and the scoreboard has "numbers."

I do agree that if umpires designed stadiums / fields, there wouldn't be any yellow lines to have to judge.  IT would be much easier to tell a homerun from a ball in play.
