#1) Superman smacks one so hard it flies out of the park and completely around the world and back into the stadium where Peter Parker catches it in left field.
Is it a home-run or is Superman out?
#2) Next time up at bat Superman smacks another one out of the park, assumingly around the world again. But this time Reed Richards stretches his arm and hand out, and 500 miles away catches the ball. Another home-run or is Supes out?
Following the 1st rule, would example 2 not be a home run also?. The ball has long passed the imaginary 250 foot line, and the batter shall have rounded bases and made home.
The point of the 250 feet is that it’s a home run only if it goes over a fence or wall that’s more than that distance from home plate. A fly ball isn’t automatically a home run just because it goes more than 250 feet.
It does sometimes happen that a fielder catches a fly ball after it goes over an outfield wall. This shows up in the nightly sports highlights several times a year. The batter is out in this case.
Also, it doesn’t matter whether Superman can make it all the way around the bases before the ball is caught. This is not a timing play - the batter is out if a fly ball is caught regardless of when it happens relative to anything else.
There is an assumption that a fly ball that goes out of the park is a home run because it can’t be caught by fielder with both feet inbounds. Since the ball travels around the world in this case, it has to be going slower than escape velocity, which means it will take at least an hour before it returns to the park and is caught. I think it will be declared a home run before that time, and the ball will no longer be in play and can’t be caught. Thus it will be scored as a home run in the end.
And how can we be sure that the ball that returned to the park is the same ball that was hit out of the park? What if the ball only went as far as Japan where some other superhero hit another ball back this way?
Not to mention that, as far as I understand it, all plays are final once the next batter has come to the plate and either put the ball in play or makes an out himself.
