5.05 (a) 5-9 all seem really focused on situations that could happen in older parks that don't exist anymore (250 feet?), and Wrigley (are there any fences that are so poorly built that a ball is going to go under or through them?).
5-9 should be rewritten so that automatic doubles that make it over the fence in any capacity -- even on the bounce and even off the Renfroe -- are
homers.
To my mind, over the fence is over the fence (unless it is hit by that yahoo Kiermaier!). All the other stuff -- stuck in the fence, going under a door, whatever -- should be actual 'ground' rules based on the parks and then maybe automatic doubles just so there is a blanket position for the umps.
Such a rule change with start the great era of warning track shenanigans, as teams would either put in super bouncy tracks or sand pits depending on their assessment of the competitive impact.
Also, if you can hit a baseball through the fence, that is some serious Roy Hobbs shit. You should get the homer!
