re: First baseman had wrong foot on the bag restricting his ability to stretch for the throw

Jones was fine, in good position to receive a throw. Look at the throwing lane presented... Milazzo is on the grass halfway between the mound and the baseline.

The problem is Milazzo threw it sidearm and rushed, and it sliced to the right. See how far over it crossed.

It's hard to tell with the still image, but that's the ball to the right of Jones' glove, right at the white chalk baseline.
In theory, Jones could have caught it, IF he had set up to take the ball in foul territory. Which IS the normal way to take it from the catcher, on something like a 3rd strike in the dirt. But the fact that Milazzo was halfway to the pitchers mound makes for a different angle, and the throw should have been at the bag or inside.

I do think maybe Jones could have stood with his right foot on the bag to give a better angle, stretching towards the mound. But that wouldn't have helped on Milazzo's throw.
