Forget on line calculator

All you need to remember is

image size = subject size X focal length / distance

Image size is your sensor size, assume 2 meters for a standing person.

Shooting distance you can either figure from the ball parks dimensions, 325 feet typically at the foul pole and 400 in straight away centre field, or usually on line the stadium map gives you dimensions.

If you are going to a ball park and want to be relatively inconspicuous, take a Q, given the crop factor the Q plus M135 is like a 600/3.5. You don't get the same effective range with anything else.

IMO a k1 is useless, unless you take a lens they will never let you past the door with.
