I suspect that baseline and basepath are often thought of as being one and the same. Which they're not.
Bonus geekery:
(1) You can be called out for interference if hit by a thrown ball even if you are in the running path.
(2) You can be called safe if hit by a thrown ball even if you are out of the running path.
Charlie Williams, one time umpire fired for incompetence and for being just an outright asshole too, was infamous for calling a runner out if the ball hit them on a throw. Didn't matter where the runner was going, first, second, third, home... didn't matter. Didn't matter if you ran on the baseline or basepath to said bases, if the ball hit you... Ol' Charlie would call you out and then if you questioned him, he would toss you out.
Worse umpire I've ever seen work a game, not matter where he umpired. But the calls on runners was always an adventure with Williams. So now we have Angel Hernandez to take his place, although I suspect Angel at least knows not to call a runner out just because a thrown ball hit him.
I think. I hope so.
