A, B, C. Slots

[Chess Ref]

I see this used all the time and I have some questions but first I need to get this terminolgy down.

A slot = foul territory 15-18 feet behind 1B. Correct ?
B slot = behind and to the left of 2B correct ?
C slot = behind the shortstop Correct ?

I'll post my questions after i nail these down .

Thanks for the feedback......
