Able, Baker, Charles, etc is fine, but things do get confusing when we mix 'n' match baseball baserunner numbering conventions with softball.
This is a softball board. Simple as that.
R1 is closest to home. R2 is next closest. R3 is always on 1B (bases loaded). Batters /substitutes/ etc. are numbered from the beginning of the situation / inning as necessary for clarity.
It is annoying (and sometimes confusing) to have baseball numbering used here.
New posters or visitors from baseball-land can be forgiven.
Stubborn old hands... well, we'll forgive you too, so long as you put up with some grumbling / correction!
