What has to happen to be awarded a single base or two bases

[Whowefoolin]

Usually anything that happens with a pitched ball is a one base award.

Anything thrown or hit is 2 bases.

So a ball goes into dugout on a pitch...1 base.

If a thrown ball goes into dugout...2 bases.

Basic, but hope this helps. And, yes there is a difference between a pitch and throw. From the mound is a pitch.
