Squeeze or Sac?????

A sac bunt is usually with a runner on 1st, runner on 2nd, or runners on 1st and 2nd. The idea is to get a bunt down that advances the runner(s) and you sacrafice yourself to do it. Usually with a strike you only bunt the pitch if it is a strike. Sometimes a coach will tell batter to bunt any pitch close so the element of surprise is there.

A squeeze bunt involves a runner on 3rd (runners could also be on other bases) when the pitcher starts his delivery the runner on third breaks for home like a steal. The batter squares to bunt and has to try and bunt the ball no matter where the pitch location is and as long as the bunt is on the ground and fair the runner usually scores pretty easy.

Same thing that dueter said.
If theres a man on 1st, most of the time you will bunt to first to get the guy over which is a sacrifice bunt.

Man on 1st and 2nd you bunt to third getting the 3rd basemen to come up and field the ball, letting the runners advance.. yet, another sacrifice bunt.

When theres a man on 3rd when its probably a close game..(with 1 out) you will bunt the ball. YOU MUST TOUCH THE BALL, FAIR OR FOUL..GET IT DOWN! if you dont fulfill your duty..then the runner is out.

Dont Try..
You Already Lost..
