By Position:

	Pitcher backs up the plate.
	Catcher steps up to command his infield and protect his team's home.
	First Base lines up for cutoff to the plate.  Be ready to fire the ball back to third if the lead runner over turns after your OF does it's job.  If the runner is going to reach the plate, your SS should communicate that to you.  In that case, be ready to surprise the new lead runner.  But only throw the ball if you actually have a play and you know your teammate is ready to receive such a daring attempt.  Be ready to move back to your bag if the play is shortened by your fine defense.
	Second Base is the cutoff to the left side.
	Third Base covers the bag.  Know how to play 3rd.  Learn all you can about all the possibilities.  Be prepared to act quickly.
	Short Stop covers second.  Remember your alternate cutoff assignments.  Have a feel for how the play is developing, and revise your assistance accordingly.  (Playing SS requires superior intelligence so the phraseology here shouldn't trouble you.)
	Left Field backs up 3rd.
	Center Field rushes to ball.  Take charge.  Show your speed.  Help your RF if he reaches the ball first.  Let him have it if he can because he is likely in a better position to throw.  Your throw will probably go toward the plate, either through 1st or 2nd.  Use your cutoffs unless the ball is hit shallow and you are running in to scoop it.  Listen for your team's help.
	Right Field rushes to the ball.  Help your CF if he reaches the ball first.  Use your cutoffs.  Remember, you are in a better position to throw than your CF who has to turn, so don't give up on the ball until he calls you off.

The Team communicates.
