1st and 3rd situations - Throw to 3rd
This can be a good
play when the runner on third is an aggressive base runner. As the catcher
catches the ball, he simply fires the ball to third instead of second. If
the runner is trying to get a good jump from third and gets too far from
the bag, it's an easy out.
Some coaches have the catcher fake a throw to second and then throw to
third. This rarely fools anyone and simply throwing strait to third will
give you a better chance of getting the runner.
