Runner on 3rd only (1 out vs. 0 out)

When a runner gets to 3rd base, the 3rd base coach must be keenly aware of how many outs there are. The number of outs determines exactly how aggressive the runner should be.

If there are 0 outs, the 3B coach or manager should more than likely have a "on the ground up the middle" read on. This says that you do not want the runner breaking for home plate unless the ball is hit up the middle past the pitcher to the SS or 2B. This baserunning read is predicated on the corner infielders being in an "in" position. If the infield comes in, then the read must be "make the ball go through." If the batter grounds out, you still have a runner at 3B with 1 out. This is no time to be aggressive with a runner in scoring position.

If there is 1 out, it is definitely time to be aggressive. Many times, this scenario would imply that the "contact" play is on. This means that the runner breaks for home when the ball is hit on the ground. The idea here is that you are running out of scoring opportunites and we want to be aggressive with trying to score. If the ball is hit to a corner infielder or the pitcher and there is a play on the runner going home we say "out by a lot, get in a rundown." This rundown is very important in a 1 out contact play.

The runner must stay in the rundown long enough for the batter to sprint to 2B. If the batter is sprinting out of the box and he gets into scoring position with two outs then we still have a runner in scoring position with two outs. It is very important that the runner on 3rd understand these principles. You absolutely do not want him running into an easy out at home and stranding our batter at 1st base.

If you understand "risk vs. reward" scenarios and you understand "out by a lot, get in a rundown" choosing the right baserunning read isn't too difficult. You simply play percentage baseball.
