"Beat the force!"

This is a common baserunning cue for a runner at 1st base with 2 outs.

The 1B coach or the 3B coach should remind the runner that you want the infielders to throw the ball across the diamond to record the third out. You don't want the infielders to take the easy 3rd out at 2nd base. So, you yell to the runner to "beat the force."

Here is what you expect.

You expect the runner to get a decent secondary. When the ball is hit you expect the runner to sprint full speed sliding feet first into 2B. Sprinting full speed is the key so that the infielder feels compelled to record the out by throwing across the diamond.

Now, there could be some other interesting dynamics with beating the force. Let's say it's a 3-3 game in the last inning. Runners are on 1st and 3rd with 2 outs. The 3B coach exhorts his runner to beat the force. In this situation he should literally run through the second base bag into left field trying to beat the force. Don't slide and slow down. Run through the bag. If the 4th run scores the game is over.

Man on 1st, 2 outs. "Beat the force."
