Thankful that my dd’s 18U team worked on it often. She was playing 1B the other day in her college game - ground out to 3B with throw to 1B (no play at 2B) and runner who went to second kept going 1/2 way past 2B. Dd immediately began to run at her after she got the out at 1B. Girl just froze - dd tossed to 3B and then they tagged her out after a quick rundown.
That’s the key - running at the baserunner. If my dd just threw to 3B or to 2B runner most likely would have been safe. Running at them causes confusion and many times they freeze.
Running at them also shortens the throw, making it more likely to get an out.
So why no pump fakes? I've heard the reason before and I believe it, I just can't remember it. Is it because it just makes the play go too long?
