What situations dictate cutting down a runner's lead at 3B?
Ball in dirt - probably not going to score
Ball to backstop - probably will score
Fly ball with less than two outs - lead doesn't matter
Squeeze - so many things to eliminate this
1. Have pitcher vary deliver to plate and outright hold the ball until time is called
2. Pitchout on a break to the plate - if he has a big enough lead then you can back pick with catcher throwing to 3Bman
3. Go from stretch and not windup
4. Run an actual pick play with 3B or SS
5. Quick step off to see if a squeeze may be on
I'm forgetting some but my point is I don't know of any real situation where holding a runner on at 3B is worth the risk / reward that redbird is talking about.
