Run or no run

[MT 73]

I cannot count how many times I have been told that if a runner is thrown out at first base while trying to return after leaving early on a caught fly ball that it is a force out.
Thankfully this exact situation is spelled out in OBR under the force definition--where it clearly states that this is NOT A FORCE.

Its because its the one other out you see a lot on a runner thats not a tag play. Most people associate tag and force with how the out is made, not really using those terms to apply to the runner being "forced to run" or not. So they equate any out that is not a tag as a "force" but part of that is because its really not so much an action/live play although it happens that way as it is an appeal play.
