Why does " sandbag " as a verb mean treating unfairly or harshly? Is there some allusion to its figurative meaning?

 

[Charlie Bernstein]

I usually hear it used to mean hurt unexpectedly: "I thought I was doing a great job, so I was really sandbagged when I got fired."

To learn where words and expressions come from, Google it followed by the word derivation, like this: sandbag derivation

So try that. And look at several answers!

Do they know who he is? "

Please note my corrections above.

Don't put a space after opening quotation marks.
Don't put a space before closing quotation marks.
Put a space after the words "season" and "episode", before the number.
Don't put a space before a comma.
Don't put a space before a full stop.

I've wondered about the use of sandbag too.

I've heard it only in the last few years or so, always from AmE and usually young speakers. The Urban Dictionary says it's used like this:

https://www.urbandictionary.com/define.php?term=sandbag
https://www.urbandictionary.com/define.php?term=sand bagging

However, I'm not completely convinced that the entries above cover the ways I've heard it used, and I can't properly understand this use in the context given in post #3. What's more, Charlie Bernstein seems to have a completely different understanding.
