Base stealing question

With runners on first and third I've noticed that HAL often tries to steal second. The success rate has been very poor and it usually kills a promising inning.

It doesn't seem to be part of a double steal since the runner on third always stays there.
Base stealing is set to extra conservative and hit and run is turned off for all hitters.

Is there something in HAL's logic that explains it?

HAL Logic great Oxymoron!
