Seeking help on a gb injury reading

Don Hoak grounds out with runners on first and third. The runner on first is out, the runner on third holds. What kind of gb is this? Is this a gbC? If so, why doesn't the runner on third score? Can that happen if the infield is in? (Either way, he is outperforming a bad card, which is a whole other question.)

Thanks for any clarification.

I can't help with the whole mystery aspect of the game, but I do know a runner can be held with a ground ball C if the infield is in. Hopefully someone else can give you clarification.

Thanks! That's exactly what I need to know.
