Seems like the routine move to me, for this situation; this play fits this situation because of his stack size. Yes you don't have any reads, but most of the time here you're ahead of the hands we can put him on.
Also, like you mentioned above, he's short stacked, it isn't like you're going to be committing any more money to the pot, you're getting great odds
of having him beat or just taking it down here by making this play.
I probably make the same play given the situation. If he has a set, tough break, but this is still the right play to make for this situation.
