Yeah, it looks like a brown snake- or "worm" snake. They're harmless. It might not be a baby- they're not very big as adults. They eat worms, so you will find them in dirt or places where worms live, since that is what they like to eat. They make pretty good pets and you just need to feed them worms every week or so. Plus they never get more than 18" or so long, so no worries about them getting too big.
