Did a little looking: Cricket bats are about the same length as a baseball bat, weigh between 2-3 lbs, and come in short handle and long handle versions. I'd use the same stats for D&D and similar games.
However, given their shape, I wouldn't be surprised to find that, if used as a weapon, hits with the edge weren't a bit nastier due to the concentration of the force...but it wouldn't be as durable- ash is @2x harder than willow. Hickory is nearly 4x harder.
