Anyone with his results is a potential prospect worth a deeper look.
Results, especially in the lower minors is a good sign, but not enough to hang your hat on.

Same way if a hitter is raking, see his BABIP, check his BB/K ratio, his ISO, etc.
Watch his bat speed, plate discipline, ability to use the whole field.
Don't depend on one or two raw numbers, velocity, exit velocity.
