We don't have hindsight on Stephenson yet, but he possesses octane that neither Bailey nor Cueto ever boasted. In fact, he's got two pitches better than anything Bailey or Cueto throws. He's searching for control a bit at the moment, but he's still carrying an eye-popping 10.9 K/9. It is no slight on Bailey or Cueto to note that Stephenson may be the better prospect. The kid is a rarity, a once-in-a-lifetime prospect. That's the kind of arm he's got. It could all go wrong, but Stephenson's ability is off the charts.
