I could not agree more as to wanting him to do it all the time if it’s a skill, but there is enough evidence that it MAY be something that he’s doing possibly even subconsciously. It could be pitch selection in that situation, or compete and utter luck, or some other variable. It just seems as though there could be something unexplainable (as of now) there when the sample size gets big enough. I think a deep dive into it would be warranted to see. You may be right in that it’s a stamina thing, and he’s better suited for the pen. I would live to see someone way above my pay grade do that deep dive and see if there’s anything meaningful there.
