The Eyeball Scout is loathe to make many judgments on a pitcher’s major league debut, as often control, command, and even the action on the pitches, are often skewed by the unique adrenaline and bundles of nerves that accompany debuting pitchers to the mound.
For example, in Daulton Jefferies’ debut he overthrew his changeup and it became a 90MPH meatball that resulted in a couple monstrous HRs. No one could have predicted that once he settled down Jefferies would go on to be a pitcher who ... served up HRs like they were going out of style. Wait, that didn’t work.
