My son had a D3 coach see him at the Arizona Fall Classic in October of 2018 and recruited him because he liked his energy between innings and how he led his team OFF the field in the dugout. He only watched him for TWO innings the whole long weekend and has not stopped calling even though my son signed in February of this year. That school is in the D3 World Series starting on Wednesday. The coaches their must be doing something right.
Do high school stats matter? It depends. I have seen pitchers get their D1 scholly's dropped based on overall performance and mental stuff. I have heard position players getting calls telling them that they may have to play outfield vs infield once they arrive to school. But I have not heard any stories that attribute bad statistics in high school to recruiting.
