There was an era where high school prospects were hidden. Fifteen of the sixteen teams might have no idea who the kid was. He signed for a large bonus forcing him to play in the majors his first year. This was back in the 50’’s and 60’s I was too young to know the details. Maybe Bob (Consultant) could elaborate.
But just going back to 2002 there was a high school kid in Maine throwing 90 soph year. He lived in a town of 20,000 attending a high school with 250 in his class. No one (scouts) had heard of him. He went to a showcase in North Carolina. He left with his choice of colleges. He choose one of the top baseball programs in the county. He never got there. Mark Rogers went from a kid attending high school in a small town in a small state to 5th pick in the draft. He made it to the majors a couple of times. But arm problems held him back.
In this day I wonder if any kid at any age throws 90 and all of organizational baseball doesn’t know about him.
Speaking of prospects, there’s a good show on MLB Network, The Sounds of Baseball. It’s about the best announcers, Vin Scully, Jack Buck, Harry Carey, Bob Uecker and Joe Garagiola. Garagiola jokes he wasn’t the best player on his street. Yogi Berra lived across the street.
