After a high school game last year I was chatting with the opposing coach. He told me he had two freshman on JV with better velocity than any of his varsity pitchers. He said they're better served on JV for the season developing command and building confidence dominating JV ball rather than playing for a mediocre varsity team. Then he smiled and said, "We'll be back next year to kick your son's team's tail with these kids." I don't know if these pitchers were called up later in the season. We played them in the second week.
