Hard to comprehend a kids PR number vs. their K, ERA, H if they don't match up.
Not sure how these relate. High speeds with no movement will get k's, low era's, and low hits if the competition is week. Against good competition, speed with no movement can get rocked. See girls in high school all the time that have great numbers in school ball because they don't play good competition. ERA and hits is only as good as the scorekeeper. My kid's school numbers are worse than several on her travel ball team, yet she will pitch more with the travel team than they will. Plays against a whole different level of talent than they do during school.
