As a footnote, I never like to hear a high school player (or his parents) talk about how he's still eligible to play at the age grouping a year below his class year.
First of all, ever since the aging date got moved back from August 1 to May 1 some years back, that is a claim that maybe 35-40% of players can make, so you're not saying anything noteworthy.
Worse, it comes across as some excuse for non-performance or at least, for less-than-stellar performance. "Sure, Joey's hitting .450 and Billy's hitting .280, but Billy is only a 14u kid really."
That kind of talk is for parents in middle school and younger ages. Once you get to high school, all anyone cares about is your class year.
