At 15, unless you're 6'2", most HC/RC will not pay much attention. Unfortunately size is needed to pass the eye test of many HC/RC. I would concentrate on getting stronger and faster. If there are HC/RC at 15U PG tourneys, most likely they are there looking at pitchers. I would concentrate on finding opportunity with a good travel team and to continue to improve skills while showcasing them in front of all divisions. Eventually you will know where your 2022 fits in by which schools/divisions are showing the most interest. There is plenty of time to get noticed as a 2022!
I have mentioned this many times on the board. The 6'2" 210 kid will get every opportunity to prove he can't play and the 5'9" player will get some opportunity to prove that he can play. Unfortunately it is the reality of college baseball.
