I have 3 boys and all have played a good bit of baseball and they all had their own path.
My oldest was pretty mid, but always loved it. Around 13, he grew a bit and got a taste of a higher level of ball and it drove him. He started working his ass off and from HS baseball cut day freshman year to tryouts sophomore year, he put on 45 pounds of muscle through just his own drive (and teenage metabolism). He went from a kid who probably had no business playing any kind of competitive ball to being a spot starter and pen arm for a team that finished in the top 4 in the biggest class of NC HS baseball.
My middle was not even mid most of the time coming up and when they hit the ages where kids started pitching, he cared less and less and practiced less and less. Totally cool - he’s much more of a music & theater kid and is very, very happy away from sports. He’s now a HS senior and hasn’t had one regret about his path.
My youngest is almost 14. He’s a lot like his older brother, probably a little naturally bigger/better at this age, but he also has a lot of interests that align with the middle, so it’ll be interesting to see what choices he makes in the next couple of years because if he wants to play varsity ball in our HS (biggest in NC), he’s going to have to put in a shit ton of work that will probably pull against some of those other interests. I welcome him making his own choices and making his own path.
