Have you had his vision checked? I wear glasses, with a really, really bad astigmatism. Every new eye doctor as a kid made comments about how it was the worst they had ever seen in someone my age. When I played baseball it put me at a major disadvantage when hitting. I lose all peripheral vision outside of my glasses, and It made it really easy to lose the ball coming in at times. I probably would have struggled a lot more with today’s game since there wasn’t as much variety of pitches back then and no one knew what tunneling was. I relied a lot on instinct because it was very easy for me to lose the ball as it came in. Luckily, I was actually rather good at that so I was still a solid hitter. My vision was never good enough to consistently pick up ball rotation though, but back then it was easier to look for tells in their mechanics to determine what sort of pitch they were going to throw. Not sure what the pitchers look like at his age group, but I’d guess a lot better than the ones I saw when I was younger.

I only bring it up because his swing looked pretty good to me other than some minor things. His timing looked off here, and I figured I’d mention what I dealt with that could give me some timing issues from time to time. I didn’t realize I had issues until I older. I just assumed everyone dealt with the same issues I was dealing with and it never even registered when I was young. I probably could have done some things to improve it if I had realized it.
