Son plays 13u. Lefty, tall, long arms/legs can't connect and getting lots of K's. Video taped his swing using coaches eye app slowed it down. Appears he was leading with his back elbow and casting his hands out. Corrected that but still can't connect. Hoping I could find someone who can take a look at the video or suggest who can look at the video and help correct this. Unfortunately all the good hitting coaches in my area are booked (already tried that route). I can help with drills and such but don't have enough knowledge to make sure we are doing the right thing. Any help much appreciated he is quite frustrated and driving me nuts!
