He's not thinking about arm slots, I assure you. He just does not, will not, and I'm not sure cannot get his arm up. Coaches have yelled at him, fathers have yelled at him, I'd guess that if I listened hard he's yelled at him. He just throws low. From the time he was 7 until now 14 he's thrown low. I gathered from the description of the motion on the ball that his hand is to the side, because that's exactly what the ball does--it cuts away from right hand batters.
The coach isn't a bad coach. He caught through through AAA and he coaches at that elitist University in, not of, Houston. He's sorta related to someone here, though I can't recall who, except it's someone who can't keep his pants up when he's around BudGirl. Basically he said there's nothing forced about it, it's an easy motion for him, he throws strikes, don't change it. Me, after 7 years, I'm worn out trying to change it, so his verdict made me happy.
Honestly, I think I'm more likely to get him to quit baseball than to get him to get his arm up. Maybe his high school coaches will take care of one or the other. More power to 'em.
