A lot of these new coaches would probably advise against it but I would tell him to shorten up his swing a little and just try to get a single. Once he does that I think he'll get more comfortable and get going. And NO I don't want to revamp his swing. Just trying to get him to focus on the ball and not try to do too much.

If it's the same pitch and location then he probably needs to see it on video and then make an adjustment based on what people are doing to him.

That's my two cents.
