Bluedog, the kid asked about dropping his hands and questioned whether he should fix what's not broke as he's hitting fine. Having looked at his base which appears ok...in keeping it simple and bearing in mind your dealing with a still pic...as long as he's loading properly and getting his hands in proper position he should be fine.
Considering the varying degree of stances of hitters at the MLB level...i.e. completely upright to very crouched... hands very high over head to very low waist level...hands way out to tucked in tight..base fairly narrow to extremely wide...I'd say stance is more a matter of personal preference...Just don't see the similarities or connection between stance and success as a hitter but would appreciate hearing your take as to why the stance is hugely important as I may just learn something new.
Thanks.
