Sixteen year old son has recently resumed playing baseball after a six month hiatus caused by ACL/MCL knee surgery. He's been struggling hitting-wise and has developed some bad habits/muscle memory that has resulted in poor performance, strikeouts, meek grounders, etc...at the plate. I see what he's doing wrong and I feel it is very common, perhaps the most common hitting flaw. He can't make the correction though and just gets frustrated and irritated with me when I tell him what he's doing wrong. Before I say what I feel he's doing wrong I'd like to ask some of you for your opinions on what the #1 most common hitting flaw is...
