Lately my son (13) has had way more than his share of pop ups and fly outs. I've watched him swing in the cage and frankly I can't see much that he's doing wrong. He's in a good athletic position in his stance, his head stays still, his hip rotation looks good, etc. So... any thoughts on common hitting flaws that I am overlooking (and keep it simple please, I don't have a phD in swingology). I don't have a current video of him, but should be able to come up with one in a few days.
