Looking for some ideas. Son has developed into a solid and consistent wood bat hitter. Sprays line drives to all fields and hits with power to the gaps. But when he picks up a metal bat, nearly 50% of what he hits end up as pop-ups to right field (he's a lefty). The bats are the same weight and drop. He almost never hits pop ups with wood.
Any thoughts on what might be going on here?
Thanks
HC
