Cabbagedad, any hitting coach teaching “loft” ie launch angle necessary to produce HRs to a pre-high school player needs to have their heads examined. That approach requires a physically mature player with an already fundamentally sound swing. Loft approach it situational, depending on the pitch and it’s plane on approach to the plate. Having a loft launch angle on a a high fastball is going to result in a lot of pop flies and strike outs. Even when the pitch is the right one for that approach, many HS aged players are simply not strong enough to generate anything more than a fly-ball for an out.
