See guys hit fly balls and deep shots in bp. But in games, they rarely hit fly balls, mostly line drives - however they obviously have power, but don't hit the moon shots you see in bp.
Or guys who work on hitting liners to all fields in bp, but in games roll over the top or hit fly balls.
I've often wondered if typical bp is a good practice. Coach throwing a slower pitch from 50 feet or so is not the same as a pitcher from the mound.
Is there a better way?
