ALPost89: SWING EXTENDER INVENTION

Documents describing the "Swing Extender" baseball bat training tool, invented by Jim Derochea of Stoughton, MA (jimderochea@comcast.net) The concept is to give a player a feedback tool, used off a tee or during soft toss, to ensure that they are keeping the bat head through the zone and beyond past the contact point, rather than "cutting" the swing off at contact.
