This device mechanically compresses the composite material of a softball bat’s barrel. This compression alters the bat’s structure, potentially increasing its trampoline effect upon contact with a softball. A typical process involves rotating the bat against rollers under controlled pressure.
The purported advantages of this process include improved bat performance and enhanced “sweet spot.” Historically, altering bat composition has been a point of contention within the sport, leading to regulations and standards aimed at ensuring fair play and player safety. Understanding the effects of mechanical alteration on bat performance is crucial for both players and governing bodies.
