Like so many others, Oneil Cruz uses the ProHitter hitting aid to help him avoid choking the bat handle, which increases overall bat speed. It also does a great job of protecting the thumb from injury caused by jam-shots on inside pitches. It may be a small piece of plastic, but it is one of the most popular products in the MLB.
Get the ProHitter at DicksSportingGoods.com for $12-$14.
