Make every swing count with this 2019 Louisville Slugger Prime 919 baseball bat. Engineered with Louisville Slugger's proprietary MicroForm barrel design, this bat fuses together layers of 100% composite material to provide a lighter swing weight and maximize pop. Feel more in control every time you step to the plate thanks to innovative VCX technology, which allows for independent movement between the barrel and handle so there's virtually no sting in the hands when you swing through the ball. As an added bonus, this baseball bat's specialized RTX end cap design ensures the weight is evenly distributed for improved balance, while also maximizing barrel shape for a more generous sweet spot.
