The bat that was built for maximum power, speed and balance is back and better than ever with a larger sweet spot and unmatched feel for when you step into the box. Louisville Slugger 2017 Prime 917 features Patented TRU3 technology, which allows for independent movement between the barrel and the handle which controls vibration and provides unmatched feel on contact. By controlling vibration, you are able to maintain acceleration through the impact with less worry of major hand sting. With the one-piece construction, Louisville Slugger Prime 917 has a lighter wing weight so you can maximize control and get the ultimate performance from your Baseball bat.
