As of May 2015, the best Little League bat is the Demarini CF7 Youth, as noted by Baseball-Stuff.com. Bat selection often depends on individual preference, so while this may be a top-rated bat, it may not suit all hitters.
The Demarini CF7 youth baseball bat is one of the most purchased bats among youth baseball players. Constructed of carbon-fiber composite material using a two-piece design, it's one of the lightest bats on the market and features flexing capability when it contacts the ball, producing a trampoline effect. Furthermore, it is designed to offer a larger sweet spot, which provides added power.
