Use a lighter bat. You won't be able to hit for as much power, but you'll get more hits in the long run.

the trick is to step just right. i play 14u travel ball and have a 10 something mph swing. when the pitcher or whoever throws u the ball you have to time when you put ur weight back and step so to hit accuretly and with more speed. also bringing the bat back and forward insanly when you start to rotate ur hips. a lighter bat will help but it doesnt really matter as long as you knw when to start rotating your hips and swing at the same time.
