  • Our Goal

    4 for 4 Player Acceleration is the area’s leading baseball instructional center. Our instructors are teaching what REALLY happens in a powerful swing. We’re not teaching the same old tired material and using drills left over from the 80’s. “Squish the bug” and “throw the hands” are terms you just won’t hear at 4 for 4. We teach you how to hit with your whole body and use state-of-the-art technology to help you learn faster. We use this technology to gather metrics (information) about your swing and the quality of contact you get with your swing. Having the tools to gather your metrics allows us to best know how to go about improving your swing.
