Worth claims that whiplash produced by this bat has been reduced by 30% compared to previous models, citing the thinner taper along the bat’s midsection. The EST’s barrel has been designed to be flexible, along with a stiff handle. This feature provides maximum ball speed with minimal discomfort to the player. This bat also features a “Pro Pebble” grip, a thin and textured material aimed at providing as much control as possible. The Worth EST is available in several different length/weight configurations, and is approved by the ASA, USSSA, NSA and ISF.
