How the bat is made is what differentiates it from the typical regulation bat used by major league players. In addition to being lighter and thinner, the bat is also much longer compared to the normal bat. It ranges between 35 – 37 inches in terms of length. In terms of weight, the bat weighs between 17 – 22 ounces. Of great importance to note is the fact that the bat features a bigger barrel than the normal ones. Since it’s flatter and features a small diameter, it’s ideal when it comes to hitting ground balls as well as pop flies. This would be necessary during the fielding practice of any team regardless of the level.
Within league standards there is ample latitude for individual variation, many batters settling on their own bat profile, or one used by a successful batter. Formerly, bats were hand-turned from a template with precise calibration points; today they are machine-turned to a fixed metal template. Historically significant templates may be kept in a bat manufacturers' vault; for example, Babe Ruth's template, which became popular among major-league players, is R43 in the Louisville Slugger archives.
“They’re not moving, their feet are apart, their gloves are on the ground, backs are flat, and they’re working down to up, out to in, basically a steady roll back and forth probably 15 to 20 each,” Bates said. “Then they’ll turn their body, work glove side for another 15 to 20, and backhand 15 to 20. No movement, really, just making sure we’re watching the ball roll into our glove, fielding it, and doing all the things fundamentally correct.”
