When Chicago Cubs reliever Scott Effross first learned his sidearm delivery, he watched a lot of hitting videos. Because he uses more lower-half load than a conventional pitching delivery, his process more closely resembles a hitter’s. Dissecting those hitting videos became a valuable tool, helping him tap into his lower half more while using his hips and core to get down the mound and keep his arm path consistent. “I’d see how guys would stay on their back legs and drive through,” Effross told the Tribune.
