The best ability is availability, players that cannot get on base are expendable. Athletes will gain an understanding of defenses and how best to beat them. Batters with an understanding of fielders weaknesses will be able to expose weak arms to get on base. When to bunt, which pitchers cannot throw accurately to bases w/ runners on will result in extra runs & forced errors.
Speed coaches from the NBA, USTF (United States Track & Field) and other NCAA programs will design drills to increase an athlete’s ability to transition from batters to baserunners. Specifically focusing on turning at 90 degrees and creating burst & separation.
