Statcast now tracks every player’s speed using a new metric called “sprint speed.” They define it as “feet per second in a player’s fastest one-second window.” MLB baserunners average 27 feet per second and the fastest runners typically cover 30 feet per second, with the slowest dragging behind around 23 feet per second.
Based on the metrics, the Cubs’ fastest baserunner is…Ian Happ. Though he runs with his arms waving side-to-side, the aggressive rookie covers 29 feet per second, faster by a full second than the next fastest Cub, Kris Bryant. See how the rest rate below.
Also surprising to me was Albert Almora Jr.
