Sprint Speed is Statcast’s foot speed metric, defined as “feet per second
in a player’s fastest one-second window” on individual plays. For a player’
s seasonal average, the following two types of plays currently qualify for
inclusion in Sprint Speed. The best of these runs, approximately two-thirds,
are averaged for a player’s seasonal average.
* Runs of two bases or more on non-homers, excluding being a runner on second
base when an extra base hit happens
* Home to first on “topped” or “weakly hit” balls.
The Major League average on a "competitive" play is 27 ft/sec, and the
competitive range is roughly from 23 ft/sec (poor) to 30 ft/sec (elite). A
Bolt is any run above 30ft/sec. A player must have at least 10 competitive
runs to qualify for this leaderboard.
其实上面就有解释了
*非全垒打状态下，至少两个垒包（含）以上的跑垒，包括击出二垒安打的跑垒、原
本在二垒然后借由安打跑回本垒得分的跑垒等。
*打到球的上缘或击出软弱滚地球后，往一垒冲刺的跑垒。
跑垒极速算法就是符合上述两个条件当中筛出最快的三分之二来做平均
23 ft/sec (Poor)
30 ft/sec (elite)
above 30 ft/sec (Bolt)
