Power-Speed Score FAQ
What is the power-speed score?
It is a statistic that combines a player’s home run and stolen base totals into one number using the harmonic mean formula 2 * HR * SB / (HR + SB).
Why use the harmonic mean?
The harmonic mean punishes imbalance, rewarding players who excel in both power and speed rather than just one category.
Who invented the metric?
Bill James, the noted baseball analyst, created the power-speed number in the 1980s as part of his sabermetric research.
What is a good season score?
A score above 20 is considered strong.
Reaching 30 or more is rare and signals elite two-way production.
Does the stat work for career totals?
Yes, you can sum a player’s lifetime home runs and steals, then apply the same formula to get a career power-speed score.
