WAR = (Runs Created - Runs Allowed) / Innings Pitched
Glossary of Variables
- Runs Created: Estimated number of runs a player contributes to the team.
- Runs Allowed: Number of runs a player is responsible for allowing.
- Innings Pitched: Total innings a pitcher has pitched.
- WAR: Wins Above Replacement, a measure of a player's overall contribution to the team.
How It Works: A Step-by-Step Example
Consider a player with 50 Runs Created, 30 Runs Allowed, and 200 Innings Pitched. Using the formula, their WAR would be calculated as:
WAR = (50 - 30) / 200 = 0.10
