1. What Is WAR?

WAR (Wins Above Replacement) is a comprehensive baseball statistic that attempts to measure a player's total value to their team by estimating how many more wins they're worth than a replacement-level player.

2. How Does WAR Work?

The calculator uses the basic WAR equation:

Where each component is measured in runs:

• Batting - Offensive production at the plate
• Base Running - Value added on the bases
• Fielding - Defensive value in the field
• Positional - Adjustment for position difficulty
• Replacement - Runs a replacement player would provide

Explanation: The components are converted from runs to wins (typically about 10 runs = 1 win).

3. Importance of WAR

Details: WAR provides a single number that accounts for all aspects of a player's performance, making it valuable for comparing players across positions and eras.

4. Using the Calculator

Tips: Enter each component in runs. For reference, an average MLB player is worth about 2 WAR per season, while MVP candidates often exceed 6 WAR.

5. Frequently Asked Questions (FAQ)

Q1: Why use WAR instead of traditional stats?
A: WAR accounts for all aspects of player contribution (offense, defense, position) in a single metric.

Q2: What is a replacement-level player?
A: A readily available minor league player or bench player who would cost nothing to acquire.

Q3: Are there different WAR calculations?
A: Yes, Fangraphs (fWAR) and Baseball-Reference (bWAR) calculate it slightly differently.

Q4: What's a good WAR value?
A: 0-1 WAR = replacement level; 2-3 = solid starter; 4-5 = All-Star; 6+ = MVP candidate.

Q5: Can WAR be negative?
A: Yes, negative WAR means a player performed worse than a replacement-level player.
