1. What is Defensive WAR?

Defensive WAR (Wins Above Replacement) measures a player's defensive value in terms of how many more wins they're worth than a replacement-level player at their position. It combines defensive runs saved with positional adjustments.

2. How Does the Calculator Work?

The calculator uses the Defensive WAR equation:

Where:

• Defensive Runs Above Average — Total defensive runs saved compared to average
• Runs Per Win — Typically around 9-10 runs per win in modern baseball
• Positional Adjustment — Varies by position (e.g., +7.5 for SS, -7.5 for 1B)

Explanation: The equation converts defensive runs to wins and accounts for the difficulty of each defensive position.

3. Importance of Defensive WAR

Details: Defensive WAR helps evaluate players' complete value by quantifying their defensive contributions, which are often overlooked in traditional stats.

4. Using the Calculator

Tips: Enter defensive runs above average (from advanced metrics), runs per win (typically 9-10), and the positional adjustment for the player's position.

5. Frequently Asked Questions (FAQ)

Q1: What's a good Defensive WAR?
A: 0 is average. +2 is excellent, +5 is Gold Glove caliber. Negative values indicate below-average defense.

Q2: Where do I find defensive runs above average?
A: Available from advanced metrics like UZR (Ultimate Zone Rating) or DRS (Defensive Runs Saved).

Q3: What are typical positional adjustments?
A: Catcher: +12.5, SS: +7.5, 2B: +2.5, 3B: +2.5, CF: +2.5, LF/RF: -7.5, 1B: -12.5, DH: -17.5.

Q4: Why does runs per win vary?
A: It depends on run environment - higher scoring leagues have higher runs per win values (typically 9-10 in MLB).

Q5: Can defensive WAR be negative?
A: Yes, indicating the player's defense costs their team wins compared to a replacement player.
