Answer Capsule

WAR = (Batting + Base Running + Fielding + Positional Adj) / Runs Per Win. ~$8M per WAR in free agency. 60+ career WAR = Hall of Fame threshold. 2 WAR = starter, 5+ = All-Star, 8+ = MVP.

Key Takeaways

  • WAR sums offensive, base running, fielding runs, and positional adjustment.
  • Divide by runs per win (~10) to convert to wins above replacement.
  • bWAR (Baseball Reference) and fWAR (FanGraphs) use different methods.

Did You Know?

👑Babe Ruth holds the career WAR record at 183.1 bWAR.
Mike Trout had 10+ WAR seasons multiple times in his prime.
📊2 WAR = solid starter; 5+ = All-Star; 8+ = MVP caliber.
Positional adjustment is negative for 1B/DH, positive for SS/C.
📈Runs per win varies by league and era; ~10 is typical.

How It Works

WAR = (Off + BR + Field + PosAdj) / RPW

WAR sums offensive runs above average, base running runs, fielding runs, and positional adjustment. Divide by runs per win (~10) to convert to wins. Replacement level is defined as ~0.3 WAR per 600 PA.
