Define wins above replacement (WAR) and give one short worked example.

# Wins Above Replacement (WAR) **WAR** is a baseball statistic that estimates the total number of wins a player contributes to their team compared to a "replacement-level" player (a readily available minor league call-up). WAR combines all aspects of a player's contribution: - Batting - Baserunning - Fielding - Position difficulty - Pitching (for pitchers) The scale is roughly: 0-1 = replacement, 2 = average starter, 5 = All-Star, 8+ = MVP candidate. ## Simple Worked Example **Mike Trout in 2012:** 1. **Batting runs above average:** +48 runs 2. **Baserunning runs above average:** +8 runs 3. **Fielding runs above average:** +6 runs 4. **Positional adjustment (CF):** +3 runs 5. **Replacement level adjustment:** +20 runs (based on playing time) **Total runs above replacement:** 48 + 8 + 6 + 3 + 20 = **85 runs** **Convert to wins:** 85 runs ÷ 10 runs/win = **8.5 WAR** This means Trout was worth about 8.5 more wins than a replacement-level player would have been in his place—making him an MVP-caliber player that season.
