WAR Overview

What WAR Measures

rs=w-458,h-229,cg-true,m

  • Considers all aspects of a players game and summarizes their total contributions in a single stat
    • Through a series of equations, overall effort is translated into wins (pitchers and pos. players use different methods / equations to arrive at a WAR number).
      • Specific calcluations for both ‘position players’ and ‘pitchers’ are found below.
  • WAR Allows us to figure out how much better someone is than a replacement level player (i.e. a guy you could acquire any time for the league minimum)
    • The League Minimum is $555,000 in 2019, up from $545,000 in 2018.

Generally Speaking

  • An accurate estimate of a players value to that point in the season
  • Top Brewer Career WARs:
    • R. Yount (77.3)
    • P.Molitor (60.0)
    • R. Braun (46.4)
    • C. Cooper (30.7)
    • D. Money (28.4)
  • Best Brewer Season WARs: 
    • R. Yount – 10.5 (1982)
    • C. Gomez – 7.8 (2013)
    • R. Braun – 7.7 (2011)
    • C. Yelich – 7.6 (2018)
    • T. Harper (1970)

WAR Is Relative…

rs=w-458,h-229,cg-true,m-2

  • Two Adjustments are applied to WAR:

    1. Positional: The TABLE shows us the adjustment applied
      • NOTE: If all positions produce at the same level, the catcher will have the highest WAR
    2. League: a small correction that allows each league’s runs above average balance to zero
  • TAKEAWAY: WAR is relative to effort, league and position for that year (a true ‘comparison stat’)

Collective WAR = Actual Wins

rs=w-458,h-229,cg-true

  • Adding all the WARs on a roster roughly adds up to equal the team’s actual win total.
  • A team made entirely of replacement level players will win 48 games per year (0.294 Winning Percentage)
  • A negative WAR means that when you consider everything a player does, he is worse than the league average

THE CALCULATION

WAR (Position Players)

BREW MATHsummary

Using the chart above, let’s list what concretely contributes to calculating WAR:

  • Weighted Runs Above Average (wRAA)
    • This is calculated using Weighted On-BAse Average (wOBA)
  • Ultimate Base Running (UBR) + Weighted Stolen Bases (wSB)
  • GIDP Avoidance Rate (Rdp)
  • Ultimate Zone Rating (UZR)
  • Replacement Level Multiplier
  • Adjustments (Position + League)

*** WAR is truly attempting to find a player’s OVERALL VALUE ***

WAR (Pitchers)

rs=h-650,cg-true-1

BREW MATHsummary

Pitcher WAR is calculated differently depending on who you ask:

  • Baseball-Reference
    • WAR = WAR_rep + WAA + WAA_adj
    • Driven by Runs Allowed and Innings Pitched
  • FanGraphs
    • WAR = [(League “FIP” – “FIP”) / Pitcher Specific Runs Per Win] + Replacement Level) * (IP/9)] * Leverage Multiplier for Relievers] + League Correction
      • Driven by FIP = (13*HR)+(3*(BB+HBP-IBB))-(2*K))/IP + lg_specific_constant
      • FIP Constant is usually around 3.20 and changes every year

MUCH ADO ABOUT SOMETHING:

To Date, Wins Above Replacement (WAR) is the Best Single Metric We Have to Analyze a Player’s Overall Value. When you look at who tops the leader boards, it is a who’s who of elite talent…
