UBR and wGDP are statistics developed by Mitchell Lichtman and provided to FanGraphs.

Base Running Runsīase Running Runs (BsR) at FanGraphs is the combination of Ultimate Base Running (UBR) for non-stolen base type base running, Weighted Stolen Base Runs (wSB) for stolen base and cost stealing value, and Weighted Grounded into Double Play Runs (wGDP) for runs added or subtract due to a hitters knack for avoiding or hitting into double plays. 0.95 for 95):īatting Runs = wRAA + (lgR/PA – (PF*lgR/PA))*PA + (lgR/PA – (AL or NL non-pitcher wRC/PA))*PAĮssentially, you are talking wRAA and adding or subtracting in runs based on their home park and their league. To adjust wRAA for park and league, you do the following with the park factor expressed as a decimal (i.e. WRAA is simply a non-adjusted Batting Runs.

To calculate their wRAA, do the following: The first step is to find Weighted Runs Above Average (wRAA) from the player’s wOBA, or you may simply find their wRAA on FanGraphs. Park Factors can be found here and wRC and PA for the leagues can be found using the leaderboards. League wOBA, wOBA Scale, and R/PA can be found here. You need the player’s wOBA, PA, and home park factor and you need League Average wOBA (lgwOBA), the wOBA Scale, MLB R/PA (lgR/PA), and the specific league (AL or NL) wRC and PA for non-pitchers. To calculate Batting Runs Above Average you only need to know three things about a player and several things about the league in general. Also, on the site we have a statistic called Off which is Batting + Base Running and Def which is Fielding + Positional Adjustment. It would be unwieldy to included everything about how we calculate the precise value of taking an extra base in this post, for example, but the links will fill in the gaps.

RAR and WAR communicate the same thing on different scales.īelow you will find a section on each of these components as well as links to entries that relate to those parts of the calculation. That provides use with Runs Above Replacement (RAR), which we convert to WAR by dividing it by Runs Per Win. We will consider each aspect of the equation in turn, but the basic structure is that we take Batting, Base Running, and Fielding runs above average, add in a positional adjustment, a league adjustment, and then add in runs so that we are comparing to replacement level instead of average. WAR = (Batting Runs + Base Running Runs + Fielding Runs + Positional Adjustment + League Adjustment +Replacement Runs) / (Runs Per Win) WAR combines a number of inputs, but all of which are available on the site. It’s simpler, both conceptually and mathematically, and it’s relatively straightforward to calculate. Below is the method for calculating WAR for position players.Ĭompared to WAR for pitchers, calculating position player WAR is a walk in the park.

If you would like to learn about WAR for pitchers, you can find the necessary details over at this Library page and if you want to know about WAR in general and how to use it, check out this page. Below is a breakdown of exactly how we calculate WAR for position players.

Wins Above Replacement (WAR), FanGraphs’ hallmark statistic, attempts to estimate a player’s total value relative to a free available player, such as a minor league free agent.
