Pitcher WAR
(fWAR + rWAR) / 2
This methodology gives an equal split to actual performance and actual results.
fWAR
Uses FIP to figure out the amount of runs above replacement a pitcher saved and then converts that total into wins.
Park adjusted.
Taken from FanGraphs.
rWAR
Uses ERA to figure out the amount of runs above replacement a pitcher saved and then coverts that total into wins.
Park adjusted.
Taken from Baseball Reference.
Batter WAR
Infielders & Outfielders
[wRAA + ((UBR + (EQBRR - EQSBR)) / 2) + ((DRS + FRAA) / 2) + POS + REP] / 10
(oWAR + bWAR + dWAR + POS + REP) / 10
Catchers
[wRAA + ((UBR + (EQBRR - EQSBR)) / 2) + (DRS ARM + Framing + Blocking) + POS + REP] / 10
(oWAR + bWAR + dWAR + POS + REP) / 10
oWAR
Uses wRAA to determine the amount of runs above average that a player was worth offensively.
Park adjusted.
Taken from FanGraphs.
bWAR
Averages UBR and EQBRR to determine the amount of runs above average that a player was worth on the basepaths. EQSBR is subtracted from EQBRR so that both UBR and EQBRR are without influence from stolen bases, which are already factored into the equation through oWAR.
Park adjusted.
UBR taken from FanGraphs. EQBRR taken from Baseball Prospectus.
dWAR
Infielders & Outfielders
Averages DRS and FRAA to determine the amount of runs above average a player was worth defensively. I choose these two metrics because I think they evaluate defense the best.
Park adjusted.
DRS taken from FanGraphs. FRAA taken from Baseball Prospectus.
Catchers
Sums the amount of runs above average a catcher was worth defensively through DRS ARM (throwing ability), Framing (framing ability), and Blocking (blocking ability).
Park adjusted.
DRS ARM taken from FanGraphs. Framing taken from Baseball Prospectus. Blocking taken from The Hardball Times.
POS
Positional adjustment based on playing time expressed in runs.
Taken from FanGraphs.
REP
Replacement level adjustment based on playing time expressed in runs.
Taken from FanGraphs.
Prospects are ranked on a mix of Ceiling and Risk.
Personally, I tend to favor Ceiling over Risk because you’d rather find one regular starter than five utility infielders.
Ceiling
Represents the ceiling of the player’s current skills and any projection the player has. Will not take that projection beyond reason.
Position Player Example: A position player will not project to grow six inches and add 50 pounds of muscle.
Pitcher Example: A pitcher will not project to add three pitches and 15 miles per hour.
Tier 1: Elite position players. #1 starting pitchers.
Tier 2: Good position players. #1/#2 and #2 starting pitchers.
Tier 3: Average position players. #2/#3 and #3 starting pitchers. Closer relief pitchers.
Tier 4: Mediocre position players. #3/#4 and #4 starting pitchers. Late relief pitchers.
Tier 5: Reserve position players. #4/#5 & #5 starting pitchers. Middle relief pitchers.
Tier 6: Depth position players. Depth starting pitchers. Early and Situational relief pitchers.
Tier 7: Minor position players. Minor starting pitchers. Minor relief pitchers.
Risk
Represents the amount of risk a player has.
Tier 1: Very High.
Tier 2: High.
Tier 3: Average.
Tier 4: Low.
Tier 5: Very Low.
