New Pitcher Value Stats
The Value (WAR) section for pitchers has been updated to help further break out a pitcher’s value. These stats are now available in the leaderboards and player pages.
We’ve added the following stats:
RA9-Wins – Wins above replacement calculated with RA9. This is both park adjusted and league adjusted.
BIP-Wins – Wins above average based on BABIP. This is both park and league adjusted.
LOB-Wins – Sequencing (and miscellaneous) wins above average calculated as RA9Wins – WAR – BIPWins.
FDP-Wins (Fielder Dependent Wins) – This is the full difference between RA9Wins and WAR, or BIPWins + LOBWins.
WAR – Wins Above Replacement remains unchanged.
Dave Cameron will have two posts with more details about these new stats at 9:00am and 10:00am and will be answering questions during his 12:00pm chat.
The full formula for BIP-Wins is:
((((H-HR)*(w1B * p1B + w2B * pxBH) ) / (TBF – HR – BB – HBP – SO)) – lgwBABIP) * (TBF – HR – BB – HBP – SO) / PF / RtW * -1
p1B = singles as a percentage of hits that are not home runs
pxBH = doubles and triples as a percentage of hits that are not home runs
w1B = linear weight value of a single
w2B = linear weight value of a double
RtW = runs to wins converter
PF = park factor
lgwBABIP = league average: ((H-HR)*(w1B * p1B + w2B * pxBH)) / (TBF – HR – BB – HBP – SO)
