wOBA & Base Running Changes

To better isolate batting and base running skills, SB and CS have been removed from wOBA and given their own category wSB.

What’s Changed?

wOBA, wRAA, wRC, wRC+ – These all no longer include SB and CS. SB and CS have been removed entirely from the wOBA calculation include the weights calculation.

Batting – Batting in the Value section no longer includes SB and CS.

Base Running – Base Running in the Value section now includes SB and CS.

FanGraphs Guts! – Our Guts! section now has updated weights and the SB and CS weights for use in wOBA have been replaced with the raw run values.

What’s New?

wSB – how many runs above or below average a player is at stealing bases.

UBR – (miscellaneous baserunning / advancement) is now broken out into a separate category which is in the Advanced section. This contains all the information that was formerly just in Base Running.
