wOBA by David Appelman November 25, 2008 The statistic wOBA (weight on base average) is now available in the player pages, leaderboards, team pages, my team pages, and the projections. wOBA, created by Tom Tango, is a version of linear weights that has been weighted to fit an OBP scale. The weights have been properly adjusted by season and for the minor leagues by season and by league.
