Post-introducing Core wOBA
So on Twitter recently, and in the past, and really from the beginning 15 years ago, have stayed away from wOBA because it looks complex. Even introducing Standard wOBA hasn’t helped. So, here is Core wOBA:
- 2 x BB+HBP
- 3 x 1B
- 4 x 2B
- 5 x 3B
- 6 x HR
All divided by PA
(No exceptions for IBB, sac bunts, SF, reached on error.)
The above is also 2*(H+BB+HB) + TB if you prefer it that way.
How does this look for 2020? League average is luckily right around 1.000.
This allows you to also like it to wRC+ and wOBA if you are fans of those scales:
- If you wanted wRC+, it would be:
200*CoreWOBA - 100
Soto for example has a 1.526 CoreWOBA, which would comes in at 205, compared to his actual wRC+ of 201.
Adell has 0.674, which translates to 35 compared to his wRC+ of 29.
- If you wanted wOBA from CoreWOBA, multiply by 0.320.
Soto 1.526 times 0.320 comes in at 0.488, and his wOBA is .478.
Adell .674 translates to .216 compared to his wOBA of .212
