Weighted On-Base Average = wOBA
- Not all hits are created equal and the wOBA tries to reflect that. The weights given to each hit reflects their run value.
- If you can only choose one statistic to evaluate a hitter, this is a good place to start. It accurately reflects what is done at the plate.
- It is superior to OPS (On-Base + Slugging) due to an error of proportion
- Slugging is typically 1.8 times higher than on-base percentage. Therefore simply combining them overvalues slugging.
