MLB Advanced Analytics: wOBA-xwOBA Update
Mike Alexander breaks down wOBA vs. xwOBA for hitters and how it can be used as a tool to predict regression to the mean.
On tap this week for MLB Advanced Analytics is an update to wOBA-xwOBA. Weighted On-base Average is a stat that places weights At-Bat results progressively. It’s a better indicator of a player's skills than OBP or AVG. We enhance that even further by examining wOBA compared to xwOBA. It removes the luck of where a ball was hit and accounts for how well it was hit, rather. Statcast makes it easy by selecting the desired fields to get wOBA-xwOBA.
Here are the top fifteen in ascending order.
The top fifteen features many big bats. Smoak, both J. Martinez’s, and Ozuna are particularly interesting. Their already high wOBA could be even higher.
Guys like Alonso, Aguilar, and Schwaber have an approach with the goal of putting the ball in the air. That can result in less “luck.”
Danny Jansen has been slowly rebounding. Hopefully, he continues to get a handle on catching a major league staff and the results at the plate improve.
Khris Davis isn’t...
