Last year I reintroduced VOL, a custom metric that attempts to measure the relative volatility of a hitter’s day to day performance. It is far from a perfect metric, but at the moment it’s what we have.
If you recall, a lower VOL value is better in the sense that it indicates a hitter has been more consistent offensively. However, both good and bad hitters can be consistent, so a lower VOL always needs to be viewed in the proper context. The other thing to keep in my mind is that (as a reader pointed out) there is a strong correlation between VOL and PA/G, as we can see by looking at VOL and batting order position (for 2013):

Tigers’ fans should be happy to see their team at number two on the list, as they have the second-highest team wOBA and do the second best job of replicating that performance on a game-to-game basis. Combine a consistently great offense with that rotation and it’s easy to see why Detroit should make another deep run this post-season.
The Braves offense turns out to be the most inconsistent — slightly better than average, but inconsistent. Now, given their pitching this may not be as big of an issue were they more of an average- to below-average run prevention team. However, it makes you wonder how they will perform in the different context of the postseason.
That’s all for now. Like the velocity loss leader boards, I will be updating VOL throughout the season, hopefully on a monthly basis.
