Expected wOBA Leaderboards: Almost All July
A Brief Explanation of What This Is
In the not very distant past, I presented something in the Notes called “Expected wOBA,” itself essentially a version of Bradley Woodrum’s Fielding Independent wOBA but with regressed (as opposed to raw) home-run, walk, and strikeout rates — and a (somewhat haphazardly) regressed version of Woodrum’s updated xBABIP formula, as well — as the inputs.

The idea behind Expected wOBA is to estimate something like a player’s true talent over the course of X plate appearances, where X equals a relatively low number.

Expected wOBA Leaders: Almost All July
Here are the leaders in Expected wOBA (xWOBA, in this case) among all batters over almost all July — which is to say, all of July except for July 31st, on account of that’s when I ran the data. Note that anything beginning with an -x- has been regressed. Note also that, in the absence of actual research having been done on it, I’ve opted to regress stolen-base percentage to 100 plate appearances (as, unregressed, it gives undue credit to players who’ve stolen one base in, for example, just four plate appearances).

Here’s the leaderboard, made just long enough to include Ryan Ludwick:

Name Team PA xHR% xBB% xK% xSB% xXBABIP xWOBA
Edwin Encarnacion Blue Jays 98 3.8% 14.1% 14.1% 1.0% .337 .403

Today’s Notable Games
Arizona at Los Angeles NL | 15:10 ET ***MLB.TV Free Game***
Shane Victorino (431 PA, 101 wRC+, .278 BABIP, 2.1 WAR) makes his debut as a Dodger, probably.

Readers’ Preferred Broadcast: Los Angeles NL.

Miami at Atlanta | 19:10 ET
Not only is the legitimately effective Ben Sheets (18.0 IP, 93 xFIP-, 0.6 WAR) pitching, but so is left-hander Wade LeBlanc, who makes his first start of the season. LeBlanc’s line out of the bullpen (15.2 IP, 113 xFIP-, 0.2 WAR) hasn’t set a world, let alone the world, on fire, but his strikeout-to-walk numbers have generally been above average at every level.

Readers’ Preferred Broadcast: Atlanta Radio.

I noticed that the difference in wOBA and xWOBA is greater for potential fallers than potential risers, and I seem to recall noticing this before. am I just selectively remembering, or do we usually see this? If we do, could that mean it’s easier to be “lucky” than “unlucky” in wOBA compared to xWOBA?

If that is true, it really isn’t luck. Luck should simply be a random error normally distributed around a mean of 0. One possible explanation (if true) is that the players that are “unlucky” are not getting enough playing time to be equally as unlucky as players that are lucky.

The real problem is that BABIP fluctuation is not simply affected by luck or factors outside of the player’s control. Players can change their swing/get lazy and hit more or less LDs then they used to. This would likely raise/lower their BABIP respectively. So then, it isn’t reasonable to always expect BABIP to regress to something such as a career BABIP simply because the luck error factor is expected to be 0.
