In-Season Batter Regression Tool Updated
click to enlarge Earlier this year I released a tool that allows you to quickly calculate what a batter's offensive line might look like if they were sporting the same BABIP and HR/FB this year as their 3-year averages. The tool isn't a competitor to ZiPS or any other projection tool, rather it...
Mets wOBA By Position
Weighted on-base average ("wOBA") is the statistic I talk about at parties. Simultaneously useful and accessible, an advanced math degree is not required to understand and appreciate probably the best* publicly available offensive statistic. It correlates with run scoring better than batting...
Visualizing AL Central Hitters: wOBA through May 12th
Divisional wOBA and FIP Comparisons - April/May NLE - Hitters | NLE - Pitchers | ALE - Hitters | ALE - Pitchers | ALC - Hitters (Click to enlarge) Geez, I wonder why the Royals and Indians are fourth and fifth respectively in the AL in scoring? Oh, that's right, they each have six regular...
Oh What a Difference a Year Makes (or Not)
(Click to enlarge) I've been looking at first month batter performance data for another project and thought it would be interesting to see how players performed this April compared to last year. Keep in mind, there's basically no correlation between April performances (r=.075 for 2011 and...
Comparing the Mets' pitch count splits against MLB averages from 2002-2010
The Mets certainly give the impression of a good idea at the plate during their recent five-game winning streak. They're hitting, moving runners, and generally performing as well as one could ask in late April (except for the bunting, of course). It's too early to determine sustainability for much...
Back of the Envelope: Mets Shouldn't Bank on Hitter Regress to Improve the Offense
(Click to enlarge) When you ask Sandy Alderson, the Mets new GM, how he can expect the team to improve next year without making significant moves to alter the roster--particularly on offense--his reply has been that many starters are likely to rebound from a down 2010. Certainly his answer is...
Batter Regress Tool Updated with xBABIP and more Players
After some great comments and suggestions I've updated the Batter Regress Tool (original can be found here)--again, best viewed in wide format. The tool now incorporates xBABIP for 2010 and a player's 3-year average for 2007-2009. Additionally, the tool now includes all batters that had >=100...
Longoria, Rolen, and Wright: Player Volatility Part II
In my first column on player volatility I took a look at David Wright's in-season performance over time. The idea was to begin (and I stress begin) teasing out this idea of how an individual player's performance varies from game to game (or stretches of games). Originally I took the 10-game...
Custom wOBA and Linear Weights Through 2010: Baseball Databank Data Dump 2.1
A rare photo of Tom Tango, seen here calculating linear weights. You know what wOBA is, right? If not, get hip to it. In short, wOBA (weighted On-Base Average) was created by Tom Tango as a way of more accurately expressing a player's offensive value (according to the linear...
BtB Power Rankings: NL Offenses
Continuing our look at how teams rank based on the inputs into the power rankings, we continue tonight with National League offenses. Once again, here's a quick key for what you'll see presented below: wOBA = The Book's statistic, but park adjusted, and using data from both offense and...
