I’ve begun to add wOBA (Weighted On Base Average) and Lefty/Righty splits to the site. Currently, they are only available on the player’s page in the Batting Graph. L/R splits are available from 1952 until the current season.
I should mention that my wOBA calculations DO NOT include SB/CS data. This was done on purpose to be able to compare L/R to the overall value. The BaseRuns / 27 Outs DOES include SB/CS data. For the most part, the wOBA and R/27 percentile should be very similar, except for the top base stealers (see Carl Crawford). Also, just like all the other stats, the wOBA percentile ranking IS park adjusted.
There are 3 bars in the wOBA section. The bar on the left is vs LHP. The middle bar is overall (vs All). The bar on the right is vs RHP. You’ll notice that there is a lot of volatility from year to year for some players. Take Matt Wieters for example….
Wieters vs LHP is in the 100th percentile in 2011, while he was in the 1st percentile in 2010. As a switch hitter, it will be interesting to see if this trend continues in the future.
Finally, you’ve probably noticed that I’ve added the ability to look at individual seasons on the Batting Graph. I’ve added the number of Plate Appearances for each season to show the sample size.
Next, I plan on adding the same L/R wOBA to the pitcher’s graph.
Everything looks great, Dan.
By the way, did you notice that it’s Matt Kemp’s birthday today, but he just barely missed the top five for today – only by .3 WAR (that’s what I have the site set on right now, anyway). I was just thinking that, if he has another game like he did yesterday (4/5, 3 2B, 1 HR) as a birthday present to himself, he just might make it onto the list. That would be pretty cool! Anyway, thanks for the new additions. And crazy about Wieters. Never knew.
Excuse me, I meant .3 WS above. Oops.
He’ll definitely be the top 5 by the end of the season. Speaking of Kemp, he’s only .004 Batting Average pts and 1 HR away from winning the triple crown. Amazing
Now he’s tied for the HR lead! And he’s trailing in the batting race by only .003. First of all, congrats to him, especially to be able to put together a season like that playing at Dodger Stadium. But, as a Brewers fan, it’s a bit of a tough pill to swallow that he passed Braun in runs and Fielder in RBI, and that he’s gunning for Braun in the batting race – not to mention the MVP chase! After last night’s game, it’s going to be hard for me (as a native Milwaukeean) NOT to vote for Braun when the Internet Baseball Awards voting comes around, but I understand why anyone else would vote for Kemp. Amazing season, all around.
Just a quick update….
I’ve added the same wOBA style bars to the Pitching Graphs and also added the ability to view specific seasons as well as a career graph.
Just a quick note about Pitcher’s wOBA. They are park adjusted, but NOT adjusted for defense.
A couple of questions:
Are there any plans to add wOBA and wOBA splits to the career data downloads?
If so, will these data be available park adjusted?
today, I soewhd the projected platoon splits for the Marlins for the 2011 season. The cool thing about projecting not only overall performance
