FanShot Case of the Mondays

Welcome back from your weekend! Here's a rundown of what has gone on down below in the FanShots section.

Over at FanGraphs, Dave Cameron reveals that Evan Longoria has been worth about as much as Albert Pujols's average seasons through his first 637 plate appearances, and calls him the best player in the American League. The question, of course, is whether or not that's enough of a sample size to call someone the best. The post itself incited quite the discussion over at FG, and there's some good talk as well in our own comments section about how much of it is actually luck.

The Star Ledger of New Jersey cited Leverage Index in a story. Correctly, even.

Kiley McDaniel heads over to Baseball Prospectus and puts together the first new entry to their "Basics" series in quite some time: an excellent article on the Latin baseball market. A great introduction on what goes on down there, and since it's part of Basics, it's free.

Bert Blyleven does not believe in "pitching to the score."

Matt Swartz gives us improved BABIP projections using batted ball types. I'm very interested in seeing a discussion on this because, frankly, I'm struggling to really grasp it on my own, and I'm not one to just be satisfied with good information unless I also understand it.

Moving one step closer to world domination, FanGraphs has added daily-updated in-season ZiPS projections to their player pages. I guess that's kinda cool. . .

Over at the Baseball Analysts, Dave Allen has put together graphs listing the run value of pitches by location and movement. Here's an example posted by Sky in the comments (red being high value, blue being lower):

In the article there are also nifty graphs showing the best, worst and most average pitches by pitcher. Great stuff going on.

TusconRoyal linked to a blog post looking at how inclusion in the Rule 4 draft has meant for Puerto Rican baseball, and what it would mean for the Domincan or Venezuela if they were included.

Sky Andercheck at TBA looked at the most improbable scoreless innings streaks in baseball history. The champion, unsurprisingly, is Orel Hershiser, just barely over Walter Johnson and a guy I'll bet many here have never heard of. Zack Greinke came around seven innings short of being the most improbable.

A reader of Tom Tango's supplied his data suggesting a new run estimator, and is looking for some peer review. I'm looking for someone smarter than I to put it in to layman's terms. So for those of you who really get the number crunching out there, you should head over and leave your thoughts on Tango's blog and explanations on ours.

Finally, quick, last second shots: some very, very early plans for San Jose to prepare for a potential A's move, Shyster Ball reviews Selena Roberts's book, and Sean Foreman discusses RetroSheet data through the 1920s and what it means for Baseball Reference (not much). 

There has been a lot more discussion going on in the FanShots lately, which is awesome. It's a great plate for discourse, so I encourage everyone to keep that up. It makes my day when I scroll by and see a lot of bold, blue numbers under the titles. Keep up the good work, everybody!

BABIP

Thanks for linking to my post about the BABIP article I wrote. I definitely look forward to a discussion on it. If you have any questions about it, or if anything’s not quite clear, please let me know.

In general, the point was that most projection systems just regress BABIP to the mean a lot, because they don’t break it down by GB/FB/LD, and simply knowing previous years’ BABIP without context does not tell you much. But you can approximate it much better with knowing BABIP for each batted ball type and breaking down a few extra stats (infield flies, infield hits, overall power numbers, etc.).

With three years of 300 PA, you can get an estimate that has a .57 correlation with BABIP; PECOTA and CHONE’s BABIP estimates both have .44 correlations with true BABIP only, and ZIPS, OLIVER, and MARCEL do slightly worse.

btw

forgot to mention— last name is Swartz, not Schwartz actually. I get that a lot :)

I actually got that and it makes sense to me.

I just need to get the nitty gritty of it, either through following discussion or staring at it long enough.
