As I did during the season, I’ll update each day’s play two or three days later. For instance, I just updated all stats through October 7th. Starting in a few days, I’ll also start compiling stats for the Arizona Fall League: watch this space for updates on that score.

As many of you have pointed out to me, there are errors in the data.  I’m aware of most of them, and working to correct them.  The biggest flaw is that, especially in April and August, non-pitchers are being credited with innings pitched.  Accordingly, many pitchers haven’t been credited with all of their IP.  The other major problem is out-counting–it probably only occurs once every several games, but occasionally I have events occuring with 3 outs already recorded.

Now that I no longer need to spend time each day updating the databases, I can focus on expanding the site’s coverage.  I’m eventually going to branch out into a variety of defensive stats, add all the 2005 splits I can find sources for, and perhaps include pitch-by-pitch data.  I’m also going to see what I can accomplish with all of this data and create a research section on the site for myself and others to post their findings.

I also made several corrections to my method for calculating MLEs for pitchers, to bring my numbers into closer agreement with Sean Smith’s.  (I am using his method–I might as well do it right!)  Further, I now alter batted ball numbers for Park and MLE stats.  Since K’s, BB’s, and HR’s often differ from a player’s overall stat line, the number of batted balls changes–I just adjust the batted-ball totals to reflect that.

Other exciting new features are on their way!

Also, you may have noticed that when players have no at-bats, their rate stats (AVG, OBP, etc.) are given as “0″ instead of “.000.”  That’s by design, but due to a mistake in my code, hitters with no at-bats but at least one plate appearance weren’t showing OBPs or OPSs.  That’s fixed.  Now all OBPs and OPSs should be correct–or at least consistent with the rest of my data.

It’s simple, it’s fun, and it saves you an excel query!

Now, you can see aggregate batted ball data for both pitchers and hitters for each team and league in Minor League Baseball.  For example, see team pitching data for the Altoona Curve, or total batted ball data for the Midwest League.  For some reason, total batting and pitching data doesn’t match up exactly–in the case of the MWL, it’s off by about two hundreths of a percent.  This happened when I first aggregated league splits, as well; I’ll eventually figure out what’s amiss and fix it up.

Also, I just fixed the script to generate a player’s cumulative stats (see Ryan Braun’s, here).  The way my data is stored, if a player has accumulated any stats for a certain split (say, batting as a leftfielder, or pitching in the third inning), there’s still a blank line.  All along, the regular team-specific splits table scripts edited out those blank lines before showing them to you.  I forgot to include that in the cumulative stat script.  It’s now fixed, so you’ll have far fewer useless zeroes to distract you next time you look at a player’s overall numbers.

Enjoy!

Today’s incremental improvement: the league averages are now available in team splits tables, anad the batted ball percentages are available in both team and league splits tables.  Now it’s as easy as moving your mouse to find out what percent of fly balls turn into HRs in the Texas League, or to compare Brevard County Manatees pitchers’ K rates to the FSL average.

And yes, I know how much you’ve always wanted to do that.

In other words, it should look something like this:

(For some reason, when I took a screenshot, the cursor disappeared: in that example, the cursor is hovering over the “9″ in the “L” column.)

The league averages have been part of the splits tables for a few weeks now; just this morning I added several new tools for batted ball analysis. Mouse over the groundball total, and you’ll see the player’s groundball percentage. Line drive total: line drive percentage. Fly ball total: home runs per fly ball. Popup total: infield flies per fly ball [P/(F+P)].

I haven’t yet included any of those acronyms on team or league pages, but that’s on the list.

If you can’t see the dotted black lines, and nothing happens when you mouse over those numbers, you should switch to Firefox. Actually, you should switch to Firefox anyway. I don’t completely understand which browsers recognize the acronym tag, though, because some friends in IE6 have reported that it’s working for them, while on the copy of IE6 on my machine, it doesn’t work.
