The Stumble to 500,000 MLB Errors

Posted by admin on August 30, 2012

This is utterly random, completely meaningless and less than 100% accurate, but earlier this summer I noticed, that MLB was nearing 500,000 errors since 1876. We track all all-time stats on our seasons index. So as the half million mark approached, I decided to add a counter to the front page of the site. We'll also try to pinpoint the offending player on the day the milestone is broken.

Are we 100% certain this will actually be the true, honest-to-god, real 500,000th error since 1876? No, it undoubtedly isn't as there are lots of accounting discrepancies in the "official" record, especially in the fielding stats. I'm sure Elias has a different number and in our case our player-by-player and team stats don't even match up on error, putout or assist totals. For pre-1970's results, fielding records were mostly an afterthought and no effort was made to make sure they balanced at the end of the season. But it's a fun milestone, so we're going to track it.

UPDATE: One other issue that may affect things is that some errors are overturned at a later date, so even on the night we deign an error the 500,000th it may actually move up or down the last next week when mlb reviews borderline scoring calls.

So always remember this milestone is for fun and is accurate to the best of our ability, but in no way 100% accurate.

The Relationship between WAR and Team Wins

Posted by admin on August 8, 2012

This question came up on the SABR-L newsgroup for SABR members.

I'm almost reluctant to ask this seemingly obvious question, but I'm puzzled:

What does Wins Above Replacement Value mean in terms of team success? Or put another way, if a team consists of nothing but replacement players, or -0- value WAR players, how many games does that theoretical team win? Surely not -0- games. Nor 81.

Here was my reply:

We have a pretty exhaustive intro to the metric here.

http://www.baseball-reference.com/about/war_explained.shtml

A replacement level team is set on our site to win 52 games in the year, so there are about 30*162 * (.500-.320) = 875 wins above replacement available for the league as a whole.

Here is an example conversion of WAR to team wins.  

The Phillies batters have 9.8 WAR, pitchers 6.1 WAR, and they've played 110 games.  A replacement team would win 110*.320 = 35.2 of those games.  Using WAR, we estimate the Phillies to have 9.8 (WAR batting) + 6.1 (WAR pitching) + 35.2 = 51.1 wins compared to their 50 actual wins.  51.1 is right in between their actual 50 and their pythagorean 52 wins.

Using a team playing well, Texas has played 109 games, so the replacement team is at 109 * .320 = 34.9 wins.  They have 13.7 batting WAR and 14.7 pitching WAR or an estimate of 34.9+13.7+14.7 = 63.3 wins.  They actually have 64 with a pythag of 62.

Cumulative Team WAR is not constrained to match up with team wins and losses, but it definitely should match up to team wins and losses and team pythagorean wins and losses.

How To “SHARE” S-R Stats

Posted by Neil on August 8, 2012

If you've spent any time at our sites, you've probably seen the "SHARE" command in red text above a table of stats... but maybe you didn't know what that did, or have forgotten how to use it. No worries -- here's a quick rundown of the features you can access by clicking "SHARE":

  • Customize rows & columns - Sharing lets you delete certain rows/columns that you don't want to include in your table. Just click the round 'x' button to delete a specific row/column, or the arrow 'x' to get rid of everything to the right (columns) or directly below (rows) the row/column in question.
  • Export as an HTML table - Clicking 'html
    ' gives you code to embed the table onto your site (you can even choose to keep S-R's inline style formatting).
  • Get a link - Choosing Link URL creates an SR tiny URL specifically for the table you created, which can easily be sent to others via twitter or directly linked at your blog.
  • Export as bbcode - This option lets you copy-and-paste the table into most bulletin board formats.
  • Export into a javascript widget - This will give you code to embed the static table on your site via a js widget. (Note: The 'Embed' option next to 'SHARE' allows you to do this as well, but as a constantly-updated table instead of a static one.)
  • Export as an iframe - For those who prefer to embed the table within an inline frame.
  • Export into preformatted text or CSV
  • Convert table to Wiki formatting - This will turn the table into a format suitable for sites like Wikipedia.

These features are currently active at all Sports-Reference sites except Hockey-Reference, which will be updated either this week or next. Happy sharing!

With the trade deadline coming up tomorrow, you might be interested to know how often a given franchise has traded with every other MLB team in its history.

Luckily, you can find a list of those trades using our Franchise Trade History feature. (Here's a great example of the kinds of searches you can run using this tool.)
