Subscribe to the Play Index!

29th March 2013

Opening Night is Sunday, so be sure to make the Baseball-Reference Play Index a part of your baseball experience for the 2013 season!

What's the Play Index? It's a set of research tools that allow you to create customizable queries on our database, save the results, and share them with others. Using the PI, you can:

  • Search full-season or multi-year totals to find your own custom leaderboards - Look at the entire history of baseball from 1871-2012 with every year, team, and position available, or filter the results in a vast number of ways: by specific years, by age, by first six seasons or last ten seasons, by American League only, by Cubs only, by switch-hitters, by catchers, by outfielder or infielder, by year of debut, but active or retired, by Hall of Famer, by height and weight, by living or deceased, or by a range of common statistical categories. Then sort the results by any common statistic, by the teams with the most players matching that category, by players with the most seasons matching that category, or by most recent, youngest, oldest, final year, or year of debut, and others.
  • Search player game totals - Filtering on any of a dozen or more choices, search for games on a single player level, or on any batter from 1916-2012, or on any pitcher. The same can be done for Team Batting or Team Pitching Totals.
  • Search player games looking for the most consecutive games matching a particular set of criteria - This can be done either on a single player level or on any batter in the last 97 years or on any pitcher. The same can be done for Team Batting or Team Pitching Streaks.
  • Search the records of a specific player - Output a detailed summary and play-by-play list of all events of a specific type from a single year or an entire career. For example, you can see all of Harmon Killebrew's triples or even his outs to the second baseman.
  • Search Batter vs. Pitcher Matchups - This tool presents a complete sortable list of batter or pitcher with totals for every opponent they faced by career or by year. Clicking on the player's name will lead you to a detailed output of their head-to-head plate appearances.
  • ...And more!

Personal Subscriptions to the Play Index still cost just $36 for a year, $6 for a month, or $2 for 24 hours. Subscriptions may only be used by a single user, and there are discounts for users sponsoring at least $35 in pages.

Our Always-Available Free Trial: Non-subscribers can use the PI's features as much as you like. However, your outputs will be restricted to a limited number of results.

The Play Index comes with a money back guarantee. We will gladly return the unused portion of any Play Index Subscription should you be dissatisfied with the Play Index.

So go ahead, give the Play Index a try -- we're confident that once you start using it, you'll wonder how you ever got along without it.

Adjustment to WAR Replacement Level

29th March 2013

In a move to 1) reduce the number of negative WAR long-time players and 2) create a bit more consistency between our version of WAR and that on FanGraphs.com, we have agreed with them (their article about this change) to move the replacement level to .294 or 1,000 Wins for current seasons (30 teams * 162 games * (.500 - .294) = 1000). Pre-30 teams leagues will likewise be adjusted. Our previous Replacement Level was .320 or 875 wins, so we are now giving out 125 more wins than we were before. FanGraphs previously had a .260 replacement level, so they are going from 1,166 wins to 1,000. The net result is that these adjustments are given to players in a manner proportional to their playing time regardless of their quality of play.

My Answer to “I Don’t Like How Complicated WAR Is and How It Is Constantly Changing.” “WAR is Like GDP for Baseball”

29th March 2013

Some of the common critiques of the Wins Above Replacement framework include: 1) Why do FanGraphs and Baseball-Reference.com have such different numbers, 2) How can we trust it when the numbers change, and 3) How can we trust it when I can't calculate it?

For the first question, our announcement today of a consistent replacement level between FanGraphs and Baseball-Reference.com has done a considerable amount to bring our two methodologies into alignment at least on the question of how big of a basket of WAR to hand out to players each year. Previously, FanGraphs allotted nearly 300 additional WAR due to a much lower replacement level. Our meeting in the middle has erased this difference to zero.

For the next two questions, I would point to a very widely quoted and very widely used statistic from economics, Gross Domestic Product (GDP). Here is the Wikipedia article on Gross Domestic Product. I'm going to argue that WAR is essentially GDP for baseball.

2013 Spring Training Stats W/ Quality of Opposition Measure

26th February 2013

We've never included Spring Training stats on the site before, but decided to add our own take this year, so we now have spring training stats on the player and team pages and on a league register page, so you can see every player in camp on one page.

One hard thing about spring training is that you've got a very wide variety of players in camp. Veteran major leaguers, AAA, AA, and even low-A ball players. A player hitting .400/.500/.600 against A-ball competition is a lot different than one who does that against MLBers (though truth be told the sample sizes are so small as to not tell us much definitively). To give you a feel for the level of competition we've provided an OppQual column that is 1-10. Each opponent for each PA for that batter or pitcher is graded between 1 and 10 based on the level or average level (weighted by IP or PA) they played at last year.

  • 10 - MLB
  • 8 - AAA
  • 7 - AA
  • 5 - High A (Cali or Carolina)
  • 4 - Full-Season A (Midwest and SALLY)
  • 1.5 to 3 - Rookie or Short-season
  • 1 - for pitchers if the opposing batter is a pitcher

So a player over 9 is facing mostly MLB guys while someone under 9 is facing mostly minor leaguers. Players like John Lackey in 2012 or Yu Darvish in 2011 who did not play in an MLB affiliated league are simply excluded from the rating.

Player Pages - Spring Training Stats appear at the top of major and minor league player pages.

Team Stats: 2013 Atlanta Braves Spring Training, these are all linked from the site front page.

League-wide Stats: Batting Register and Pitching Register. These tables are sortable, so you can look up current leaders if you like.
