Here's a neat tool that lets you find every player in NFL history (since 1950) to wear a certain number... It can even allow you search by team.

Play Index Split Finders Are Live!

Posted by Neil on February 19, 2013

We had these in beta for a few weeks, but now we're ready to officially release the following Play Index Split Finder tools:

What can you do with these?

Each is set up in a similar fashion, so let's use the Player Batting Split Finder as an example. For starters, you can tell it to find Individual Seasons, Totals Spanning Seasons, or Career Totals, depending on your preference, and set the usual range of PI options -- year ranges, teams, age, season, active/retired, etc. The big attraction of this finder, though, is on the right side of the form, which allows you to choose split types and stats to sort on.

The split types are any of those which you can find on a player's split's page, and you can just sort on those if you want. For instance, here are the lefty batters who had the most HR against left-handed pitchers in the last 30 years.

Even cooler is the ability to select the "Compare this split to the player's season/career totals" option, which calls up a dialog where you can set a minimum overall requirement (playing-time or otherwise) and the choice to sort by the percentage of the player's total within the given split. An example of this would be, among batters in the last 30 years with 30+ HR in the whole season, who had the highest percentage of their HRs in the second half of the season.

There's also an option to find the difference between the player's stat in the split and his overall number, which works best for rate stats. For example, which hitters had the biggest boost in OPS vs "power pitchers" compared to their overall career OPS?

The Pitching Split Finder works the same way, but it also adds the option to view the output in the form of traditional pitching stats (IP, ERA, etc), the opponent's batting line, or both.

The team finders are similar in function, allowing you to find things like the teams who got the most IP from pitchers age 36 or older, or teams whose leadoff hitters created the highest percentage of their runs.

Needless to say, these examples barely scratch the surface of the kinds of queries you can run with these new tools, so please play around with it and have fun finding incredibly obscure splits! And as always, email us with your questions, comments, and bug reports.

With Spring Training just around the corner, 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.

Organizational Subscriptions can be set up for either an unlimited number of users ($600/year), or for up to five users ($125/year).

There are Two Steps to Subscribe to the Play Index:

  1. Login to or create a Sports-Reference.com account (the same account used to sponsor pages).
  2. Already logged in (or just created an account)? Go to our subscription page to sign up.

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.

Event Finders Now with Batted Ball Type

Posted by admin on January 17, 2013

Event Finders with Batted Ball Types

Did you know that the Pirates gave up the most ground ball bunt singles last year (30) and the Rangers and Brewers the fewest (10)? Or that Matt Cain gave up 10 all by himself.

You can now find information like that on the Play Index Event Finders as we've added the type of batted ball in our DB to the event finder outputs.

All 579 bunt ground ball singles in the MLB last year

Playoff Game Finders

Posted by Neil on January 4, 2013

In anticipation of the playoffs kicking off tomorrow, here's a reminder that you can use the Pro-Football-Reference Play Index to search for playoff games from the past and present.

The Player Game Finder will return all individual games that meet the criteria you select. Try searching for the most yards from scrimmage in a playoff game (Keith Lincoln alert), or use the "Cumulative Season Games" and "Cumulative Multi-Season Games" modifiers to group multiple playoff games in the same postseason or find career leaders.

Meanwhile, the Team Game Finder can help you find team playoff games under various criteria, like the most pass attempts in a playoff game or the biggest point differential by a team that trailed at some point in a postseason game.

You can get the most recent results the morning after the games are played, so by Sunday we should have Saturday's results loaded in. Just be sure to set "Game Type" to "Playoffs" on each tool, and have fun!
