Subscribe to the Play Index!

31st May 2012

In case you don't already know about Baseball-Reference's 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 1918-2012, 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 95 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!

Cool Play Index Event Finder Tricks

23rd May 2012

The Event Finders are an underrated set of Play Index tools:

Batting by Team / Pitching by Team
All-Star Batting / All-Star Pitching
Postseason Batting / Postseason Pitching

You might know that they allow you to search for individual plays matching certain criteria, but there are some tricks that even experienced PI users aren't aware of.

For instance, say I wanted to find the all-time career leaders in HR at Chase Field. You could get that using the Game Finder:

1 Luis Gonzalez 87 Ind. Games 394 341 150 18 0 95 177 44 40 .440 .501 1.328 1.830 1 5 7 3 9
2 Steve Finley 75 Ind. Games 321 279 140 15 5 84 163 36 28 .502 .558 1.495 2.052 0 3 6 3 3
3 Chris Young 63 Ind. Games 282 255 101 12 0 67 114 23 52 .396 .445 1.231 1.676 1 2 2 1 3
4 Mark Reynolds 55 Ind. Games 230 203 97 11 2 60 114 25 54 .478 .539 1.438 1.978 0 0 2 2 2
5 Justin Upton 56 Ind. Games 243 216 108 12 3 57 108 21 38 .500 .539 1.375 1.914 0 4 2 2 2
6 Matt Williams 46 Ind. Games 207 193 86 8 1 48 94 13 23 .446 .478 1.244 1.722 0 1 3 0 2
7 Jay Bell 45 Ind. Games 207 178 89 10 3 47 93 23 25 .500 .559 1.382 1.941 3 1 0 2 1
8 Tony Clark 38 Ind. Games 142 129 65 4 2 43 73 13 26 .504 .549 1.566 2.115 0 0 5 0 1
9 Chad Tracy 41 Ind. Games 166 146 70 7 1 42 82 14 17 .479 .521 1.404 1.925 1 3 2 2 4
10 Shawn Green 29 Ind. Games 126 114 56 7 0 33 70 9 17 .491 .524 1.421 1.945 0 2 1 1 5
Provided by View Play Index Tool Used
Generated 5/23/2012.

But you can also get that using the Event Finder, searching for HR by all teams from 1998-2012 at Chase Field:

Luis Gonzalez	95
Steve Finley	84
Chris Young	67
Mark Reynolds	60
Justin Upton	57
Matt Williams	48
Jay Bell	47
Tony Clark	43
Chad Tracy	42
Shawn Green	33

And unlike the Game Finder method, you can also break it down into HR against lefties and righties:

vs RHP
Luis Gonzalez	74
Steve Finley	56
Chris Young	52
Mark Reynolds	44
Justin Upton	39
Jay Bell	36
Chad Tracy	36
Tony Clark	33
Matt Williams	27
Stephen Drew	24

vs LHP
Steve Finley	28
Luis Gonzalez	21
Matt Williams	21
Justin Upton	18
Mark Reynolds	16
Chris Young	15
Shawn Green	13
Junior Spivey	12
Eric Byrnes	12
Conor Jackson	11

Basically, you can split out the stats based on any of the red text items you see in the box on the page, including hit locations, bases occupied, score margin, and a lot more.

You can even get a composite stat line for all of the plays, so you can use this to find incredibly obscure splits like what left-handed DHs have hit in high-leverage situations at Jacobs Field over the past 3 seasons:

263 59 14 0 11 28 0.260 0.342 0.467 0.809

Remember, you can do thins not only with teams in the regular season, but also the postseason, the All-Star Game, and for individual players as well.

The Lengths Researchers Go To

18th May 2012

The following is a report from Richard Malatzky a stalwhart researcher with the SABR biographical committee. There are about 5-10 people on the SABR biographical committee who tirelessly do research to locate late 1800's early 1900's ballplayers. They pore over all kinds of records for no pay to get these records right. We owe them a tremendous debt of gratitude.

With the eventual release of Pennsylvania Deaths Register last month I thought I might find Morelock (ed. for the last 12 years, we've just called him Morelock) but it didn't happen.

I had been searching for him for about 35 years. It turns out that Philadelphia which is where he was from had several Morlocks but no Morelocks, not a one.

The Sporting Life mostly called him Morelock but Morlock did appear a couple of times.

(In the census) There was a Henry or Harry Morlock born November 1869 in Philadelphia and he was a weaver. I figured that this must be him. But what about A Harry? I saw him called A H Morelock a couple of times in Sporting Life. His father was Adam and son was Harry A.

He played several years around Philadelphia and appeared with the Phillies in 1891 and 1892.

Harry was in the census in Philadelphia up to 1930 and appeared in the Suburban phone book in Upper Darby Pa after 1940.

I searched his daughter's name Lillian and surprisingly found her obituary age 106. Lillian G Rathburn. I searched her name and surprisingly found a legal document from Atlantic City NJ that gave her father's date of death April 21 1949 and place Atlantic City. All of his relatives were listed and combined with Lillian's obit I was able to find the addresses of some relatives.

I found that the only newspaper available for an obit in Atlantic City was the AC Press. On a visit to AC, I searched the microfilm and no obit.

Today, I received an e-mail from a great great grandson of Harry who confirmed that this was the ballplayer. He has a picture of him in uniform.

WAR Comparison Chart -

Colin Wyers was kind enough to fill this out for WARP, so I've added WARP to the comparison chart and also split it off onto its own page for easy linking. If you want to know why numbers are different from one site to the next, this explains why.

WAR 2.1, Fixed Runs to Wins for Pitchers and More

9th May 2012

WAR 2.1, WAR Explained

As some noticed in our last update to WAR. Pitchers were being significantly bumped up in value. This was due primarily to a change in our runs to win calculation. After some consultation with noted, anonymous sabermetricians Tom Tango and Patriot, we worked out a more sophisticated approach that still accounts for the player's effect on the run environment, but doesn't overvalue the contribution of stellar pitchers. We've added a new page to run through the changes we've made when converting from runs to wins. Converting Runs to Wins.

There are a few other changes that have been made as well.
