## FanGraphs Pitch Framing

In 2008, when Dan Turkenkopf was the first to quantify the value of pitch framing, he noted that it appeared to be alarmingly important. Bill Letson was similarly astounded when he calculated the size of the effect in 2010. Max Marchi and Mike Fast each took a turn in 2011, finding large and highly correlated catcher values despite using different methods. Other sabermetric luminaries have contributed sophisticated methods and sanity checks, some of which I’ll touch on below. And yet, this terrifically important, seemingly well-established, and impressively repeatable defensive skill has been left out when calculating FanGraphs player WAR and ignored when Steamer forecasts pitchers and catchers. . . until now.

In what follows, I’ll briefly lay out a series of steps for calculating how many framing runs each catcher contributed as well as and how many extra strikes each pitcher was granted (or, in some cases, earned). This much has all been done and clearly described before thanks to Dan Brooks and Harry Pavlidis; that research was updated and expanded upon by Pavlidis and Jonathan Judge. I’ll then compare the values I’ve obtained to the ones created by Baseball Prospectus, StatCorner, and Sports Info Solutions and demonstrate (I hope) that those extra strikes really do result in extra strikeouts and fewer walks. Lastly, I’ll discuss what this means for Steamer forecasts.

### Modeling the Strike Zone

It all starts with the strike zone and I started by using generalized additive models to estimate the probability of a strike in any count, to either left-handed or right-handed batters at each location in and around the plate. On the first pass (shown below), I created strike zones averaged across seasons and, on the second pass, looked for changes in the strike zone by season. The blue contour lines in the images below show where strike calls are a coin flip and the red dashed lines show where we’d expect a 25% or 75% chance of a strike. If you’re read Matt Carruth or Jon Roegele, you’ll be unsurprised to see a small 0-2 strike zones (shown in the upper right facets) and large 3-0 strike zones (in the lower left).

### Distributing Extra Strikes and the Case of Ryan Doumit

We can now compare actual strike calls to predicted strike probabilities. I used a logistic mixed effects model (with batters and pitchers as random effects) to split up credit for extra strikes between pitchers, catchers and dumb luck (or, if you prefer, unattributed variance). For now, I left umpires out of the model reasoning that pitchers and catchers each see roughly their share of pitcher-and-hitter-friendly umpires. Also, I’m looking for a model that we can update daily throughout the season and adding random effects quickly adds computational time.

These extra strikes can be roughly translated into saved runs at a rate of 0.135 saved runs per additional called strike. When we do that we find the following highlights and low-lights of (PITCHf/x era) framing history:

2008 Chris Iannetta -26.6
2009 Ryan Doumit -24.6
2008 Gerald Laird -23.9
2014 Kurt Suzuki -22.8

“Negative 57.8 runs?” I hear you cry! Well, Jeff Sullivan asked this same question when confronted with Baseball Prospectus’ estimate of -63 runs for this same Doumit season in an article entitled “How Bad Could a Pitch Framer Possibly Be?” Sullivan noted that Doumit was estimated to have lost 200 runs due to poor framing over the course of his career. For a sanity check on this number, he compared how pitchers fared with Doumit behind the plate relative to other catchers on the same team and found that pitchers had in fact allowed 213 more runs with Doumit.

### Comparisons to Baseball Prospectus, StatCorner, and Sports Info Solutions

The following charts compare our new Framing Runs to the ones provided by Baseball Prospectus, StatCorner and Sports Info Solutions. Each data point is one catcher season. I’ve kept the axes the same across all three graphs so that you can gauge the relative spreads in runs. One thing that jumps out is that Sports Info Solutions is decidedly more cautious in their numbers than the other three systems.

The following tables shows the correlations between the systems from 2010 (the first year of SIS numbers) through 2018 and the year-to-year correlations for catchers from one season to the next. Our model appears to be most similar to the Baseball Prospectus model but all four models are highly correlated. Our model and BP’s model have the highest year-to-year correlations for catchers but, again, all four systems are in the same ballpark.

### xxFIP really works (and so does pitch framing)!

In 2013 Chris Carruthers asked “How can we take a good ERA Estimator like xFIP, and eliminate framing and bias?” To answer this question he created metrics with inputs that are not affected by the umpire call: swinging strike rates, ball in play rates, zone and out-of-zone looking rates (with zones defined by the rulebook rather than by the umpires) and foul rates. Carruthers created expected strikeout (xK%), walk (xBB%) and xFIP (xxFIP) metrics using only these bias-free inputs. I updated these metrics so that their means for each season match the means of pitchers’ actual rates and then asked whether the differences between pitchers’ actual strikeout rates, walk rates and xFIPs and Carruther’s metrics could be predicted by pitch framing.

More specifically, I built regression models to predict the differences between a pitcher’s actual rates and Carruthers’ bias-free metrics based on the pitcher’s framing runs per game (including runs attributed to the pitcher himself, to his catchers and to luck).

If all these saved strikes our model thinks it sees, really do cause a divergence between xFIP and Carruther’s xxFIP in just the way we might imagine, we’d expect every run per game of framing to correspond to 0.92 runs of difference between the biased and un-biased ERA estimators (since 92% of runs are earned).

Fitting linear model: I(xFIP – adj_xxFIP) ~ FramingRuns_ per9
Estimate Std. Error t value Pr(>|t|)
(Intercept) -0.01602 0.004262 -3.76 0.000172
FramingRuns_per9 -0.8884 0.02031 -43.74 0

According to our regression model, each framing run predicts a 0.89 difference (with a standard error of 0.02). Not bad! We might also be interested in how much framing affects strikeout and walk rates.

Fitting linear model: I(BB% – adj_xBB) ~ FramingRuns_ per9
Estimate Std. Error t value Pr(>|t|)
(Intercept) -0.0005538 0.0001919 -2.886 0.003915
FramingRuns_per9 -0.03881 0.0009144 -42.45 0
Fitting linear model: I(K% – adj_xK) ~ FramingRuns_per9
Estimate Std. Error t value Pr(>|t|)
(Intercept) 0.002668 0.0002269 11.76 1.603e-31
FramingRuns_per9 0.03932 0.001081 36.36 2.599e-258

Our models show that each framing run (per game) adds 3.9% to a pitchers strikeout rate and subtracts 3.9% from his walk rate. Or put another way, it adds 7.8% to the difference. What does this amount to in terms of runs? For that, we can use Tango’s kwERA formula:

kwERA = 5.40 − 12 · (SO% − BB%)

Adding 7.8% to the difference between SO% and BB% should add 12 · 7.8% = 0.94 to a pitcher’s ERA. Again, this is consistent with the 0.92 we’d expect.

These regression models gives me confidence that, although the magnitude of our pitch framing numbers seems astounding, it’s not far wrong. Or, in truth, it gives me further confidence since I was already a believer. If you’re still on the fence, I’d recommend reading Mitchel Lichtman’s research which shows that catcher projected to be good/bad framers really do save/cost runs in the way we’d expect.

### Player Projections

With framing numbers now in hand, it’s time to start forecasting. The following table shows a projection for Yasmani Grandal who is expected (by Steamer) to catch 120 games and see 7,599 called pitches (within a 3.5’ x 3.5’ box around the strike zone) in the upcoming season. The “Framing Rates” are Framing Runs per 6000 called pitches and the seasonal weights are how much weight we give to each called strike from that season. The projection is the weighted average of Grandal’s past framing rates with 1000 league average called pitches added to the mix (the “regression towards the mean”). The upshot is that Grandal is expected to save 17.5 runs by virtue of his framing in 2019. His teammates, Manny Pina and Erik Kratz, contribute an additional 1.3 runs of framing to bring the Brewers team total to 18.8 runs.

We use the following three steps to adjust pitcher projections based on framing:

1. Adjust past strikeout and walk rates to what they would have been with typical ball and strike calls. This includes removing any benefit pitchers received due to extra strikes regardless of whether these strikes were attributed to the catcher, the pitcher or plain old luck.

2. Forecast 2019 strikeout and walk rates (in the usual way) using these adjusted strikeout and walk rates.

3. Adjust these forecasted rates based on each pitcher’s projected ability to get extra strikes as well as the abilities of his team’s catchers.

The affects on individual pitcher’s projections are generally quite small. Pitchers who were good at getting extra strikes are projected to continue to get extra strikes going forward so that much is mostly a wash. Pitchers expected to benefit from catchers with soft hands often benefited from these same skilled framers before (meaning that good framing was baked into their numbers already) and, even where their battery mates have changed, they’re only feeling a fraction of that catcher’s contribution to the team.

Nonetheless, here are the pitchers who benefited the most from adding framing to Steamer.

T.J. McFarland ARI 35.0 4.07 4.19 0.13
Jerry Blevins OAK 25.0 4.47 4.60 0.12

We can add this all up and see how this affects the number of runs each team is expected to allow.

Braves -7.3
Giants -6.6
Teams with worse Steamer Projections
team ChangeInRunsAllowed
Mariners 8.8
Diamondbacks 6.3

The Royals, Brewers and Rangers feel the benefit of acquiring Martin Maldonado, Yasmani Grandal, and Jeff Mathis, respectively, while the Mariners get dinged for adding Omar Narvaez and the Diamondbacks feel the loss of Mathis.

Once we’ve estimated how many runs each catcher saved (or, in the case of projections, might be expected to save) we translate those runs into wins and adjust WAR accordingly. We can adjust pitcher WAR by doing essentially the inverse and subtracting out the value of catcher framing. Essentially, we’re shifting runs (and thus wins) between pitchers and catchers since catchers deserve some share of the credit (or blame) for what transpired.

Please see David Appelman’s WAR post for all the details.

## WAR Update: Catcher Framing!

Update: An earlier bug that impacted updated pitcher WAR has now been resolved. The pitcher tables below have been updated to reflect that. Thanks to everyone who pointed out the issue!

I’m very pleased to announce that FanGraphs has finally added catcher framing data to the site, with full thanks to Jared Cross, who you may know as the co-creator of the Steamer projections. We’ve also incorporated catcher framing into WAR.

Including catcher framing in WAR has been a topic of internal debate at FanGraphs for the past half-decade. The problem has never been with the inclusion of framing numbers on the catcher side of things. That’s a fairly simple addition. The problem has always been what to do with the pitchers. For instance, the 2011 Brewers were some 40 runs above average in catcher framing. When you add those 40 runs to catchers, do you subtract 40 runs from pitchers? As it turns out, you do, but those runs are not attributed equally to each pitcher:

2011 Brewers Starting Rotation
Player IP Catcher Framing Framing per 9
Randy Wolf 212.1 -0.45 -0.02
Yovani Gallardo 207.1 7.79 0.34
Shaun Marcum 200.2 7.47 0.34
Zack Greinke 171.2 5.95 0.31
Chris Narveson 161.2 5.12 0.29
Positive framing numbers for pitchers indicate a pitcher was helped by the catcher’s framing ability; negative numbers indicate a pitcher was hindered by the catcher’s framing ability.

While most of the pitchers on the 2011 Brewers benefited from Jonathan Lucroy’s otherworldly framing, Randy Wolf was stuck with George Kottaras most of the time. In this instance, the entire Brewers pitching staff, with the exception of Randy Wolf, was a little bit worse once catcher framing is taken into account than their previous, non-catcher framing inclusive WAR would indicate.

For catchers, you take the catcher framing runs above average, divide by the runs to wins converter, and add it to your existing WAR total.

WAR = (Batting + Base Running + Fielding + Catcher Framing + Replacement Level) / Runs to Wins

On the pitcher side, we adjust FIP by the catcher framing runs above average per 9 innings. If Zack Greinke’s 2011 FIP was 3.00, and he was helped to the extent of 0.31 framing runs per 9 innings, we now use 3.31 in the WAR calculation instead of the original 3.00 FIP. We also adjust the pitcher’s dynamic runs to wins converter. In Greinke’s case, this would increase his personal run environment and also increase the runs to wins converter.

WAR = (((League FIP – (FIP + Catcher Framing / 9)) / Dynamic Runs to Wins Converter + Replacement Level) * IP / 9) * Game Start Leverage / 2

The RA9-WAR calculation has been adjusted in the exact same way.

Let’s take a look at how the inclusion of catcher framing has changed things:

Now you know everything there is to know about how we added catcher framing to WAR. Please note the following:

• Catcher Framing (abbreviated as FRM) is available on the leaderboards and player pages in the fielding sections.
• WAR has been updated with catcher framing data everywhere WAR is available on the site.
• Catcher Framing data is available in batter and pitcher sections of the leaderboard as a custom stat.
• Fielding (the WAR component) now includes Catcher Framing runs above average.
• Steamer projections and depth chart projections both include projected catcher framing for catchers and pitchers.

## We Added Minor League Level to THE BOARD!

We’ve added a column on THE BOARD called “Current Level” displaying the most recent minor league level the prospect has played at or has been transacted to.

The process of programmatically determining a prospect’s current level is slightly less straight forward than it might seem. For example, Vladimir Guerrero Jr. is currently a Blue Jays non-roster invitee, so his Minor League Baseball stat page has him listed as Blue Jay, but he hasn’t played a MLB game.

To mitigate problems like this, we are using a combination of our game logs and MLB’s transaction list, along with some logic to determine the prospect’s level. Here’s the summary of the logic:

• If the prospect hasn’t played in the majors, he cannot have the majors as his level.
• We look at the most recent minor and major league games the player has played and find the game with the most recent date.
• We look at the most recent transaction MLB has listed.
• We compare the transaction and last game to determine which is more recent and use that for level, with consideration of the MLB debut.

This logic will prevent prospect non-roster invitees in Spring Training from displaying as being at the major league level. The transaction and game log approach will provide some robustness against any errant transaction data. Since this is programmatic, there isn’t any judgement on whether an assignment is temporary, like a rehab stint would be.

If you notice any errors, there could be a delay because the data processing runs overnight, but if it persists, please let us know.

## Introducing Our New Contributing Writers

In January, we put out an open call for contributing writers. The response we received was overwhelming. Over 500 people submitted applications, and we are very grateful that so many smart, passionate baseball writers wanted to be a part of what we do here. It made for some really difficult decisions (and a rather long hiring process), but we are very excited to welcome six new contributors to our ranks.

A quick note to those who applied but weren’t hired: please keep writing. A number of people who have come to work for the site weren’t hired on their first go, but kept getting reps elsewhere on their way to making us regret having passed them by initially. Just because there wasn’t a home for you at FanGraphs this time around doesn’t mean that there won’t be one later, and in the meantime, public baseball analysis will be made better by your good words and good work.

And so, without further ado, allow me to briefly introduce the writers whose work will be debuting on these electronic pages soon.

Rachael McDaniel
Rachael has written at Baseball Prospectus, Vice Sports, and The Hardball Times, authoring work encompassing a whole range of baseball topics past and present. Rachael is currently in the creative writing program at the University of British Columbia in Vancouver, and following the conclusion of the academic year, will assume the role of managing editor of The Hardball Times in addition to writing at FanGraphs as a contributor.

Devan Fink
Devan has spent the last two years as a featured writer at Beyond the Box Score and the previous four years blogging for his own website, Cover Those Bases. He loves analyzing the latest current events and trends in baseball, ranging from the most minute aspects of the game to the largest, most impactful tendencies league-wide. Outside of baseball writing, Devan is currently a senior at James Madison High School, where he serves as an editor-in-chief of the school newspaper, The Hawk Talk, and as the captain of the debate team. He will be attending Dartmouth College next fall, where he plans to study quantitative social science. Devan resides in Northern Virginia with his parents, brother, and his four-year-old cockapoo, Ike.

Sung Min Kim
Originally a broadcast journalism student at Maryland, Sung Min took a sports writing class as a fun elective and went from there. Since his debut at The Hardball Times, he has been writing about the Yankees at River Avenue Blues. He has also written about Asian baseball for publications like VICE Sports, The Sporting News, Baseball Prospectus, and The Athletic. Sung Min will explore different aspects of Asian baseball while also writing about major league subjects.

Ben Clemens
Cardinals fans may recognize Ben as a writer from Viva El Birdos. He always wanted to play baseball and be a famous writer growing up — he got ‘baseball’ and ‘writer’ at least, though he’s still working on ‘play’ and ‘famous.’ Working in financial markets made him interested in the decision-making and game theory aspects of baseball; he’s now answering the truly important questions, like whether Matt Carpenter should swing more on 3-0. He lives in New York but will soon be moving to San Francisco.

Audrey Stark
Audrey attended her first MLB game in June 2003 with her Girl Scout troop. While watching Albert Pujols through binoculars from an upper section of Busch Stadium II, she realized that baseball was the best sport on the planet. Audrey began writing for SBNation in 2016 at Beyond the Box Score; she has also contributed to Viva el Birdos and Federal Baseball. She has a degree in political science.

Octavio Hernandez
Once a beat writer in the Venezuelan Winter League before becoming the assistant GM for Leones del Caracas in that same league, Octavio currently works for Diablos Rojos del Mexico as the chief of the Advanced Metrics department. Now he’ll return to his roots as a writer, focusing on Latin American major league players along with providing some insight into what’s going on in the Mexican League and the Caribbean Winter Leagues. He is a man with a mission: to help Latin American baseball get on board with advanced metrics. He hopes you will join him on his ride.

You’ll begin to see work from these six writers appearing at FanGraphs soon. We hope you’re as excited for them to get going as we are.

## Why Not Both? THE BOARD: Scouting + Stats!

We decided to make a leaderboard that combines THE BOARD! with our Minor League Leaderboards. There are a ton of new features to review, but if you are the type of person that attempts to assemble furniture without reading the instructions, here’s the link:

https://www.fangraphs.com/prospects/the-board-scouting-and-stats

If you are still with us, we have a lot to cover. This combined leaderboard is similar to a feature we tested on our prospects landing page where the prospect list that Eric and Kiley have compiled is joined with our minor league stats.

Here’s a list of the new features:

• THE BOARD: Scouting + Stats!
• Added the ability to select multiple seasons
• Added the ability to filter by organization
• Added three new league filters: Upper (AAA/AA), Mid (A+/A), and Low Levels (A-/R)
• Revamped Custom Reports
• Your custom reports can be displayed as a tab (blue instead of green) on the leaderboard.
• The interface to add and change stat columns is all-new.
• You can choose to include row numbers in your report.

### THE BOARD: Scouting + Stats!

You can think of the combined leaderboard as a Venn diagram or a SQL inner join. Minor league players who are not in the selected prospect list will not appear on the combined leaderboards. Likewise, players without any minor league stats (Shohei Ohtani) are not available on this leaderboard.

Unforunately, you also can’t mix batting and pitching stats on the same leaderboard; these are still different data sets (pictured in the above data join diagram). The scouting report data is position agnostic, but the stats data still behaves like our traditional leaderboards, so you can only combined one stat data set with the scouting data set.

The filters are organized by the source of data they control. For example, scouting grade filters are on the scouting tab, while the playing time filter appears on the stats tab.

Since there is the possibility of duplicate filters for position and organization, we have those two filters located under common filters. Both filters use data from the scouting data set, so you could look at the stats of a traded prospect regardless of what system he accrued those stats. The position filter uses Eric and Kiley’s classification, instead of what position our leaderboards have for a player. This might change in the future if we deploy more advanced control options.

Important Notes:

• A leaderboard can only contain either batting or pitching stats.
• Right now, we are only including scouting information from prospect lists. There are plans to include draft and international players in the future.

The Minor League Leaderboards have been redesigned, and we added a few new features. We added the ability to select multiple seasons and either aggregate them (default option) or have them split into multiple years. The “Split Seasons” option splits the player’s stat line by both season and team. An organization filter has been added so you can group stats across levels by the MLB organization instead of just being able to filter using the affiliate teams. We also included a few new league filters that groups tiers of levels: Upper (AAA/AA), Mid (A+/A), and Low Levels (A-/R). These will allow you to aggregate stats across those tiers.

We don’t always carry legacy tools, but we are keeping the old minor league boards around at least for a bit. These will be available in the leaders menu, but they won’t be the main link. You should be aware these might not always exist, and we are not going to continue developing them. If you are using them as a data source for research, please considering migrating to the new Minor League Leaderboards.

### Custom Reports

The Custom Reports for the combined leaderboard and the Minor League Leaderboards are all-new. While FanGraphs has well-established stat groups: Standard, Advanced, and Batted Ball, combining scouting and stats data left us with too many combinations to include everything; this is where the new custom reports come in.

Like the old custom reports you are able to create a leaderboard with your choice of stat columns, filters, and players, but now they can be displayed as blue tabs on the leaderboard for quicker access. You can create a new report by clicking the plus button.

All of your reports for the specific leaderboard are housed in the Custom Reports dialog box accessible from the Custom Reports button on the data grid. In that dialog box, you can manage your reports including loading them into the tab bar and making them load in to the tab bar by default.

The interface to change the stat columns on the table is also completely new. You can either double click (long press on mobile) or drag/drop stats to customize your report. The columns are organized by the default tab they appear in. Once again, you can’t mix batting and pitching stats, but mixing scouting columns is cool.

Important notes:

• Each report has an owner.
• The owner is the only one who can modify, save, or delete that report.
• You also must be signed into your FanGraphs account to modify, save, or delete any report.
• However, every report is viewable by anyone if you have the URL with the report id in it.
• You can create a copy of a report by viewing it and clicking to create a new report.
• “Edit Table” allows you to choose different columns on the table.
• Turning off the “Include Filters” button allows you to create a report that is agnostic to filters including custom players. This can be used if you want to create a tab with certain stats acting like native tabs.
• Your older minor league reports are still available, though you won’t be able to save them.

### Future Notes

• We are in the process of determining how to handle the “current” level for prospects. It’s an addition we want to add to THE BOARD, but it’s not ready for this update.
• While these tools are conceptually connected, they don’t share data between them, so going from the Minor League Leaderboards to THE BOARD: Scouting + Stats! won’t retain settings and filters.
• Custom Reports “belong” to the tool you created them in, so you can’t make one in the leaderboards and use it with the combined leaderboard. This might change in the future, but it’s a restriction for now.

## FanGraphs is Hiring! Seeking Site Contributors

Update: The submission deadline for applications has been extended to Friday, February 8.

As the 2019 season approaches, I’m pleased to announce that FanGraphs is now accepting applications to join our staff as a contributing writer.

Contributors typically write three times a week. Familiarity and comfort with the data here on FanGraphs is a requirement, but just as importantly, we’re looking for writers who can generate their own ideas and questions while providing interesting analysis or commentary on the game of baseball. From free agent signings to statistical analysis, teams’ top prospects to in-game strategy, we endeavor to cover it all, highlights to lowlights. Sometimes we do that with a bit of silliness; other times, we’re more serious. But what all of our work has in common is a commitment to asking interesting questions and using rigor, creativity, and the latest analytical tools to find the answers for our readers.

This is a part-time, paid position. Prior writing experience is strongly preferred, though the bulk of that experience doesn’t necessarily have to be of the baseball variety. We know baseball analysis is more interesting and complete when diverse perspectives and voices are brought to bear on the questions and trends in today’s game, and encourage writers of all backgrounds and identities to apply. When applying, please include samples or links to work you’ve published previously, or some new, original content you feel best demonstrates your writing abilities and interests. You may also include a resume, but it is not required for the initial application. Please send us an email at wanted@fangraphs.com with your application materials, using the subject line “FanGraphs Writer Application – 2019.” The subject line is important, as it helps us keep all of the applications organized and ensures that yours does not slip through the cracks.

If for some reason you are unable to submit your application using the wanted@fangraphs.com e-mail address, simply fill out a contact form with the same subject (“FanGraphs Writer Application – 2019”), and you will be provided an alternate e-mail address for submission.

However you send us your application, please do so by Friday, February 8.

If you feel like you’d be a good fit as a contributing writer for FanGraphs, please drop us a line. We cannot promise to respond to every application we receive, but we’ll make sure every applicant receives serious consideration.

We look forward to hearing from you.

## 2019 FAN Projections!

The 2019 FAN Projection ballots are now open!

Before you can project any players, you’ll have to select the team you follow most closely towards the top of the screen. If you don’t really follow a team, just pick one. You’ll only have to do this once.

After you’ve selected a team, you can begin projecting players. There are nine categories of interest for pitchers and 10 categories for position players. Pick the values in the drop-down boxes closest to what you think the player will do in 2018. Hit the submit button and you’re done! If you made a mistake, you can always go back and change your selection at any time.

Please note that everything is a rate stat. You’re projecting 2B+3B, HR, SB, and Fielding as a measure of 150 games (basically a full season). The player’s previous stats are shown per 150 games in the projection ballot, too. This will make changing playing-time projections much easier, as you’ll only have to change the games played portion.

That’s really all there is to it. You can filter players by team or, if you go to the player pages, you can project players individually. If you want to see all the players you’ve projected, you can click on the “My Rankings” button, which will show you only what you specifically projected a player to do.

FAN Projections will appear on a player’s page after five ballots have been submitted for him.

If you do notice any issues, please let us know.

## We Upgraded Our Site’s Search Bar

At last week’s Winter Meetings, we redesigned our search bar functionality, and we are launching it today. The search bar location and the main function haven’t changed. The search bar is in the same place, and by default has the most-viewed players. It allows you to search players and blog articles. We did a pretty significant under-the-hood update that returns more relevant results, and while we were at it, we made some interface updates.

If you are interested in the details:

• Players results are weighted by a combination of name match and the number of recent views.
• Active players are in bold. The partial match of a search term is also underlined the player’s name.
• Articles can be searched in a separate window. They are weighted by term matching, number of views, and recency.
• For now, we’ve only included main page articles, not articles from all of our the blogs. The other blogs will be added in the future.
• We included Team Pages in the results!
• The search is also available as a full page: fangraphs.com/tools/search

## We’re Relaunching the Community Blog

If you have ever wanted your writing to appear on the pages of FanGraphs, do we have good news for you!

After a brief hiatus, we are relaunching the Community Research page, a blog that features articles from our readers. This means you, your friends, your grandma, basically anyone with a (free) FanGraphs account can submit some baseball words to be run here on the site.

There are a few rules, of course. There are always rules:

• Every article is subject to approval. While submitted works represent a range of topics and exhibit varying degrees of polish, they do need to be appropriate, and meet a baseline of readability and relevance.
• Your submission must be your original work. Please only send us pieces that you have written.
• That said, your article does not necessarily have to be exclusive to FanGraphs. Have a piece from your own blog that you think would fit well here? Send it on over for approval. Just let us know where else it has appeared.
• You may submit a maximum of one article per week. We’d love to run every worthy article we receive, but realistically, we can’t. We appreciate your understanding.

That’s about it. If you have submitted pieces in recent months while the blog was on hiatus that did not run, and you still feel they are relevant, feel free to submit them again. We are starting with a fresh slate of submissions going forward.

If you don’t have a FanGraphs account (seriously, it’s free), you can register here.

Once you have an account, you can submit a post here.

We’re looking forward to sharing your research.
