A New Chapter at Sports Reference

1st April 2018

I've been at this for 18 years now. Baseball-Reference.com launched in early April of 2000, and 18 years is a long time. We've gone from pre-formatted plain text tables to html tables, through various logos, and several redesigns involving mobile designs. Along the way, the only consideration has been what would work best for the user. That's why, after months of extensive research, I'm very pleased to announce:

2018 WAR Update

15th March 2018

As you browse Baseball Reference, you might notice some subtle changes to WAR figures on the site. There are four main reasons for this:

  1. Park factors for recent seasons have been re-computed to be three-year rolling averages. For instance, 2016 Park Factors now encompass 2015-2017. This is something that needs to be done when seasons end.
  2. We've incorporated restated and expanded fielding statistics from Sports Info Solutions. SIS's Defensive Runs Saved forms the basis for our Defensive WAR calculations since 2003. From 2011 on they recalibrated data using their timer measures to measure ball hang time. There was also some recalculation based on changing shift methodology. Though we're now publishing their catcher framing stat (Strike Zone Runs Saved), we have not incorporated it into WAR at this time.
  3. Pitchers who received time as position players (whether PH or in the field) are now being treated as part-time pitchers and part-time position players. Previously we treated them as full-time pitchers. Some pitchers like Red Ruffing, Bob Lemon and Jim Kaat appeared in many games as a position player, pinch hitter or pinch runner. We used to credit these PAs as pitchers, which overvalued their offensive contributions. To handle this, we compute a percentage of time as a non-pitcher and make an adjustment.
  4. Also, we have incorporated a good deal more Retrosheet data which has affected the years we can compute more advanced fielding and baserunning measures. We're now able to roll these measures back to 1953. Another important change is that with Retrosheet gamelogs back to 1908, we can now use their IP data back to that year to get starter/relief IP splits. Some pitcher WAR changes for 1908-12 are due to WAR now being calculated using gamelog IP rather than the "official" total listed on the player's stat line. The biggest difference here was the appropriately named Bugs Raymond. The "official" record credits him with 324.1 IP that season, but the gamelogs come out to 304.1, which significantly impacted his WAR calculation (see below). For further reading on discrepancies between "official" records and more recently produced gamelogs, please read this excellent explainer by Retrosheet's Dave Smith.

For further details on WAR and its calculation, please see this WAR explainer.

Major Improvements to NBA Finals Box Scores

24th August 2017

At Basketball-Reference, we have every box score in NBA history, including the playoffs. However, for many years, we don't have all statistical categories filled in in these box scores. We have recently taken a major step towards remedying this issue with our playoff box scores. We now have nearly complete box scores and series cumulative boxes for every NBA Finals series in NBA history.

Massive Improvements to NCAA Tournament Box Scores

23rd August 2017

As you may know, our College Basketball site has every box score in NCAA Tournament history. However, many of these box scores were missing certain categories. For instance, blocks, steals and assists were not officially-tracked college basketball statistics until the mid-1980s. And in the tournament's earliest years, only scoring and shooting were officially recorded. Still, we were missing large swaths of available data on these games. However, thanks to the research of Sean Burrill, we have made huge improvements and now have nearly full coverage of all statistical categories for all NCAA Tournament games since the field expanded to 64 teams in 1985.

New Search Criteria Added to Basketball Reference Player Season Finder

1st August 2017

We have added a few new search options to the Basketball Reference Player Season Finder

These additions can be found in the "Search Award/Honor" dropdown on the search form. Previously, you could run searches for major award winners and All-NBA or All-Rookie players. We've now added the ability to search for All-Defensive Players. Additionally, rather than searching for just First or Second team players separately, you can can now search for both First and Second team in the same search. Here are a few examples of new searches you can run:

---Worst Defensive BPM by a First-Team All Defense Player

---Fewest Win Shares by an All-Rookie player (1st or 2nd team)

---Youngest players to make an All-NBA team

We hope you enjoy these additions. Please let us know if you have any questions

B-R Redesign Update March 9, 2017

9th March 2017

I want to give a short update as to where the new redesign stands. We have fixed we believe all of the bugs (that didn't already exist) in the play index. There are a few open issues in the register section. We have incorporated many of the suggested changes to the site from users who were experiencing issues.

Open issues

  • The register has a few open bugs
  • The in memoriam is not yet showing our non-players
  • There are a few bullpen style and administrative issues.
  • There appear some issues relating to Internet Explorer hanging in a way we can't reproduce.
  • We are working on publishing the 2017 spring training stats, the projections, and the foreign leagues already underway.

We are working through all of these and expect to be 100% ready to go on Opening Day.
