New Bot Filtering and Content Delivery Network for Sports Reference Sites

7th October 2022

Our devops department finished our move from AWS's Cloudfront Content Delivery Network (CDN) to Cloudflare's CDN this week. This will be undecipherable technical jargon to most of you, so I'll explain what it means.

When you request a page or file from the site, the request first goes to a CDN that is located geographically close to you and if a neighbor of yours (within several hundred miles) has requested the page earlier in the day, you'll get a cached copy of that page much faster than you would otherwise. If your neighbors are lame and don't use our site or just haven't visited that page, then the request will be passed on to our servers and we'll send you the page.

This has many advantages in that it takes a load off our servers and also makes things faster in general for our users the more the sites are used.

Cloudflare also includes bot filtering with this offering. It actively searches for badly behaved bots and proactively blocks them from our site. We are now utilizing this feature because we get scraped. A LOT. And if your bot is badly behaved then we don't want you impacting the performance of the site for our other users. We've gotten a number of emails around this this week as people who have been scraping us have found themselves blocked.

As of today, this filtering will remain in place for our:

  • Soccer/Football
  • Basketball
  • Hockey
  • College sites

We are turning off the active bot filtering on our baseball and pro football sites at this time. We will re-enable bot filtering the week after the end of their respective seasons.

What is a well-behaved bot? Please see our Data Use page and our Bot Traffic page for guidance. Note that if you are blocked by our servers, the blocks reset after 24 hours, so with some more polite settings on your bot you may be able to try again the next day.

We can not provide an API (per our data licensing agreements), and you should not view as a data provider (on par with SportRadar or Genius Sports). This is a role that we do not and can not support with company resources.

Exciting Update to the Team Game Finder on Stathead Baseball

13th July 2022

We've rolled out a new update to Stathead Baseball, giving the Team Game Finder some cool new features.

The most exciting new addition to the Team Game Finder its a set of new search types that give you the ability to answer more questions than ever before. As with the Player Game Finder, we've added the option to search for combined statlines from all the games that match your search. You can now look up team stats in home or away games, wins or losses, and much more.

We've also added a search type that gives you the option to look for the most matching games from multiple seasons. Previously, you only had the option to look up matching games from a single season.

Want to give it a try? Here are some questions to get you started:
What team had the most road HRs in a season?
What team has the most all-time road wins?

Lastly, the new upgrade brings smoother performance and faster searching to the tool, meaning it's never been easier to answer your questions about team game stats. If you're a Stathead subscriber who hasn't tried to the Team Game Finder, give it a look. And if you've never tried Stathead, sign up today and your first month is on us!

Biographical Updates and New Data for Negro Leagues Players

4th April 2022

Thanks to our partnership with the Seamheads Negro League database, we recently released the first update of Negro League data since the project first launched in June of 2021. This update includes many incremental improvements to player biographical information, including:

-Full names (For example, Mike Woolridge was corrected to Eddie Woolridge)

-Height/weight (For example, Perry Hall now has his height and weight listed)

-Handedness (For example, Curtis Hollingsworth was changed from a right-handed pitcher to left-handed)

-Birth information (For example. Ameal Brooks’ birth year was changed to 1907)

-Death/burial information (For example, added death date and burial information for Willie Nixon)

We’ll also be making additional biographical updates to player school (high school and college), photos, and nicknames).

Along with the biographical updates, many new box scores were uncovered and recorded with some players having significant additions to their player records. Some notable cases include:

-Kansas City Monarchs All-Star Herb Souell saw 186 plate appearances added to his record, the most of any player. Souell did quite well in the newly discovered games, raising his career slash line from .287/.334/.360 (102 OPS+) to .294/.341/.368 (106 OPS+).

-Hall of Famer Willard Brown had 119 plate appearances added, the second most after Souell. His career batting average rose from .347 to .350.

-New Hall of Famer Buck O’Neil was next with 114 new plate appearances. He added two points in batting average and three home runs to his career totals.

-Hilton Smith and Verdell Mathis tied for the most innings added to their records with 69⅓. Smith added four wins and four losses, but saw his ERA drop three points. Mathis, meanwhile, went 6-3 in the new games and shaved 0.13 off his ERA. The vast majority of Mathis’ new innings came from his 1944 All-Star campaign. Now instead of a 1-1 record and 3.78 ERA, he is listed as 7-2 with a 2.85 ERA.

-Jim LaMarque didn’t have as much success in his 65 newly discovered innings. He went 3-6 and saw his ERA climb from 3.17 to 3.37.

Perhaps no player better illustrates the evolution of Negro Leagues data quite like Neil Robinson. Robinson was a long-time outfielder for the Memphis Red Sox for the last dozen years of the Negro American League. Robinson was an All-Star in eight of those seasons. Memphis is one of the teams missing the most box scores, so Robinson’s career record has had relatively few games for someone with so many All-Star appearances.

Robinson was previously credited with 1,164 plate appearances. As part of this update, 243 of those were discovered to not actually be his. The first three years of his career (1930-32) have now been reassigned to Johnny Robinson. Several of Neil’s games were also found, however. 80 plate appearances were added to his record and his OPS+ shot up from 133 to 140 (as a result of both removing Johnny’s games and adding his own).

This update illustrates how we’re very much in the midst of the Golden Age of Negro Leagues research. If you’d like to learn more about the Negro Leagues, we recently published a Resource for Educators (but it’s really for anyone!) to share the incredible story of the Negro Leagues—from the pioneers of Black Baseball in the late 19th century through the formation of the Negro Major Leagues and into the impact of integration on the American and National Leagues.
