The Korea Baseball Organization had their Opening Day this week, and Baseball Reference will be tracking 2020 KBO stats as the season moves forward. In addition to the current season, we have filled in our site's KBO history. Now we have individual and team batting and pitching statistics back to the league's founding in 1982, as well as fielding statistics back to 2001.

You can now back and look at MLB players who made a stop in KBO, such as Julio Franco's 22-HR, 110-RBI season in 2000 (at age 41!), or Eric Thames' 3 seasons with the NC Dinos before making his MLB return with the Milwaukee Brewers.

As for current players to look out for, you have former Minnesota Twin ByungHo Park, who already hit a home run on Opening Day this week and is hoping to notch another 30-HR KBO campaign under his belt. Keep an eye on veteran Kia Tigers pitcher Hyeon-jong Yang, who had one of his best years in 2019. Recent MLB players who are making their KBO debuts in 2020 include White Sox/Brewers infielder Tyler Saladino and journeyman starting pitcher Dan Straily, his last MLB appearance coming with the Baltimore Orioles.

We're excited to keep track of another active baseball league (check out our 2020 CPBL statistics as well!). Please let us know if you have any comments, questions or concerns.

In February, Basketball Reference made a major update in incorporating Daniel Myers' BPM 2.0, which aims to estimate a player's performance relative to league average by using a player's box score information and his team's overall performance. This statistic is also calculable at the game level, and we've made it easier to look through this by making BPM searchable in Basketball Reference's Game Finder, one of the many tools you can find in the site's Play Index.

BPM 2.0 is searchable back to the 1984-85 season, when we first have 100% coverage of all the statistical components needed to calculate this. It's important to note that BPM is a rate stat, so setting a minutes played threshold will be important. Here's a look at the top games in our system using a couple of different thresholds:

Minimum 10 MP

Minimum 20 MP

Minimum 30 MP

Minimum 40 MP

In addition to the Game Finder addition, Basketball Reference now has mouseovers in the advanced section of box scores that display the offensive and defensive BPM breakdowns, as well as Value Over Replacement Player prorated to 82 games. For more information on how BPM 2.0 is calculated, please consult Daniel Myers' explainer. Stay tuned to the Sports Reference Blog for the latest additions to Basketball Reference!

This week, we launched Stathead, a powerful suite of tools that allow you to use our websites's massive database of statistics to research and answer questions. With a Stathead subscription, you can run customized searches through 100+ years of career statistics, season statistics, game statistics, splits and play-by-play.

You can try Stathead for free for a month, and we want to make sure that you get the most out of both your trial and your subscription. So we're launching a video series that will explain what each research tool is and how you can get the most out of it! Welcome to Stathead Tutorials!

If you haven't read it already, please read Mike Lynch's rundown of our new Stathead/Baseball service. I'm going to lay out some of the background for this change and explain some of the changes.

As I laid out in our post from early March, we are making changes to our Ad-Free and Play Index products.

Here is the thrust of what we said in March.

So we are making some changes. The Play Index for each site will be moving to Stathead.com. Stathead.com will become the center for all of our subscription products. We expect these products to include tools and information beyond just a redesigned set of Play Index tools. This won't happen all at once, but we'll start with baseball and then proceed through the remainder of our sports. Also, we will be ending our ad-free product and instead Stathead memberships will have ad-free built-in. There just aren't enough users to justify a separate ad-free product. These changes will begin this month and continue through April on baseball and then continue with the other sites after that.

If you are a subscriber, we will make every effort to make certain you are happy with the options we provide to convert your ad-free or Play Index subscription over to Stathead including the option of a refund on your subscription. You will be hearing more from us about the changes over the next few weeks as we will email users directly.

If you've looked at the cost of Stathead/Baseball vs the Play Index, you'll notice we've gone from $36/year (+ $20/year for ad-free) to $8/month. I realize this is a significant increase. As I said in my original post, we are extraordinarily reliant on ad revenue. Back in early March this seemed problematic. Now with the complete collapse of the advertising market it has the potential to be lethal. If you don't block our ads, you may have noticed that we now have more ads on our pages. This is in response to the downturn in ad revenue. Sports Reference is doing fine right now, but if we want to continue to succeed and also be aligned with the needs of our users, a healthy stream of subscription revenue is vital.

We also feel our products warrant this price. The only comparable products to our Stathead tools come from Elias and STATS LLC and would cost you $10,000+ a year to subscribe to. You could create your own from Retrosheet data, but that would probably take more than $8/month of your time to maintain.

We are using monthly billing for at least the first few quarters, so that we can monitor more directly the success we are having in recruiting and maintaining subscribers. We have discussed adding an annual billing option in the future.

For the time being, we will be maintaining both the legacy Play Index site (which has been free since the start of March) and the new site, but before too long we will take down the old Play Index site, probably late May. We are also working on converting the other Play Index sites. First will be hockey and then probably basketball after that.

We realize there aren't games being played and that you might be facing your own financial challenges at this time. Therefore, we are offering the first month free for all users. And then, until the leagues start playing games, we will be giving users the option of claiming additional free monthly subscriptions. We'll provide more details on the latter plan as we approach the time for subscriptions to be renewed.

If you are a current subscriber, we will be emailing you with information about how we will be converting your subscription to the new system and of course, we will provide your money back if you are unhappy with the conversion to Stathead that we are offering you. Our goal is to give you a more than fair deal and see you join us on stathead.com.

Please feel free to reach out to us if you have questions or concerns.

Today Baseball Reference is excited to announce the debut of most powerful set of publicly available research tools in the game. We're calling it Stathead and you can sign up for a free month of access here. These tools may be familiar to some of our users from the Play Index. If you're a current Play Index subscriber, your Play Index login will also work on Stathead. You can try it out here. For some background on this project, please see this blog post from Sports Reference president Sean Forman.

Stathead subscriptions provide access to a suite of tools that allow users to run customized searches through 100+ years of career statistics, season statistics, game statistics, splits and play-by-play. These tools are omnipresent in every press box, broadcast booth, agency and front office in Major League Baseball. We're happy to offer access to these professional tools for the low cost of $8/month. Even better, for a limited time we're offering the first month FREE.

On the Sports Reference sites that cover professional leagues, we have tables that track team averages in various statistics over the league's history so people can get a sense of how stats have gradually changed as their respective sports evolved. You can see examples of this on Basketball Reference and Pro Football Reference.

We've added this feature to College Basketball Reference so you can see the averages for all Division I schools since 1947-48. The Teams column shows the growth of Division I from less than 150 teams in 1950 to 350 teams in 2020. You can also see the gradual rise in teams' usage of the three-pointer, mirroring its growth in the NBA, as well as the gradual decline in turnovers committed over the past three decades.

Please check out the new game averages table at College Basketball Reference, accessible from the site's Seasons Index. If you have any questions or suggestions, feel free to contact us through our feedback form.

Last August Basketball Reference extended its coverage of play-by-play all the way back to 1996-97 (the earliest season for which comprehensive, digitized NBA play-by-play data is available). As we teased at the time, we hoped to use the play-by-play to build out other features. In October we added the ability to break down our box scores since '96-97 by the quarter or half. Today we're happy to announce that many features that we've had available back to 2000-01 for many years have now been extended back to 1996-97.

The 2020 WNBA Draft will take place tonight, with the New York Liberty owning the first overall pick. Basketball Reference continues to gradually expand its WNBA coverage, and in honor of the occasion we've added the league's draft history. In addition to the rookie draft held yearly, we also have the various dispersal, allocation and expansion drafts performed over the league's history, as well as the Elite draft of 1997. As you can see in the 2019 rookie draft table, we also include college or former international team, as well as their career WNBA stats.

If you have any questions or suggestions, feel free to contact us through our feedback form.

FBref carries a wide array of advanced stats powered by Statsbomb to help give you all the needed context and analyze a player's performance from as many angles as possible.

With the current state of sports being mostly halted due to coronavirus concerns, the Chinese Professional Baseball League is in a rare position as they had their Opening Day and are planning to fill a regular schedule, albeit without spectators. Baseball Reference tracks various foreign leagues already, and we're happy to report that we will be receiving 2020 CPBL statistics as the season moves along.

The first game of the season was a win for the Uni-President 7-Eleven Lions over the Chinatrust Brothers. The Lions' Opening Day starter on the mound was Ryan Feierabend, who pitched for the Toronto Blue Jays in 2019. Former Seattle Mariner Ariel Miranda was the Brothers' starting pitcher. The only homer of the game was launched by Kai-Wen Zheng, who's been with the Lions since 2016.

We've also filled in CPBL history so now we have player stats for the league since 1990. For example, on Manny Ramirez's page we finally show his .352/.422/.555 campaign in 2013 with the EDA Rhinos (at age 41, no less).

2020 CPBL statistics will be updating daily so keep up with the league on Baseball-Reference! Please let us know if you have any comments, questions or concerns.
