Baseball Prospectus (BP) is an organization that publishes a website, BaseballProspectus.com, and books devoted to the sabermetric analysis of baseball. BP has a staff of regular columnists and provides advanced statistics as well as player and team performance projections on the site. Since 1996 the BP staff has also published a Baseball Prospectus annual as well as several other books devoted to baseball analysis and history.

Baseball Prospectus has originated several popular new statistical tools that have become hallmarks of baseball analysis. Baseball Prospectus is accredited by the Baseball Writers' Association of America. Four of Baseball Prospectus's current regular writers are members of the Baseball Writers' Association of America and thus eligible to vote for nominees for Major League Baseball's post-season awards and the Baseball Hall of Fame.

History

Baseball Prospectus was founded in 1996 by Gary Huckabay, who recruited the initial contributor group of Clay Davenport, Rany Jazayerli, Christina Kahrl, and Joe Sheehan, with the publication of the first annual set of forecasts. "That first year, BP charged $20 for a statistics guide produced on a photocopier. It printed around 300 copies and sold about 170 to fellow statheads, even though the book was missing the St. Louis Cardinals. 'It was terrible,' recalls Kahrl, 'but it nevertheless didn't discourage us.' Within a few years Brassey's Inc. published the guide, which grew to about 3,000 copies. By 2007 it reached The New York Times bestseller list, topping 70,000 copies at $21.95 a pop."

BP has often been considered the modern successor to Bill James' Baseball Abstract series of books in the 1980s.

The website BaseballProspectus.com began in 1997 primarily as a way to present original sabermetric research; publish advanced baseball statistics such as EqA, the Davenport Translations (DT's), and VORP; and promote sales of the annual book. Beginning in 2003, the site placed most of its new articles, its PECOTA forecasts, and some of its statistical databases in a "premium" section that could be accessed only by subscription. However, in May 2011, BP "announced it has made its entire archive of premium and fantasy content over one year old completely and permanently free to the public".

A number of former regular writers were hired by major league baseball organizations, including, at various points, Keith Woolner (Cleveland Indians), Dan Fox (Pittsburgh Pirates), Mike Fast (Houston Astros), Kevin Goldstein (Houston Astros), and Colin Wyers (Houston Astros). Early writer Chaim Bloom went on to work for the Tampa Bay Rays and eventually became general manager of the Boston Red Sox; he was the first BP alum to become a GM. He was followed soon after by James Click, another former writer and Rays employee who was hired by the Astros as their GM later that month. As of 2020, more than 50 former BP staffers are now employees of Major League organizations.

Given the competing career opportunities for some of BP's best-known and most statistics-savvy analysts, maintaining a fresh supply of sabermetrically sophisticated writers has been a challenge for the site. During the 2009 baseball season, BP ran a multi-week open talent search competition in the spirit of the popular television program American Idol, in which aspiring writers submitted articles for evaluation by BP's staff members, with one contestant a week from among the final ten selected by the staff then voted off by the subscribers. At least three new regular BP writers (winner Ken Funck, Tim Kniker, and Matt Swartz) were discovered through this Prospectus Idol contest.

On March 24, 2009, Baseball Prospectus announced that Nate Silver was stepping down as its managing partner, and Kevin Goldstein was assuming this role. At that time, PEV relinquished its previously announced financial interest in Silver's FiveThirtyEight blog. At the same time, it was announced that BP has a partnership relationship with ESPN.com. Goldstein expanded the website's coverage of scouting and player development.

In January 2010, managing partner Kevin Goldstein reported that one of BP's founding members, Joe Sheehan, had departed the organization. He reported that John Perrotto had been elevated to full-time status on the BP staff and would become the new Editor-in-Chief of BaseballProspectus.com, taking over that responsibility from Christina Kahrl. And he reported that Jeff Euston was joining the BP staff and that Euston's Cot's Baseball Contracts website would be joining the Baseball Prospectus family. In February 2011, Perrotto was replaced as editor-in-chief by Steven Goldman.

In February 2010, BP's "Fantasy Manager" Marc Normandin announced that BP had established a partnership with Heater Magazine. Heater Magazine ceased publication after the 2010 season.

In November 2011, Kevin Goldstein announced that he was stepping down as managing partner in favor of Joe Hamrahi. On March 3, 2012, Hamrahi announced that Steven Goldman was stepping down as editor-in-chief of BaseballProspectus.com; Goldman had taken a position as a lead baseball writer for Bleacher Report. Ben Lindbergh was named managing editor of BP on March 5, 2012 and editor-in-chief on July 13, 2012.

On April 30, 2012, managing partner Joe Hamrahi announced that "Dan Brooks, Harry Pavlidis, and Brooks Baseball have agreed to team up and join forces with Baseball Prospectus. BrooksBaseball.net is the premier site for PITCHf/x analysis and pitch classification".

In March 2015, principal owner Dave Pease and his partners sold the company to a new group led by Jim Walsh, Sean Neugebauer, and Stephen Reichert. Hamrahi departed the organization. In 2018, the site was sold to DIY Baseball, LLC. As of 2020, the president is former BP managing editor Bret Sayre.

Work on other sports

Baseball Prospectus's former parent company, Prospectus Entertainment Ventures (PEV), also ran websites and published books focusing on the statistical analysis of other sports.

Football

For several years, PEV partnered with Football Outsiders for the publication and promotion of Football Outsiders Almanac (ISBN 1-4486-4845-9), before 2009 called Pro Football Prospectus (ISBN 0-452-28847-9).

Basketball

On October 10, 2007, PEV launched Basketball Prospectus a new website for the analysis of men's college and pro basketball, with Joe Sheehan taking the role of managing editor and announcing the lineup of principal writer-analysts for the site. Initially, this website did not require a subscription for access, but it introduced subscriptions in 2011 for access to most of the material on the site. BasketballProspectus.com's first annual book, College Basketball Prospectus 2008–2009 (ISBN 0-452-28987-4), was published in October 2008. It released Pro Basketball Prospectus 2009–10 for purchase online in October 2009. Subsequently, it published both College Basketball Prospectus 2010–11 (ISBN 1-4538-7282-5) and Pro Basketball Prospectus 2010–11 (ISBN 1-4538-6899-2) in both print and online (PDF) modes.

On March 15, 2013, after explaining a week earlier that its key staff of writers had been hired away by ESPN, Baseball Prospectus's Dave Pease declared that Basketball Prospectus would not be publishing any new content.

Hockey

On February 23, 2009, PEV launched the website Puck Prospectus (later Hockey Prospectus), with the intent of providing cutting-edge analysis of hockey. Will Carroll assumed the role of the executive editor, and Andrew Rothstein, the founder of Puck Prospectus, assumed the role of the managing editor. Puck Prospectus published its first annual book, Puck Prospectus 2010–2011 (ISBN 1-4538-1784-0) in both online and print formats. Initially a free site, Puck Prospectus introduced subscriptions in 2011.

Hockey Prospectus's final article was in May 2017.

Internet Baseball Awards

Main article: Baseball Prospectus Internet Baseball Awards

• The annual Internet Baseball Awards (IBA) are based on fan voting. They started in 1991 with the Most Valuable Player, Cy Young (pitcher), and Rookie of the Year awards, in each of the two major leagues. In 1998, an award for Manager of the Year was added in each league.

Theories

Baseball Prospectus writers promote several theories on proper baseball management and analysis, many of which are contrary to those of conventional baseball wisdom.

Clutch hitting

Main article: Clutch hitter § Does clutch hitting exist?

Baseball Prospectus researchers have concluded that there is no repeatable ability of clutch hitting. As writer Joe Sheehan said, "Over the course of a game, a month, a season or a career, there is virtually no evidence that any player or group of players possesses an ability to outperform his established level of ability in clutch situations, however defined." They cite studies which find that there is insignificant correlation between year-to-year performance in clutch situations.

In an article published in 2006, Nate Silver argued that clutch hitting ability does exist to a degree. He argued that although not as important as traditional baseball analysis would suggest, clutch hitting ability was more significant than other sabermetric studies had shown. The article also found there to be a connection between clutch hitting ability and situational hitting, or the ability to adjust a hitting approach to fit the given situation.

Views on traditional statistics

Baseball Prospectus writers often successfully argue that traditional baseball statistics such as RBIs, wins, and batting average are poor reflections of a player's true contributions. For example, they have argued that RBIs are too dependent on factors outside of the player's control, namely the production of other hitters in the lineup. They similarly argue that wins are too affected by factors such as the team's offense and bullpen.

Closer usage

Baseball Prospectus writers assert that teams are typically inefficient in their use of their best relievers. Teams typically assign their most effective reliever to the position of closer, using him in only save situations. According to many Baseball Prospectus writers, a team's best reliever should be used when the opposing team has its best chance at increasing its chances of winning.

Views on sacrifice bunts and stolen bases

Many writers argue that the sacrifice bunt and stolen base are overused in baseball. Teams will often attempt these plays when the score is close. Writers for Baseball Prospectus often argue that teams are, on average, actually lowering their expected number of runs scored. They argue that stolen base attempts are not completed frequently enough for them to be beneficial to the offense. For sacrifice bunts, they argue that the team is giving up more by sacrificing an out than they gain by advancing a runner one base. Their thinking is derived from the grid of expected runs in an inning based on the outs and runner situation, which shows that the sacrifice is detrimental to a team given average players in most of the situations in which it is typically used.

In a series of articles in 2004, James Click argued that sacrifice bunts are beneficial in some situations, dependent on the quality of the batter at the plate and the situation in the game.

Statistical tools

Baseball Prospectus writers use a wide variety of sabermetric tools. Among the major tools that they are credited with inventing are:

• Deserved run average (DRA) – a metric of pitching performance scaled similarly to earned run average that uses a linear mixed model to account for a number of factors outside of the pitcher's control, such as the catcher, the umpire, batter handedness, park effects, and the strength of the defense, among others.
• Deserved runs created plus (DRC+) – a metric of offensive production that accounts for league and park effects, scaled so 100 is league average.
• Equivalent average (EqA) – a combination of various hitting numbers designed to express a player's overall offensive contribution.
• Equivalent Baserunning Runs (EqBRR) – a statistic indicating a player's rate of run production resulting from his baserunning.
• Jaffe Wins Above Replacement Score (JAWS) – a metric "invented by Jay Jaffe to assess a player's worthiness for enshrinement in the Hall of Fame."
• Pitcher Abuse Points (PAP) – a measure of the impact of a particular start by a pitcher on his arm, based on pitch count.
• Peripheral ERA (PERA) – a pitcher's expected ERA based on park-adjusted hits, walks, strikeouts, and home runs allowed.
• PECOTA – a system of player projection based on similarity to previous player seasons.
• Value over replacement player (VORP) – a measurement of the number of runs contributed by a player over the expected level of performance the average team can obtain if it needs to replace a starting player at minimal cost.

Voros McCracken's pathbreaking 2001 article on Defense Independent Pitching Statistics also first appeared on the BP website.

Since 2014, BP has done extensive work to quantify catcher defense, such pitch framing and ability to blocking pitches.

Criticism

Criticism of methodology

Baseball Prospectus, as well as other sabermetric analysts, are criticized for taking the human aspect out of the game of baseball. For example, Murray Chass of The New York Times wrote in an article that he did not want to hear or read about new-age baseball statistics any more (referencing Value over replacement player specifically), saying:

"I suppose that if stats mongers want to sit at their computers and play with these things all day long, that's their prerogative. But their attempt to introduce these new-age statistics into the game threatens to undermine most fans' enjoyment of baseball and the human factor therein. People play baseball. Numbers don't."

Nate Silver, BP's Managing Partner at the time, responded to this criticism in "An Open Letter to Murray Chass", including offering to meet Chass to watch a ballgame. He expounded on the case for a positive impact of sabermetrics on the game of baseball in an article "How Sabermetrics Helps Build a Better Ballgame", published on Baseball Analysts.com.

Another type of criticism comes from those who believe that by broadening its coverage and audience, Baseball Prospectus is becoming more like the mainstream media and losing what made it unique. In response to a question along this line in an on-line chat, Silver wrote:

From a brand standpoint, we're more concerned about differentiation based on quality than differentiation based on where we fall on sort of the "saberpolitical" spectrum.

Criticism of journalistic standards

Baseball Prospectus was widely criticized for publishing and aggressively promoting a 2003 story claiming that banished player/manager Pete Rose had reached an agreement to return to baseball. Will Carroll made the rounds on television and radio, claiming to have spoken to unnamed sources who had actually seen the agreement. Spokesmen for both Rose and Major League Baseball refuted the claim, but Carroll and his colleagues insisted their reporting was accurate. No other news source confirmed the story. In fact, Rose was not reinstated and remains banned from baseball.
