A Small Piece of the Brent Honeywell Story

April 11, 2021 by · Leave a Comment 

It’s all over baseball today as the Tampa Bay Rays host the New York Yankees. Brent Honeywell, once the most highly touted pitching prospect in baseball four years ago, took the mound for the first time since 2017, when he suffered a long series of arm injuries. One of those injuries was particularly ugly, when […]

March 26, 2021 by · 1 Comment 

Pitching, pitching, pitching. You may have heard the saying, “You can never have enough pitching.” Of course, if you are going to have good pitching it begins with your starting pitching staff. Which starting pitching staff was the best ever? A few that come to mind right away were the Atlanta Braves of the ‘90s. […]

In 2020, Cuban baseball players took center stage in the pandemic-shortened season. The Chicago White Sox, a team that won more than half its games just twice in the 2010s and not since 2012, finished the season with 35 wins, good for a .583 winning percentage (roughly a 94 win pace over a 162 game […]

Negro Leagues DB Update: 1926 NNL Fielding & Pitching, 32 Home Runs for Suttles

We’ve added newly audited and expanded statistics for the 1926 Negro National League, including fielding statistics, complete pitching statistics, batters’ hit by pitch, and a handful of new games and corrections to the record. While I don’t think that counting stats are, by themselves, a particularly good measure of the quality of Negro league ballplayers, […]

Mike Port’s professional baseball career spanned more than four decades, from 1969 to 2011.

In […]

April 21, 2020 by · 3 Comments 

When baseball resumes, the three-batter minimum rule for pitchers will be implemented. Under this rule, relief pitchers would be required to face at least three batters or to complete the half-inning before they could be taken out. The rule appears to be an attempt to address the related problems of pace of play and length […]

We’ve added data from the 1942 Mexican League, a season of 84-88 games that finished with three teams within two games of first place. Union Laguna de Torreon posted the best record (48-40) thanks to Martin Dihigo, who proved why he’s one of the greatest players in baseball history. The 37-year-old Dihigo not only led […]

Most baseball fans are familiar with the concept of ‘normalizing’ statistics. For MLB statistics, the most basic adjustment is to normalize for park effects. The simplest park normalization calculation takes the impact of a team’s park on runs scored then divides that number, either positive or negative, in half, and then that calculation is applied […]

Major League Equivalents (MLEs) are a series of calculations designed to take non-major league baseball performance and estimate what that performance’s results would look like statistically in the context of the Major Leagues. Bill James gets credit for popularizing MLEs, as he outlined his method for minor league batters in the 1985 Baseball Abstract. James […]

MACK PARK: Friend or Foe?

November 11, 2019 by · Leave a Comment 

Ballparks are not uniform in baseball. Each one has unique dimensions and can be either a friend of Pitcher and foe of the batter, or vice versa. And beyond that, they can be friendly to RH batters, or LH batters, or both, or neither. Over the last decade, we’ve been continually building a “Negro Leagues […]
