I’m a designer and developer with over twenty years of experience with tech companies of all types—from tiny startups to billion dollar unicorns. I lead design at Sports Reference, LLC. We make Baseball Reference, Basketball Reference, Pro Football Reference, Hockey Reference, FBref, College Basketball Reference, College Football Reference, Stathead, Immaculate Grid, and Immaculate Footy. Previously, I was part of the product teams at ezCater, Dribbble, HubSpot, and PatientsLikeMe.
In my free time, I’m a baseball historian focused on the Negro Leagues and Latin American baseball. My work, both personally and professionally, focuses on the intersection of statistical analysis and historical preservation. I enjoy building genuintely loveable and aggressively functional products that support these goals. I have been a member of the Society for American Baseball Research 2013. I’m also a Borussia Dortmund supporter.

I love to make things. Here are a few things I’m working on.
I’m thrilled to share that I’m working with McFarland & Company, Inc. on my first book, tentatively titled Salón de la Fama: Immortals from Latin America’s Baseball Halls of Fame. The book explores the history and inductees of seven prominent Baseball Halls of Fame in Latin America: the Baseball Halls of Fame in Cuba, Mexico, Puerto Rico, and Venezuela; the Dominican Sports Hall of Fame; and the all-encompassing Latino and Caribbean Baseball Halls of Fame. Following a brief history of each institution, the focal point of “Salón de la Fama” is a biographical register of all 867 inductees, ranging from global superstars to unsung domestic pioneers. My goal is to provide readers with the definitive introduction to Latin American baseball history’s characters and storylines. You can read more at my post announcing the book.
The 4,000 Professional Hit Club is an exclusive group of 23 players confirmed to compile 4,000 hits as a professional. We count hits collected in any competitive domestic leagues, playoffs, and international tournaments. We do not include hits compiled in an instructional or non-competitive setting (such as Spring training or instructional leagues) or exhibition games (such as All-Star games and barnstorming contests). The research team includes myself, Von Spalding, and Scott Simkus. I presented at SABR’s 53rd annual convention on behalf of the team and introduced the club to the baseball research community.
More coverage:
The 25th Infantry Wreckers were an all-Black Army baseball team that rose to prominence in the years surrounding World War I due to a dominant roster that included Hall of Famer Wilber “Bullet” Rogan, Negro League stars Oscar “Heavy” Johnson and Walter “Dobie” Moore, and several other players who had careers in the Negro Leagues. I collected box scores for the team’s time in Hawaii and built this site to share (for the first time) their statistics.
Before Jackie Robinson re-broke the color line in 1947, there was an abundance of Black and Afro-Latino talent playing baseball outside of the American and National Leagues. These stars played not only in the Negro Leagues, but also in leagues all over the Western Hemisphere. This personal project collects stats for many of these stars, such as Silvio García, Lázaro Salazar, and Ramon Bragaña. I also collected stats for modern star Julio Franco (including over 4,400 professional hits).
My exploration into the 25th Infantry Wreckers began as part of my research for my first contributions to the SABR Biography Project. So far, I have written biographies for Oscar “Heavy” Johnson, Walter “Dobie” Moore, Jesse “Hoss” Walker (co-written with Bill Staples Jr. for a book about the 1939 Baltimore Elite Giants), and Hurley McNair. I am currently working on the bio of Panama’s León Kellman.
My friend and fellow researcher Graham Womack of Baseball Past and Present collected Hall of Fame Veterans Committee voting history (something that is notoriously difficult to find). I built this site to make it easier to navigate.
Many years ago, I played guitar and bass in local bands. In 2014, I started recording music again on my own. I occasionally release new music, such as:
These projects are no longer being updated, but I am very proud of them.
An alternate Hall of Fame populated by a mathematical formula, I launched the Hall of Stats in 2012 with the help of my friends Jeffrey Chupp and Michael Berkowitz. At the end of 2023, I announced that I will no longer be updating the site (archived version).
This podcast covers the Baseball Hall of Fame’s Era Committees. Guests have included Graham Womack, Jay Jaffe, Graig Kreindler, Mark Armour, Gary Ashwill, Scott Simkus, Kevin Johnson, Dave Metter, and more. I briefly hosted another podcast called The Outsider Baseball Notebook, which chronicled my journey learning about the Negro Leagues and pre-segregation baseball outside of the Negro Leagues.
Jorge Colón Delgado, official historican of the Puerto Rican Baseball League, reached out to me about helping him produce a webinar series about the relationship between Negro League stars and Puerto Rican baseball. The series has covered stars such as Josh Gibson and lesser known legends such as Francisco “Pancho” Coimbre. For this series, I act as moderator and I am lucky to be able to sit back and learn from Jorge and other panelists.
I’ve been on several podcasts to discuss a variety of topics (such as our work at Sports Reference, Negro Leagues statistics, the Hall of Fame, and individual players). Want to chat? Reach out to me on Twitter or LinkedIn or you can email me at ad [at] sports-reference [dot] com.

I am also available for speaking engagements about the work we’re doing at Sports Reference or any of my personal research topics.
Several months after giving my 4,000 Professional Hits presentation at the SABR national convention, I joined the SABR Clyde Sukeforth chapter and gave an updated presentation with the latest research. Von Spalding, my research partner on the project, joined me.
