Jeremy Frank is a 19-year-old from Illinois studying data science at Purdue. He began his Twitter account, MLBRandomStats, in October 2015 as a freshman at Stevenson High School, near his hometown of Buffalo Grove, Illinois.
The Purdue school paper caught up with him for a story last April, and since then, the Lafayette (Indiana) Journal & Courier tracked him down as well to work something up.
It goes back to how this Twitter account seemed to blow up in July, 2018 after Frank posted something rather randomly interesting about Joey Votto’s pop-up rate. It now has 13,000 retweets and 33,000-plus likes.
In May 2019, the CBS affiliate in Chicago also did a piece on “the phenom” who admits he’s “just really good at math.” He’s got more than 56,000 followers now – still rather modest by some measures. Jayson Stark, for example, has 596,000-plus. But …

“I’ve used quite a few Jeremy Frank notes in my Useless Information column over the last couple of years,” said Stark, who currently works with MLB Network and is senior baseball writer for The Athletic. “One I remember is a note about how Yu Darvish had struck out 24 hitters in his last nine innings pitched, with a breakdown of how many strikeouts he stuffed into each inning. I then used his note to do more investigating, and it turned out no starting pitcher had ever struck out 24 hitters in any nine-inning span. That’s amazing, but I would have missed that if Jeremy hadn’t noticed and tweeted about it. So I think I need to tell him: Thanks!”
Frank now has a podcast at Purdue.
Passon is a passionate 42-year-old cable tech from Montana, now in Tacoma, Wash. His podcast, “Romantic About Baseball,” with Adam MacKinnon (who recently did a book for Rockridge Press called “Baseball For Kids” release last April).
Frank and Passon are no doubt discombobulated at this point with no 2020 MLB data to process or road trips to pursue.
Yet they put their heads together a few years back and decided, from the blurb on the back cover of these two books, “One doesn’t have to be a statistics professor to appreciate the game from a numerical perspective.”
A format that’s deceivingly simplistic ends up speaking volumes about what you can discover and precociously slip into any record-keeping book about the history of Major League Baseball.
Frank and Passon have now put together two of three volumes of material on, well, stuff they’ve found and, as the cover suggests, never thought to look for.
As the first volume handles the game’s dead-ball era going back to its 1876 roots (actually, it precedes that with a discussion of how The National Association of Professional Base Ball from 1871-75 laid the groundwork) and ending with the eventful season of 1919 – The Black Sox Scandal, a national pandemic that shortened the season, and the emergence of Babe Ruth, the newest edition that is now out takes on a 50-year stretch from 1920 to 1969, which in itself was another noteworthy season – the divisions split into West and East, the league adds on four new teams and it’s a huge adjustment of the rules after a pitcher-dominated ’68 season.
The plan for a third volume will likely cover 1970-2020 – should that last season even happen.
“While it may be a little bit annoying to someone who would need to get all three, trust us, the quality of the content inside each book is greatly enhanced thanks to this decision,” they say in the intro to the first book.

Matthew Silverman – not to be confused with the 44-year-old Harvard-educated President of Baseball Ops for the Tampa Bay Rays – has done plenty of other baseball books that involve collecting material, specifically with his work on New York Mets history.
In the beginning, Dan Schlossberg created a lot of this.
Comparing this one to three years ago – which we can, having both editions here in front of us – the cover tweaks include noting that Schlossberg is now identified as a “former AP sportswriter” (he now can be found contributing to Forbes.com), the forward is now by official MLB historian John Thorn (versus former Dodger Jay Johnstone) and the preface comes from former MLB umpire Al Clark (instead of writer Alan Schwarz). The cover collage also adds Mike Trout as the main figure in the center, replacing Ken Griffey Jr., while Hank Aaron and Eddie Matthews are added (and a group of three old-timers we’d be hard pressed to identify are left off).
