Despite what the MLB has told us for years,
there is actually little, if any, evidence that Abner Doubleday invented baseball in 1839 in Cooperstown, NY.
In reality, the earliest existing set of rules came from somewhere else in New York, in 1837. William Wheaton of the New York Baseball Club (AKA the Gotham Club) came up rules closely resembling baseball as we know it today. In 1845, Wheaton and William Tucker revised the rules, calling them the New York Knickerbockers Club rules—with one major change being the addition of “three outs per inning.”
Daniel “Doc” Adams was a fellow father of modern baseball that you’ve likely never heard of. Adams was instrumental in defining the game: he played in the inaugural match, helped standardize the equipment by hand-making the baseballs and overseeing the bat makers, created the position of shortstop, and presided over the very first Rules Committee. And, most importantly, he drafted the Laws of Baseball—also known as the “Magna Carta of Baseball,” only recently discovered in 2016 (and auctioned off for 3 million dollars!).
We tip our ball caps to Wheaton, Tucker, the Knickerbockers Club, and Adams as the true creators of the game—because it simply wouldn’t be baseball without three-out innings or nine-man teams!
