Earl Weaver

Earl Weaver never played a day in the major leagues, a fact that only made his managerial supremacy more delicious. He built his philosophy in the minors, a sharp-eyed second baseman who learned the game's granular details from the dirt up. Taking over the Baltimore Orioles in 1968, he imposed a new order. Weaver was a volcanic presence in the dugout, famous for his theatrical arguments with umpires, but his genius was coldly analytical. He despised the sacrifice bunt, loved the walk, and famously preached waiting for the 'three-run homer.' His teams, built on stellar pitching and the defensive wizardry of players like Brooks Robinson, played a methodical, powerful brand of baseball. He won a World Series in 1970, four American League pennants, and over 1,400 games, all while constantly scribbling notes on index cards and out-thinking opponents with platoons and matchups decades before such tactics became commonplace.
