I’ve written before about how much direct influence a manager actually has in the final win-loss record of a team over the course of a season, but I never actually believed the in-game decision of a baseline coach would play that much of a factor in the outcome of a game.
That being said, we’ve all seen games where a third base coach will make a bonehead decision to wave home a lumbering catcher, only to have him thrown out at the plate by a mile, and later have to ultimately see the game lost by a run.
