Inside baseball is a strategy in baseball that centers on tactics that keep the ball in the infield.
It was developed by the 19th-century Baltimore Orioles and promoted by John McGraw.[1] In his book, My Thirty Years In Baseball, McGraw credits the development of the "inside baseball" to manager Ned Hanlon.[2] In the 1890s, this type of play was referred to as "Oriole baseball" or "Baltimore baseball".[3]
