Baltimore Chop

"A manner of hitting by chopping the ball into the ground immediately in front of home plate with the design of making the ball “hop” into the air, either high enough to allow the batter to reach first base before the infielder can field the ball and throw it to first base. Another goal is to chop the ball hard enough to have it ricochet over the infielders’ heads. The term is derived from the style of play of the 1894 Baltimore Orioles, who led the National league in batting by often using this style."
