Baltimore Chop

A ball hit forcefully into the ground near home plate, producing a bounce high above the head of a fielder. This gives the batter time to reach first base safely before the ball can be fielded. An important element of Baltimore Orioles coach John McGraw's "inside baseball" strategy, the technique was popularized during Major League Baseball's dead-ball era, during which baseball teams could not rely on the home run.

To give the maximum bounce to a Baltimore chop, Orioles groundskeeper Tom Murphy packed the dirt tightly around home plate, mixed it with hard clay and left the infield unwatered. Speedy Orioles players like John McGraw, Joe Kelley, Steve Brodie, and Willie Keeler— who once legged out a double off a Baltimore chop - most often practiced and perfected it.

In modern baseball, the Baltimore chop is much less common, usually resulting when a batter accidentally swings over the ball. The result is sometimes more pronounced on those diamonds with artificial turf. The technique still sees use in softball. Relief pitcher Jose Arredondo recorded his first major league hit via a Baltimore Chop to third base, although it presumably was inadvertent in nature, as relief pitchers rarely get at-bats and may have a "just make contact" approach at the plate.
