Edward James Delahanty, nicknamed "Big Ed", was an American professional baseball player, who spent his Major League Baseball (MLB) playing career with the Philadelphia Quakers, Cleveland Infants, Philadelphia Phillies, and Washington Senators. He was renowned as one of the game's early power hitters, and while primarily a left fielder, also spent time as an infielder. Delahanty won two batting titles, batted over .400 three times, and has the fifth-highest career batting average in MLB history. He was elected to the Baseball Hall of Fame in 1945. Delahanty died as a result of falling into the Niagara River or being swept over Niagara Falls (undetermined), after being removed from a train while intoxicated.

In baseball, batting average (BA) is determined by dividing a player's hits by their total at-bats. It is usually rounded to three decimal places and read without the decimal: A player with a batting average of .300 is "batting three-hundred". If necessary to break ties, batting averages could be taken beyond the .001 measurement. In this context, .001 is considered a "point", such that a .235 batter is 5 points higher than a .230 batter.
