Baseball field In Major League Baseball, a regulation mound is 18 feet (5.5 m) in diameter, with the center 59 feet (18 m) from the rear point of home plate, on the line between home plate and second base. The front edge of the pitcher's plate or rubber is 18 inches (46 cm) behind the center of the mound, making the front edge's midpoint 60 feet 6 inches (18.44 m) from the rear point of home plate. Six inches (15.2 cm) in front of the pitcher's rubber the mound begins to slope downward. The top of the rubber is to be no higher than ten inches (25.4 cm) above home plate. From 1903 through 1968, this height limit was set at 15 inches (38.1 cm), but was often slightly higher, sometimes as high as 20 inches (51 cm), especially for teams that emphasized pitching, such as the Los Angeles Dodgers, who were reputed to have the highest mound in the majors.
