The Grand Slam in baseball refers to a player hitting a home run with the bases loaded, resulting in four runs being scored in a single play. In Black history, several African American players have achieved the milestone of hitting a Grand Slam in Major League Baseball.

One of the most notable instances of a Grand Slam in Black history was when Jackie Robinson, the first African American player to break the color barrier in MLB, hit a Grand Slam on June 24, 1956, while playing for the Brooklyn Dodgers. This momentous achievement by Robinson further solidified his place in baseball history and his impact on breaking down racial barriers in sports.

Other notable Black players who have hit Grand Slams in MLB history include Willie McCovey, Reggie Jackson, Ken Griffey Jr., and David Ortiz, among others. Each of these players has left their mark on the game of baseball and contributed to the rich history of African American athletes in the sport.
