Grant was born in
Pittsfield, Massachusetts. He played semipro baseball in Pittsfield and in
Plattsburgh, New York. In 1886, Grant played for the
Meriden Silvermen team of the
Eastern League, based in
Meriden, Connecticut. After Meriden folded during the season. Grant signed with the
Buffalo Bisons in the International League, one level below the major leagues. In an April 1887 preseason game against the Philadelphia Phillies at the
Jefferson Street Grounds, Grant homered and was cited for his "remarkable fielding." During the 1887 season, the 22-year-old batted .353, paced the IL with 11
home runs and 49
extra-base hits, and led Buffalo with 40
stolen bases. In 1887,
Jack Chapman, the Bisons' veteran manager, valued Grant's services at $5,000—a compliment when Chicago had recently sold superstar
King Kelly to Boston for $10,000. During the 1887 season, Grant
hit for the cycle in one game and stole home twice in another. Despite significant racial turmoil that year, Buffalo forced the IL to rescind a proposed color line to keep Grant in town. By 1888, anti-black sentiment was all around the league, and it seemed only Buffalo argued against segregation (possibly because of Grant). While with the Bisons, Grant led the team in batting average every year but was disliked by his teammates. He frequently faced hostile opponents who tried to injure him on the field. When blacks were banned from organized, white-controlled baseball in 1889, Grant went on to become a successful
Negro leaguer for the
Cuban Giants,
Cuban X-Giants, Big Gorhams, Brooklyn Royal Giants, and
Philadelphia Giants into the 20th century. His career ended in 1903. Author Jerry Malloy described Grant as "the greatest Negro baseball player of the 19th century." In the late 19th century, few black hitters matched up with Grant. He had substantial power at the plate, often hitting home runs and very often getting extra-base hits. Grant hit for extra bases every four times he got a
hit. He achieved this even though he was quite small (5'7", 155
pounds). A middle infielder, mostly a
second baseman, Grant had fielding skills widely praised as the best in the league. He was known as "The Black Dunlap", a comparison drawn to the defensive skills of 19th-century white second baseman
