William Tolan Gray (April 5, 1871 – December 8, 1932), also spelled Bill Grey, was an American third baseman and utility player in Major League Baseball between 1890 and 1898.

[2] Gray began his career at age 19 as a utility player for the Philadelphia Phillies of the National League.

[6] His 81 plate appearances, 73 times at bat, and 23 games played were all second-best among Philadelphia's bench (Ed Mayer).

[8] Between the two teams, Gray collected 15 doubles, 3 triples, and 1 home run, the first of his minor league career.

It was his most productive season as a player; at age 26, he played in 125 games for the Hoosiers, batting .347, the fifth-highest average on the team.

[2] After trading for Gray, the Pirates made him their starter at third base for the 1898 season;[14] it was the only year in his major league career in which he appeared at only one position.

[5] Gray played for the Milwaukee Creams of the Western League in 1899—playing there from April 28 to August 30 of that year[17]—and moved to the Detroit Tigers and then the Hoosiers again for the 1900 season.

[20] Gray died on December 8, 1932, in his hometown of Philadelphia, as a result of an apparent self-inflicted gunshot wound.
