Clarence William "Tilly" Walker (September 4, 1887 – September 20, 1959) was an Americanleft and center fielder in Major League Baseball from 1911 to 1923. Born in Telford, Tennessee, Walker hit .281, and he was one of the first power hitters. In 1918 while playing for the Philadelphia Athletics, he tied Babe Ruth for the AL lead in homeruns with 11. He was the last person to lead the league in that category before the Babe Ruth era. He then slugged 17 home runs in 1920, 23 in 1921, and 37 (with a .549 slugging percentage and a .283 batting average) in 1922. For a time he was among the top ten lifetime home run leaders. He died at age 72 in Unicoi, Tennessee.
