Spencer Harris holds the minor league records for runs (2287), doubles (743), and hits (3617). He played pro ball for 28 seasons, 1921 to 1948. He played four seasons in the majors but 26 in the minors.
Harris, who was born in Minnesota, played for the Minneapolis Millers from 1928-1937. That was a career in itself, but in 1938, at age 37, he began a stint in the Pacific Coast League which lasted from 1938-1945.
In the majors, he had his most at-bats for the Chicago White Sox in 1926 under player-manager Eddie Collins. That year, Spencer was the most-frequently-used backup on the team. He was the same age as teammate Ted Lyons.
