Turning professional in 1909 with the Philidelphia Giants, Sergeant Spottswood Poles followed manager Sol White to New York where he spent the majority of his career with the New York Lincoln Giants.
Hearing the call of WWI, he took a break from his career to enlist in the U.S. Army and was assigned to the 369th Infantry Regiment, commonly known as the "Harlem Hellfighters". Sergeant Poles served honorably, earning five Battle Stars and a Purple Heart.
Returning to baseball after the war, Sergeant Poles continued to play professionally until 1923, when he retired to work as a taxi cab driver and also worked as a civilian at Olmstead Airforce Base.
He died on September 12, 1962, in Harrisburg, Pennsylvania and is buried at Arlington National Cemetary.
