A native of Belden, Nebraska and graduate of Upper Iowa University, Alderson was one of many major leaguers who saw his baseball career interrupted by a military stint during World War II.^[1] He began his professional baseball career in 1942 with the Zanesville Cubs of the Middle Atlantic League. In 1943, he pitched for the Nashville Volunteers of the Southern Association and earned a late call-up to the Chicago Cubs in late September. During the 1944 midseason, he was optioned back to Nashville, where he enlisted the Navy though he had twice been previously rejected because of a kidney ailment. He was sent to the Naval Training Center in San Diego, California and remained there until being discharged in late 1945. In 1946 he returned with the Cubs but was optioned again to Nashville. He had a 6–8 record and a 4.70 ERA with Nashville that season before retiring.
