The native of Finleyville, Pennsylvania, threw and batted left-handed, stood 6feet tall and weighed .
Sessi's professional baseball career began in 1937 in the minor leagues and was interrupted by his four years of service (1942–1945) in the United States Army during World War II.[1] [2] During his 14-season minor league career, which ended in 1955, he was known as a power hitter, blasting more than 20 home runs six times, capped by a 45-homer season in 1952 in the Class B Gulf States League.
As a big-leaguer, Sessi compiled two hits and two bases on balls in 29 plate appearances. One of his hits was a ninth-inning, walk-off home run on August 28, 1946, against the New York Giants' Bill Voiselle at Sportsman's Park, which carried the Cardinals to a 3–2 victory.[3] Every win was important for the 1946 Redbirds, who would finish the regular season in a tie with the Brooklyn Dodgers for the pennant, sweep the 1946 National League tie-breaker series, and defeat the Boston Red Sox for the world championship.
