Kallio entered the majors in 1918 with the Detroit Tigers, playing for them two years before joining the Boston Red Sox. In his rookie season, he showed promise as a solid starter for Detroit, going 8-14 with 70 strikeouts and a 3.62 ERA in 181⅓ innings pitched. But he developed a chronic bursitis that eventually ended his career, pitching only 22 innings the next season. He went 1-4 for the Red Sox in 1925, his last major league season.

In a three-year career, Kallio posted a 9-18 record with a 4.17 ERA in 49 appearances, including 27 starts, 10 complete games, two shutouts, one save, 75 strikeouts, and 222⅓ innings of work.

Following his playing career, Kallio worked as a coach and traveling secretary for the Portland Beavers (1943) and later scouted for the Chicago Cubs (1946). He died in Newport, Oregon at age 86.
