Rudolph Kallio (December 14, 1892 – April 6, 1979) was a pitcher in Major League Baseball who played for two different teams between the 1918 and 1925. Listed at 5' 10", 160 lb., Kallio batted and threw right-handed. He was born in Portland, Oregon.
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.
