He made his professional debut on April 19, 1924, for the Philadelphia Athletics under iconic manager Connie Mack. In his rookie season, he pitched 151⅔ innings in 34 games. He was traded to the St. Louis Browns in 1928 and began pitching much more. His 1928 season was his finest year. He pitched 21 complete games with a win–loss record of 20–12. His earned run average that year was his lowest at 3.19. His 1929 season had similar numbers with an 18-15 record. He also led the league in games started (37) and innings pitched (305). He tied the American League lead in shutouts with four. He shared the league lead with George Blaeholder and General Crowder, who were teammates, as well as with Danny MacFayden of the Boston Red Sox.
