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.
In 1931, he had the dubious distinction of leading the league with 24 losses with a high 5.09 earned run average. His final game was on September 18, 1933. He retired with a win-loss record of 111-115, a 4.18 earned run average, 101 complete games in 379 games pitched, 16 shutouts, and 22 saves. As a batter, his statistics were relatively poor. He accumulated a .191 batting average in 648 at bats and hit two career home runs. He never appeared in any post-season games.
He died in McKinney, Texas, on April 16, 1953 at the age of 55.
