The 1980 Oakland Athletics season was the team's thirteenth season in Oakland. The A's, under first-year manager Billy Martin, began the season with low expectations following their insipid 1979 campaign. Strong performances from pitchers Mike Norris, Matt Keough, and Rick Langford, along with the brilliant play of breakout star (and future Hall-of-Famer) Rickey Henderson, paved the way for a staggering 29-win increase over the previous year's output. The Athletics, only one year removed from baseball's worst record, swung to a second-place finish behind their 83-79 record.
