2) Mike Marshall
The 1974 NL Cy Young winner, Mike Marshall did it in an unorthodox way. He had already become one of the best relievers in baseball with the Montreal Expos. Now, with an insane 106 games pitched in relief, Marshall was doing things no one had done before or will be given the opportunity to yet again.
Marshall was available as much as any reliever in history, even finishing 83 games for the Dodgers that season. He was the Cy Young runner-up a year prior, finally getting the acknowledgment once he moved to Hollywood.
Marshall sure seemed to become a victim of being overused as his innings totals dropped in the following years as did the results. He had one last rendezvous with greatness, pitching to a 2.45 ERA in 1978 with the Minnesota Twins then following it up with a league-leading 90 games, 84 games finished, and 32 saves in 1979 for them all while pitching to a 2.65 ERA and logging 142.2 innings in relief.
His career came to an end with the Mets in 1981 when, alongside Jones, he played out another miserable season in Queens. Marshall wasn’t bad, going 3-2 with a 2.61 ERA in 31 games. He walked as many batters as he struck out (8) and after this age 38 season, his last big league game had been played.
