A Hall of Fame pitcher, a future Hall of Famer slugger, and a guy who has awesome hair.
Randy Jones, San Diego Padres
Jones led the National League in losses in 1974. The next season, he won 20 games, led the NL in ERA, and came in second in Cy Young voting. The next season, two years after leading the league in losses, he won the Cy Young Award, winning the most games in the league. He never again had a winning record, and finished his career losing more games than he won, but the Padres saw fit to retire #35 in his honor in 1997, seventeen years after he threw his last pitch for the team.
