Rollie Fingers is one of the greatest and most recognizable pitchers in Major League Baseball (MLB) history. He was renowned for his handlebar moustache and iconic pitching style. Fingers was a relief pitcher who specialized in the split-fingered fastball, a pitch that he mastered and used to great success on the mound.

Fingers had a long and successful baseball career, spanning over 17 years. He began his career with the Oakland Athletics, where he quickly established himself as a reliable reliever. In his first season with the team, Fingers won the American League (AL) Rookie of the Year Award and helped the A's to a World Series title.

Over the course of his career, Fingers was named to seven All-Star teams and won three World Series championships. He was the first reliever to win the AL MVP Award, which he received in 1981. He also won the AL Cy Young Award in 1981, becoming the only reliever to ever win both awards in the same season.

Fingers retired from baseball in 1985 after a 17-year career. During his time in MLB, he accumulated 341 saves, the fourth-highest total in league history at the time. Fingers was later inducted into the Baseball Hall of Fame in 1992, becoming the first relief pitcher to be so honored. He remains one of the most celebrated pitchers in baseball history.
