"Rollie" Fingers is a retired professional pitcher. Half a year out of high school, the Los Angeles Dodgers offered Fingers a signing bonus of $20,000, but due to a-then dwindling confidence, Fingers turned down the Dodgers' offer and signed with the Kansas City Athletics for less money.

Fingers played 17 seasons in the MLB for the Oakland Athletics (1968–1976), San Diego Padres (1977–1980), and Milwaukee Brewers (1981–1985). Fingers's effectiveness as a relief pitcher helped redefine the value of relievers within baseball and helped usher in the modern closer role. He is a three-time World Series champion, a seven-time All-Star, a four-time Rolaids Relief Man of the Year, and a three-time MLB saves leader. Fingers won the AL MVP and Cy Young Award in 1981. Fingers retired in 1985 with 341 career saves, the most in MLB history until surpassed by Jeff Reardon in 1992.

Fingers was inducted into the National Baseball Hall of Fame in 1992, making him just the second reliever elected. He is also one of only a few MLB players to have his number retired by more than one club (Oakland Athletics and Milwaukee Brewers). Fingers is widely known for his neatly groomed handlebar mustache.
