7. Kirby Puckett

Sport: Baseball
Retirement Age (Career): 35 (1984-1995)
Throughout his entire 12-year career Kirby Puckett played for the Twins and guided them to two World Series championships. Fans most fondly remember him for his walk-off homer in Game 6 of the 1991 World Series which is to this day one of the most clutch moments in Minnesota sports history. After his tenth consecutive All-Star season in '95, he was tearing it up during spring training until he woke up on March 28, 1996 and couldn't see out of his right eye. The problem turned out to be glaucoma and after three unsuccessful surgeries, he was forced to retire. Puckett finished his career with a .318 batting average and 2,300 hits. He died from a stroke only 11 years later. R.I.P.
