Longevity

Only two men in U.S. baseball history have ever hit homeruns as teenagers and when they were in their forties: Ty Cobb and Rusty Staub.

As a teenaged Detroit Tiger, Cobb hit two homers; then later he had six with the Philadelphia A's after he'd turned 40. Staub had six as a teen with the Houston Astros and two as an over-40 New York Met.
