The Other Ballpark That Just Turned 100: Fenway Park wasn't the only ballpark whose 100-year centennial took place on April 20 of this month. Tiger Stadium opened on the same day as Fenway in 1912, but no one affiliated with the Tigers or Detroit marked the occasion. Today, a Google Maps flyover shows what remains at the storied corner of Michigan Street and Trumbull Avenue. "The only acknowledgment of the old ball yard is a small plastic sign," reports Eric Adelson of Yahoo Sports. A volunteer group called the Navin Field Grounds Crew keeps the lot mowed and chalks the lines once a week. The ghosts of baseball past take care of themselves.
