Over a 23-year career as a Major League manager, Piniella posted a record of 1,835-1,713 with the Yankees, Reds, Mariners, Rays and Cubs.
The Findlay Market Parade, which begins at 12 p.m. ET, ahead of the 4:10 p.m. first pitch between the Reds and Phillies, often reaches back to Reds history for the grand marshal. Last year, duties were shared by "The Nasty Boys" trio of Norm Charlton, Rob Dibble and Randy Myers. Previous years included Davey Concepcion, George Foster and Aaron Boone.
Parade organizers and the city of Cincinnati also announced that the 2016 event will return to its long-established route after a construction detour brought changes in recent years.
