Both players will be pulling double duty of sorts on Opening Day. Concepcion was already named last month as the grand marshal of the 95th Findlay Market Opening Day Parade. Larkin will be performing his regular job as an ESPN analyst on Baseball Tonight, which will base its pregame show live on Crosley Terrace outside of Great American Ball Park.
Concepcion enjoyed a 19-season career spent entirely with the Reds from 1970-88, and he was named team captain in 1983. He was inducted into the Reds Hall of Fame in 2000, and his No. 13 jersey was retired by the Reds in 2007.
Larkin had his own 19-season career, all in his hometown of Cincinnati, and was named team captain before the 1997 season and entered the Reds Hall of Fame in 2008. His No. 11 was retired in 2012, the same year he was inducted into the National Baseball Hall of Fame in Cooperstown.
