He is the father of Jason Grilli. The Grillis were the first American father-son duo to both save games in the majors (since saves were made an official statistic). Julio Navarro and Jaime Navarro and Pedro Borbon Sr. and Pedro Borbon Jr. were the previous duos to perform the feat in The Show.
He was inducted into the Syracuse Sports Wall of Fame in 2006. He has worked as a radio and television announcer for Syracuse Chiefs games. While pitching for the Chiefs in 1979, Grilli became a fan favorite at MacArthur Stadium with his "air banjo" routines done to a Doobie Brothers tune during the seventh-inning stretch. He was the relief ace on a team that extended the Columbus Clippers to a seventh game in the Governors' Cup finals before losing in extra innings.
He is the only major league player ever to come out of Gannon University.
