His induction is scheduled to start at 6:30 p.m. CT, 40 minutes before the first pitch of the game between the Royals and the Twins.
Toma, who came to Kansas City in 1957 to become the Kansas City Athletics' head groundskeeper, had the same job for the Royals from the club's inception in 1969 through 1995.
For the past several years, Toma has worked for the Twins at their Spring Training facility at Fort Myers, Fla. He's also renowned for his work in the NFL, including every Super Bowl.
Toma, 83, is the first member chosen by a veterans committee created as part of a redesigned voting process established last year. The 16-member committee votes in even-numbered years on the candidacy of non-field personnel as well as players and managers no longer eligible in the regular phase of the voting. The committee consists of Royals Hall of Famers, club executives and media members. Candidates must be named on 75 percent of ballots to be elected.
