Silverio rose to prominence in 1972, when he captured a rare double feat, winning the International Greenhills Grand Prix and, two months later, the Royal Rally of Champions.
Silverio became involved in basketball when he formed the Komatsu Komets/Toyota Comets (Toyota Athletic Club) in 1973 which participated in the MICAA. Along with being its team manager, he became its head coach in 1974 after coach Nilo Verona left the team. Silverio transferred the franchise to the Philippine Basketball Association in 1975 as one of its pioneer members. In the PBA, he continued as the team's manager and head coach until 1979, leading the franchise to five championships and six runner-up finishes.
In December 1979, Silverio resigned from the team after management decided to reinstate players Ramon Fernandez, Ernesto Estrada and Abe King in Game 2 of the Invitational (3rd) Conference championship finals. Silverio did not field these players in during the conference, claiming that the three deliberately “didn't play their best” in a losing finals stint against Royal Tru Orange during the 1979 Open (2nd) Conference. Toyota eventually won the title on December 15, 1979 with assistant coach Fort Acuña, beating arch-rival Crispa in four games.
PBA All-Star Games (1975, 1989)
During the PBA's inaugural season, Silverio coached in the pioneering version of the PBA All-Star Games on December 23, 1975, called the PBA Ovaltine Dream Games. Silverio's Ovaltine Yellow squad lost to the Ovaltine Brown team coached by Baby Dalupan, 126-123 in the third and deciding match.
In 1989, Silverio coached the Rookie-Sophomores-Juniors All-Stars during the 1989 PBA All-Star Weekend, losing to the Veteran All-Stars coached by Baby Dalupan, 132-130.
Crispa-Toyota Reunion Game (2003)
In 2003, Silverio participated in the Crispa-Toyota reunion game during the 2003 PBA All-Star Weekend, coaching the Toyota team to a 65-61 victory.
