Silverio put in 6 and a half seasons of Minor League ball for the Angels franchise before finally getting into 15 games in 1970, though it was a rough one as he proceeded to go 0-for-15 at the plate with four strikeouts.
He’d only get into three games the following year, collecting one his in three at-bats, before coming back in 1972 and going 2-for-12 over 13 games, the last of his Big League experience.
There’s no record of any professional ball after 1972, so I don’t know if he played elsewhere. Nevertheless, he finished his MLB career with three hits over 30 at-bats in 31 games, hitting .100 with two runs scored.
