According to a fight report on Boxing Scene, Viloria floored Soto three times in the first round despite taking some time to shake off ring rust.
Viloria, coming off a seven-month lay-off, registered his first knockdown after just a minute, and the referee stopped the bout at the 2:02 mark after Soto hit the canvas for the third time.
The bout was touted as a "stay busy" fight for Viloria, who may have earned a shot at champion Roman Gonzalez for an October fight date.
