Gonzalez, fiercely determined to get another major fight, wasted no time once again as he jumped on Amponsah from the opening bell with an onslaught of heavy punches.
This was the second fight under new trainer Pedro Diaz for Gonzalez who has looked impressive in both.
Promoter Joe DeGuardia had this to say about the fight "Yuniesky looked very good tonight taking out a normally very tough and durable opponent with ease. I'm really happy with the progress Yuniesky has made under new trainer Pedro Diaz and I'm very confident we will get a major Light Heavyweight fight in the near future".
The event was promoted by Joe DeGuardia's Star Boxing and Boxing Storm Promotions.
Maxwell Amponsah was a former skipper of the Black Bombers, the Ghana national amateur boxing team.
In another fight elsewhere, Welterweight prospect Ed Brown won a workmanlike 8-round unanimous decision over Albert Mensah in a junior welterweight bout.
Mensah who was formerly an idol of the Will Power Gym at James Town in Accra Ghana is still looking for an opportunity to become world champion
