Joshua Buatsi marked his professional debut with a classy stoppage victory over Carlos Mena at The O2.
The 24-year-old light-heavyweight was joining the paid ranks after claiming bronze at last summer's Rio Olympics and he gave a glimpse of his talent while halting Mena inside two rounds.
With Anthony Joshua watching from ringside, Buatsi made an impressive start to his own career as he quickly overwhelmed the Spaniard with his impressive punch variety.
Mena was nearly toppled by a body shot from Buatsi in the opening seconds and soon wilted to the canvas after another precise punch ripped into his ribs.
Buatsi effortlessly switched his assault from head to body and Mena was taking shots from all angles when the bell ended this early onslaught.
But there was only brief respite as Buatsi ruthlessly racked up his maiden victory in the second round.
A right hand from the South Londoner sent Mena crashing back to the canvas and he was rescued by the referee as Buatsi followed up with another flurry of punches.
