Frenchman Saidou Sall (10-7-2) had no answer to the London light-heavyweight, Joshua Buatsi (3-0), in Cardiff and was dropped early on in the first-round but argued that it was a slip and jumped straight back up again.
The 24-year-old from Croydon, managed by Anthony Joshua, looked sharp in the opening six-minutes and rocked Sall’s head back often with accurate head shots.
