GLASGOW, Scotland – The debutant Alex Arthur Jnr, son of Scottish star Alex Arthur – a former WBO champion at junior lightweight – opened his career at light heavyweight, weighing a well-muscled 171lbs at Friday’s weigh-in. He defeated London’s Robbie Chapman, 13-50-9 (2 KOs), over four rounds by 40-36.

The tall southpaw Arthur scored with a strong left to the body early on, and moments after crashed in a left hook-left uppercut.

Chapman was almost instantly forced to cut a very defensive figure, with the debutant menacing throughout.
