John Parker has continued his winning start to his professional career with a unanimous points decision on the first undercard fight to his brother Joseph's main event fight against Andy Ruiz Jr.

Parker, fighting at catchweight but aiming to continue at light heavyweight, won all four rounds against Ash McConville from Christchurch.

McConville proved a tough opponent for the 22-year-old Parker, who fought for the first time as a professional on the undercard of his big brother's last fight in October, another win.

Parker impressed with his jab, but struggled to find his range at times. He landed far more punches than McConville, including several right hooks, and neither man was hurt.


Joseph, watching ringside ahead of his world title fight, appeared satisfied with his little brother's work.
