Whitwell (15) became the latest St Ives Boxing Academy talent to star on the big stage when winning the Under 63kg title at the Junior Development Championships - a novice event for fighters with fewer than six bouts behind them. Whitwell overcame a slow start to see off Poppy ONeill of the Ernie Oxers club in Rotherham courtesy of a final-round stoppage. Father and coach Steve Whitwell said: This was a great win for Harli and sets her up nicely for the upcoming National ABC Championships which start next month. Hopefully the success will put her back on the England radar as the selectors showed an interest last season. Two sisters fighting in championships is very rare and it could be a first if they can both make it into the England team. Older sister Shona (17) is also due to be in action next month when representing the England team in a tournament in Bulgaria.
