Sheffield, with Joel Abbott contributing another seven goals, looked on course for victory after building an 11-8 lead. But Portobello then struck back, levelling with two goals from Ben Scott and a fifth of the match from Ed Grundy. Only near the end did Sheffield retain a 100 per cent record from five matches thanks to two goals from Connor Carpenter (Picture: Trevor Hyde).
