Diocesan Boys' School (DBS) look set to repeat a sweep of the grade titles at the Hong Kong and Kowloon Division One inter-school championships. The boys from the Mongkok institution, who achieved a rare 'grand slam' last year, lead the rankings in two of the three grades going into the final day of competition at Wan Chai Sports Ground today. In the chase for the girls' title, Good Hope School are in pole position and look primed to take the honours in at least two grades. La Salle College, DBS' main rivals in recent years, have a slim lead in Grade B, and their coach, Chan Chau-mo, said he was confident his boys could upset any DBS plans to dominate the competition again. 'Our Grade B boys have performed very well and I hope we can continue to do well and clinch the honours,' said Chan. 'One of DBS' best sprinters in Grade B, Cheung Ho-bong, is out injured, and that has given our boys encouragement. I still think DBS will win the overall championship. We don't have the strength in depth to beat them in Grade A. It's become very tough to win the overall title. 'For us it is the same situation as before. Our best athletes leave the school after Grade A and it is hard to find replacements. We will need to start rebuilding from Grade C again, and plan for the future. We used to be the strongest in Grade C, but now DBS are. They have improved a lot and that has given them an advantage.' Diocesan Girls' School (DGS) and Heep Yunn School are hot on the heels of leaders Good Hope in the girls' competition. 'I think we can win in the A and B grades,' said Good Hope coach, Raymond Tam Yiu-cheung. 'It really depends what happens in the relays. If there are no unexpected mistakes, then we should win. DGS will surely win Grade C. 'We have prepared well for the championships. We held training camps for six days each during the Christmas holidays and Lunar New Year. We are especially strong in field events now. 'We should do well in the middle-distance races where Grace Ng Hei-man, Kristy Yu Ki-ching and Katherine Ma can win points for us.'
