SEASONAL crowned their Hongkong Division A1 triumph with a commanding 99-83 victory over second-placed Suntex at the Queen Elizabeth Stadium last night, having clinched the league title in the committee room earlier in the day. The Hongkong Basketball Association (HKBA) ruled that Seapower had fielded an unregistered player when they beat Seasonal last Sunday and awarded the match to Seasonal, giving them an unassailable lead going into their final match against Suntex. HKBA chairman Norman Chan Shui-tim said: ''Seapower admitted their mistake in playing Glenroy Ferguson and apologised to the association for causing the controversy. ''We accepted their explanation that Ferguson failed to make the 48-hour registration deadline because of a delay in his flight and therefore we are not taking further action against the club.'' Seasonal manager Ng See-yuen, however, was dissatisfied with the association's failure to pinpoint who was actually at fault in allowing Ferguson to play when as they should know that the player was not yet registered. ''This is really a joke,'' said Ng before last night's match, adding: ''I want to know who should be responsible and how the association could have let someone play knowing that he wasn't registered. ''If we hadn't found out that Ferguson only arrived on Saturday and lodged the protest, I really think the association would have turned a blind eye on the issue.'' Frankwell's outspoken manager Fung Shiu-wai is also angered that the HKBA have shown such leniency towards Seapower knowing that the club had blatantly infringed the rules. He said: ''This is absurd. The rules were broken and yet there were no penalties.'' HKBA's chairman, Chan, refused to comment further, only saying: ''The disciplinary committee made the decision and if anyone is not happy they can file a protest and we will reopen the case.'' Seasonal, who have failed to win a trophy in the past two seasons, showed they did not need a default to clinch the title as they led all the way to beat Suntex 99-83. They sprang to a 17-9 lead after only five minutes and although Suntex closed the margin to 25-23, Seasonal never fell behind as they pulled away to lead 50-39 at half-time. Suntex reduced the gap to 76-71 midway through the second period but a 13-point spree saw Seasonal build a solid foundation for a commanding victory. David Willard and Suntex forward Eric Strothers shared scoring honours with 29 points apiece. Seasonal finished the season on 20 points, five ahead of second-placed Suntex. The league championship gave Seasonal the first leg of Hongkong basketball's ''triple crown'' which team manager Ng has set his sights on winning this year. The other two events are the Senior Shield and the Super Commercial Cup. Fukien, champions two years ago, clinched third place behind Seasonal and Suntex with 12 points following an 86-78 win over Frankwell. Defending champions Seapower had to be content with fourth position after their win over Seasonal was overturned. They have 11 points following a come-from-behind 80-76 triumph over Regal.
