CHAOS erupted in the Super Commercial Cup tournament amidst angry scenes when a second power failure forced play to be cancelled at the Southorn Stadium last night. Basketball officials were left fuming at the last-minute cancellation having been assured three times yesterday afternoon by the Hong Kong Playground Association (HKPA), managers of the Wan Chai stadium, that there would not be a repeat of Tuesday night's fiasco when another power failure plunged the stadium to near darkness, forcing play to be delayed by an hour. Last night, HKPA officials blamed a short-circuit problem with the stadium's power supply which is connected to the Mass Transit Railway's (MTR) Wan Chai station, situated just next to the 1,900-seat stadium. More than 200 spectators waiting outside the stadium were told by stadium officials that their tickets would be valid for tomorrow's games - officially the tournament's rest day. HKPA spokesman Chan Ban said: ''Our electricity supply is connected with the main MTR electrical cable and it needs urgent repairs. There were problems with it a few months ago but it was never repaired properly. ''Spectators will not get a refund from tonight's [last night's] matches but their tickets will be valid for Friday's matches. ''Postponing the matches till Friday is the only way to deal with this problem because it's close to impossible to move the competition to the MacPherson Stadium in Mongkok.'' Hong Kong Basketball Association secretary general, Leung Che-kung, was unimpressed by the HKPA's late cancellation which has thrown the tournament in disarray. ''This is something we really don't need. We could have switched on the power but that would have been far too dangerous and we didn't want a potentially disastrous situation on our hands,'' Leung said. Players warming-up inside the arena for supposedly the first game of the evening between Winling and Guangzhou's Winnerway were left non-plussed when told the night's games were cancelled. Winling's Mack Joyner said: ''It's no fun sitting around and finding out that the game had been postponed at the last moment. It's a real frustrating thing but we're professional athletes and we have to deal with it like professionals.'' Joyner said last night's last-minute cancellation would not have happened in the United States. ''You don't get that problem back home. If there is a problem, they tell you at least a few hours before the game so you don't have to travel to the stadium for nothing. We had to travel all the way from the New Territories tonight for nothing and we could have done something else had we known that the games were off,'' he said. ''We wanted to win tonight real bad and we were looking for a third place in the tournament. But we'll be ready on Friday,'' he added.
