Manchester Giants, who beat Towers in midweek and Newcastle Eagles 84- 77 on Friday night, hold first place despite a weekend off. Sheffield Sharks, Derby Storm, Birmingham Bullets and Thames Valley Tigers field the next four places above Towers. Leopards are eighth, behind Newcastle, after losing 95-91 at home to Chester Jets on Saturday, although "home" was in Southend, the third venue this season for the wandering Leopards.
Jets' fourth win in five was clinched by an 11-1 run in the third as Greg Meldrum led their scorers with 20 points.
Leopards' second defeat of the weekend was at Sheffield last night, by 115-81, as the Sharks moved two points behind Giants.
Towers' fourth successive defeat, by 82-72 at Leicester City Riders, drew a sparkling 19 points from former player Karl Brown, in support of 20 from captain Billy Singleton.
Derby, who ended Sheffield's 12-game unbeaten start last weekend, overwhelmed Birmingham with a 19-0 run straddling the third and fourth quarters in their 85-77 win at the NEC. Yorick Williams, called into the England squad for next week's European Championship game with Denmark, led all scorers with 28 points.
Tigers beat Milton Keynes 77-70 and Edinburgh Rocks won their first game of the season with a 97-94 win at Worthing Bears.
