Derby defeated London Towers 92-85 on Saturday night to briefly take a clear lead, but Sheffield joined them last night by beating the Greater London Leopards, the League Champions, 108-83.
The Sharks completed a winning double after beating Leicester City Riders 91-74 in a bad tempered game on Saturday.
Storm's coach Bob Donewald's on-court general was Nate Reinking, who played for him two years ago during his first season at Leicester. Reinking hit 17 first-half points.
Reinking, 25 points in all, 6ft 3in Yorrick Williams, 22 points and 6ft 5in Rico Alderson, 14 points, bypassed London's massive height advantage. After Williams's three-pointer gave Derby a 67-43 lead, the Towers never went closer than 10 points.
Sheffield's Terrell Myers hit seven points in a 15-3 run for a 45-32 lead over the Leopards, then a 15-4 spurt immediately after the break put the home side 68-44 ahead.
John White's return to the Manchester Giants line-up proved to be no compensation whatsoever for the club, having lost Porter Roberts on Thursday under salary cap regulations.
White scored with just two shots out of 17 as the Giants lost 82-69 at home to Thames Valley Tigers while Tony Dorsey, another big summer signing, fared even worse with just one successful shot out of 17 attempts.
The Birmingham Bullets clinched their first win with a 5-0 run in the last two minutes to win 58-54 at Milton Keynes Lions.Reuse content
