Sheffield Sharks suffered an embarrassing start to 2015 as they were beaten by BBL basement club and Yorkshire rivals Leeds Force.
The Force, in their first season in the top-flight, trailed 57-46 in the fourth quarter but went on a 16-5 run - capped by a James McCann three with 16 seconds to play and a free throw by Armand Anebo - to seal the match.
Sharks, still without point guard BJ Holmes, entered the game in good form after back-to-back victories over the Christmas period but couldn’t find a way past a determined Leeds defence.
Former Junior Sharks player Will Hall made an impression in the first quarter as his six straight points gave Leeds an early 12-8 lead.
However, Sharks point guard Nick Lewis scored five in a 7-0 close to the period and Zach Gachette added a two to open the second quarter as Sheffield led 17-12.
New Force signing Sam Attah single-handedly kept his team in the contest before half time.
The recruit from Durham Wildcats scored 14 of Leeds’ 19 points as the first half ended tied at 31-31.
An Attah two briefly put Leeds ahead at the start of the third quarter before a 5-0 Sharks run made it 36-33.
Sheffield could get no further clear than 45-40 as Force pegged their hosts back to 48-46 heading into the final quarter.
Sharks moved 55-46 ahead before Force took the lead with a 12-2 burst.
Skipper Mike Tuck’s three seemed to be enough for Sheffield to claim victory but Leeds had the last word to stun the home crowd.
