Mike Cook was the key man as Sheffield Sharks' recent BBL Championship resurgence continued.
Cook scored 18 points as Sharks edged Durham Wildcats 85-72 on Friday before a 21-point, 10-rebound game in Sunday's 100-68 thrashing of Surrey United.
Sharks have now won their last four games to strengthen their grip on a Play-off place, having previously lost six matches in a row.
There were also Championship wins for Surrey, Cheshire, London and Glasgow.
Newcastle Eagles won the biggest game of the weekend, beating Leicester Riders 96-90 in a thrilling BBL Trophy final in Glasgow.
Eagles warmed up for that victory with a 101-74 defeat of Bristol Flyers on Friday to remain six points clear at the top of the BBL Championship.

Cheshire Phoenix climbed to third with victory against London Lions, although fourth-placed Riders now have five games in hand, while Lions bounced back to beat Wildcats 83-71.
Glasgow Rocks, in sixth spot, closed within two points of Lions having played two games fewer, after they overcame Leeds Force 67-59 with 22 points from Tayo Ogedengbe to extend their winning run to six games.
In the WBBL Championship, Barking Abbey Crusaders beat Brixton Topcats twice to lock up sixth position and avoid a first-round Play-off meeting with either of the top two teams, Sheffield Hatters or Nottingham Wildcats.
