Great Britain captain Drew Sullivan starred as London Lions overcame Worcester Wolves 88-70 on Sunday to secure a third straight win.
Sullivan had 22 points and 12 rebounds in Lions' latest success, which followed an 85-63 defeat of Bristol Flyers on Saturday.
Sheffield Sharks beat Glasgow Rocks to secure their fifth straight win.
"Our goal is to keep playing good basketball as we approach the play-offs," said Lions coach Vince Macaulay.
"We are all beginning to concentrate on our individual jobs. Earlier in the season we were too concerned about what the next person was doing.
"The atmosphere is different in the locker room, and the atmosphere among the fans is different as well."
